Maritime satellite communications industry in review [VIDEO]
1. September 2011 by admin.
* At Alan Spicer Marine Telecom we need to keep our ears to the ground (or the water maybe?) and keep tabs with what is going on in maritime communications for all sizes of vessels. We also need to be as forward-looking as possible to be able to provide systems and solutions that will work now but also have a future for some years beyond the installation. Keeping tabs on 3G, 4G, WiFi, WiMax, Satellite, … etc. and taking that towards the marine market is what we strive to do. Coming up with ways to provide the best communications while at the same time finding ways to implement cost savings are paramount in our operations and thinking. The following videos and the information provided came across my desk, so I am sharing them.

Why use microwaves for satcoms?

Why use microwaves for satcoms? antenneX Issue No. 140 – December 2008
By David Jefferies
If so which frequencies?
Frequencies above about 30 MHz can pass through the ionosphere and so are available for communicating with satellites and other extra-terrestrial sources. Frequencies below 30MHz are liable to be reflected by the ionosphere at certain stages of the sunspot cycle. The ionosphere consists of several layers of ionised gas which alter in height during the 24 hour daylight cycle. The ionosphere has an effect on satellite communications even if it does not completely prevent them. Frequencies from about 100MHz to 2 GHz are used for communicating with low earth orbit satellites (LEOs). Since the range from ground station to satellite is only a few hundreds of km, it is not necessary to use high gain ground based antennas. Of course, there is a direct link between the beam divergence angle of an antenna and its directivity and its gain.
• A highly directional antenna concentrates most of the radiated power along the antenna “boresight”. There is no functional difference between receive and transmit modes of an antenna except that power flow is directed inwards to the receive antenna and outwards from the transmit antenna. An antenna has the same efficiency, directivity, and polarisation characteristics in receive and transmit modes. This property is called “reciprocity” and occurs because of the symmetry of the electromagnetic equations when the direction of time is reversed. A high gain antenna is therefore very directional and has to be pointed with correspondingly high precision. It is an advantage if it does not have to be moved in azimuth and elevation. This restricts the use of high gain antennas largely to geostationary satellite applications. Steerable high gain antennas are very specialised and costly. Typically at 12 GHz the pointing accuracy needed for a 1-metre diameter dish is of the order of a degree or two of arc. Sophisticated tracking control apparatus would be required to keep such a dish pointing at a LEO satellite, particularly for mobile applications. One way around the steerability problem is to use an electronically steerable “phased array” antenna. These have intrinsically rather less potential gain than a dish antenna, and require a high degree of electronic microwave complexity.
Frequencies from 1-30 GHz are usually called “microwave”. From 30 GHz, to say 300 GHz the frequencies are referred to as “millimetre wave”. Above 300 GHz optical techniques take over, these frequencies are known as “far infrared” or “quasi optical”. Guided wave techniques are only used up to about 100GHz, higher frequencies use optical bench techniques and free space propagation to get the energy from one part of a circuit to another. This may occur in “overmoded waveguide”, where the microwave energy is concentrated on the axis of the waveguide and falls off at the guide walls. Above about 30 GHz the attenuation in the atmosphere due to cloud, rain, hydro-meteors, sand, and dust makes a ground to satellite link unreliable. Such frequencies may still be used for satellite to satellite links in space. It is arguable that for such applications optical technology is better than microwave carrier technology, particularly in view of the extensive development in fibre optics in recent years. 6-24 GHz are useful frequencies for geostationary satcoms, since fractional bandwidths of a few percent give useful real Hz bandwidths. The fractional bandwidth is defined as the bandwidth in Hz divided by the carrier frequency in Hz. Bandwidth is in short supply because there are only a limited number of geostationary satellite positional slots around the equator. A common frequency band for satcoms is 10-14 GHz. Use is also made of 4-6 GHz but the capacity in this band is only half as much.
Fractional Bandwidth
Fractional bandwidth is defined as (delta f) divided by fo where fo is the band centre and (delta f) the bandwidth in Hz which is occupied by the signal or signals. At 10 GHz, 1% fractional bandwidth gives us 100 MHz of numerical bandwidth, which is sufficient for 10 TV channels each requiring 10MHz bandwidth. At 5 GHz, 1% fractional bandwidth only gives us 5 TV channels of 10 MHz each. The concept of fractional bandwidth is central to satcoms. Many microwave transmission systems can only work over a limited fractional bandwidth. The widest band systems, like dual directional Lange couplers, Travelling Wave Tubes (TWTs), and circulators or isolators, have only 50% to 100% fractional bandwidth. It is possible to make distributed amplifiers with wider fractional bandwidth than this, but they tend to have rather poor group-delay characteristics across the band and have rather specialised applications. So if we are considering say a stub tuner matching network, or a set of filters used to isolate the
transmit path from the receive path and to provide power-combining functions, fractional bandwidths of between 0.1 and 5% are optimum. It so happens that this allows us useful real Hz bandwidth at the frequencies under consideration, 2-20GHz, with enough capacity for important telecoms applications. We see therefore, that it is only a fluke of nature that allows the frequencies which propagate through the atmospheric and ionospheric window also to be sufficiently high that they can carry reasonably large amounts of information with technology which is feasible.
This is summed up by the slogan
• The engineer does what he can, rather than what he would ideally like to do.
Frequency Division Multiple Access (FDMA) allows more than one signal to be modulated onto a single “carrier”. The signals are stacked up in frequency on a number of different “sub-carriers” each of which requires a local oscillator and a filter. Usually the composite signal is passed through a single feed to the satellite antenna. However it is often the case that each channel has its own high power amplifier (HPA) and the signal combining is performed with signal “multiplexers”. The antenna is often common to uplink and downlink. The received signal is separated from the transmitted signal using a “Diplexer” which has both filter and directional coupler characteristics.

Interesting Trivia about L, S, C, X, Ku, K, Ka (commonly discussed in satellite systems) … Did you know? I did not know that!
24. March 2011 by admin.
I just made a blog post earlier where someone asked me to give a one line description of C, Ku, and Ka bands … what does it mean? So I did. But I just saw this stuff on Wikipedia and it just might win you that free cup of coffee. Did you know that “C” band is a “Compomise between S and X bands? Did you know that X band, used in WW II for fire control, and that X was for cross hair as in a gun sight? Did you know that K band was for German Kurz (meaning short?)? And that Ku band was from “Kurz Under” and Ka band was from “Kurz Above”? So you coul really call Ku Band = “Short Under Band” and Ka Band = “Short Above Band”. Also interestingly L band is Long Wave and S Band is Short Wave. But also think of and describe much lower frequencies than these Long Wave and Short Wave bands.
IEEE US
Band Frequency range Origin of name[2]
HF band 3 to 30 MHz High Frequency
VHF band 30 to 300 MHz Very High Frequency
UHF band 300 to 1000 MHz Ultra High Frequency
L band 1 to 2 GHz Long wave
S band 2 to 4 GHz Short wave
C band 4 to 8 GHz Compromise between S and X
X band 8 to 12 GHz Used in WW II for fire control, X for cross (as in crosshair)
Ku band 12 to 18 GHz Kurz-under
K band 18 to 27 GHz German Kurz (short)
Ka band 27 to 40 GHz Kurz-above
V band 40 to 75 GHz
W band 75 to 110 GHz W follows V in the alphabet
mm band 110 to 300 GHz

In one line … Ku, Ka, and C band are different frequency ranges. This means different size antennas called dishes (inside nice white radomes on marine vessel). If you know that 300 / F (mhz) = wavelength in meters You can get an idea of why. C band best example is Big Ugly Dish (BUD) on homes before sat tv industry took off. Then Ku band looks like typical home TV dish before fancy HD on Satellite. Ka fiasco used by DirecTV for addition of HD - creating fiasco for marine because needs multiple Ka, Ku to get regular and HD channels. Higher frequencies used in Ka band may be more subject to “rain fade” loss of signal more than Ku band because of higher frequency and shorter wavelength (smaller antenna size.)
* That was a very long line.

Marine Satellite: Alan Spicer’s Comments re: Inmarsat’s Challenging Transition
4. November 2010 by admin.
* The next article link and quote that I just posted below was interesting from a marine satellite perspective - because …My market is mostly pleasure and charter yachts and sailing vessels. Owners and Captains of these “boats” are always looking for a “fair shake” in the Internet and Voice Communications for their vessels - while trying to have “Always On Internet” for the majority of their communications (Business related to running a boat and Crew Morale by letting the crew keep in touch with their friends and family.)
Once you cross the line between land-based Internet service into Marine Internet service the price jumps from $60 to $100 per month to $1000’s per month. That’s how VSAT is priced. Even when you are looking at Inmarsat Fleet Broadband you can get the same Internet service for a LOT less when it is called BGAN which it is on land. It’s so bad that I’ve heard of boats carrying BGAN portable units on a boat to save both the cost of the marine satellite system installation and the cost of usage.The Inmarsat … world famous for having done the Fleet 33 / 55 / and 77 for the last few years (where you pay per Megabit or per Minute) and more recently the Fleet Broadband which also has per usage charges that are quite high and monthly fees (on some plans?) that are also quite high.
Others… which I will not name have offered VSAT or Small-VSAT with different cost structures. You pretty much have to follow all of the providers and services to know what’s going on.Inmarsat puts up their own satellites … huge very costly satellites … the size of an English Double-Decker bus and has to maintain those satellites and related network infrastructure. So Inmarsat has to make back all of the initial costs of building the birds, launching them, setting up the infrastructure on land to support them, etc. etc. *Others lease “transponders” on satellites maintained by others - perhaps saving some costs in the deployment and maintenance of the satellite infrastructure. They might still have to provide earth stations and land infrastructure to support their service via these leased transponders - but that’s got to be a lot less than what Inmarsat has to deal with.If you were one of the other guys … trying to find satellites in all the right geographic locations to be able provide service to marine vessels everywhere that you want to cover - has got to be very difficult and no doubt costly as well. So both plans have to recoup these costs and try to provide the best reliable service for every customer wherever they may roam in their ship or boat.
There are also different bands being used for providing satellite service. The old C-band - is what Satellite Television Providers use to provide the service to resellers - Cable Television Companies. But when it got interesting was when Ku-band became available. You will see that both Satellite TV and Marine Satellite Internet grew following Ku-band being implemented. Now, as you see also in Satellite TV, Marine Satellite Internet wants to go to Ka-band as well. You will see Ka-band mentioned with the new Inmarsat 5 as well. But those nice letters also equate to Frequency bands. Higher and Higher frequencies being used. As we know from radio when the frequency gets higher the wavelength gets shorter - hence the smaller antennas. If you have satellite tv like I do you may know what “rain fade” is. When it rains sufficiently hard the higher bands go out first. I lose HDTV when it rains and have to switch to Standard Def. TV Channels when “rain fade” kills my HDTV channels. That’s my only choice. Either be down or switch to Ku-band for Standard Def. TV and keep on watching. The same kind of thing is mentioned with the Inmarsat 5 new system … how well will it handle “rain fade” and other reliability issues?
* Well that’s it for now. I just wanted to shoot some comments out there related to the article. If anyone has better information or knowledge than I do - I welcome any comments.

Marine Satellite: Inmarsat’s Challenging Transition (SatMagazine)
4. November 2010 by admin.
http://www.satmagazine.com/cgi-bin/display_article.cgi?number=1924997957
Marine Satellite: Inmarsat’s Challenging Transition (SatMagazine)
Beam… Inmarsat’s Challenging Transition
author: Alan Gottlieb, Managing Director, Gottlieb International Group, Inc.
For Inmarsat, the move into the maritime VSAT world is a leap far beyond the scope of a difficult technological transition. The Company’s bold move will require a re-make of its traditional business and financial structure. To be successful, Inmarsat must morph from a traditional communications provider that sells by the byte and by the minute to a solutions provider skilled in systems integration and consultative selling. This challenge, if properly met, will insure Inmarsat’s dominance in the maritime communications world, or if unmet, could relegate the Company to the ranks of other corporate giants who missed a critical turn in the market…and are no more.
The Rush To Fixed Priced Broadband
From nearly no market penetration three years ago to more than 5,000 installations today, VSAT adoption continues to grow dramatically. In Inmarsat’s core heavy user market, the shift to VSAT continues to accelerate.To its credit, Inmarsat has achieved some success by defending its position through aggressive discounting of it FleetBroadband service and a novel-pricing plan called SCAP (Shared Corporate Access Plan), directed specifically at the large fleet market. Under SCAP, owners with 50 or more vessels and ready to commit to three year contracts can reportedly buy packages of 2 to 5 Gigabytes per/month for as little as $1 per/Megabyte. The implementation of if the SCAP combined with the recession has helped Inmarsat – especially in the Containership segment.
The Plan has been especially effective because the high price of a 1.2 Meter VSAT Antenna ($60,000 or more) has been difficult to justify during the severe downturn in container shipping — purchasing FleetBroadband makes sense as a first step when acquiring a hybrid L/Ku-band service (as it is required anyway as a VSAT back up). However, despite the aggressive marketing of FleetBroadband and the SCAP, major operators have conducted numerous VSAT trials, and a significant move to the technology in the Containership sector is expected as economic conditions normalize.
In the Tanker segment, Teekay Shipping, Frontline and Tsakos Tankers are recent purchasers of major VSAT systems. With demand for more than 50 Gigabytes per/month per ship of data, Rob Morrison, Teekay’s IT Manager for Europe, notes at the recent Digital Ship Conference in Stamford that FleetBroadband is, simply put, economically impractical. Tsakos, one of the largest Greek Tanker operators and a leader in new technology adoption has 2.4 Meter C-band Systems installed on 17 of its vessels — Eletson, one of the largest product tanker companies, plans to install VSAT within the next 18 months. With the adoption of VSAT spreading, the pressure for Inmarsat to react has intensified.
Inmarsat Responds
In August, Inmarsat stunned the Maritime VSAT community by announcing its answer to the Ku- VSAT threat, the Global Xpress service, a high capacity Ka-band service billed to deliver speeds up to 50 Megabits per/second to antennas as small as 20 cm. According to Andrew Sukawaty, CEO of Inmarsat, the move to Ka- was justified by limited Ku- availability.
While Sukawaty’s logic seems inescapable — lack of capacity in Ku-, the use of the proposed Ka- infrastructure raises significant technological questions regarding the ability of the narrow beam structure to support services with Committed Information Rate Service (CIR). CIR is a feature often demanded by large fleets of sophisticated users. Ka-’s ability to deliver “always on” service, especially under Rain Fade conditions, is also in question.
The advanced infrastructure of the Boeing 702 HP satellites and state-of-the-art coding and modulation techniques are likely to mitigate the technical issues associated with the new I5 Service, no one knows for sure how the service will actually perform under tropical rain. Unlike FleetBroadband with its verified L-band performance, trials will almost certainly be required to prove Ka’s viability in a monsoon or heavy rain environment. While reaction to the proposed service, so far, has focused largely on these sorts of technical issues, the business and financial issues associated with the new Global Xpress services offer daunting challenges as well.
Needed — A New Business Model
The need to re-make the Inmarsat business model to accommodate Global Xpress has profound implications to the Company itself and its reseller network. The entire marketing and sales structure will need to be altered, sales personnel will need to be retrained or replaced, and there will be severe affects on the cash flow of both Inmarsat and its resellers.In the conventional Inmarsat business model, services are offered either by the byte or by the minute. Customers know what they are buying; the sale cycle is short; selling expense is low, and cash flow is realized in the short term. The VSAT business environment is substantially different.

SpaceX… When You Drop A Dragon In Space Make Sure It Has A Parachute! (Spacecraft) - [SatNews] It’s always important to make sure your parachute works properly, whether golden or otherwise.
2. September 2010 by admin.
* This looks reminiscent of the US NASA Apollo Space Program … with a space craft designed to drop back down from space and deploy parachutes for a water recovery landing.
http://www.satnews.com/cgi-bin/story.cgi?number=886061620
Today SpaceX (Space Exploration Technologies) announced their Dragon spacecraft has successfully completed a high altitude drop test, meeting 100 percent of test objectives. This is the last in a series of tests to validate parachute deployment systems and recovery operations before the craft’s first launch.
During the August 12th test, an Erikson S-64F Air-Crane helicopter dropped a test article of the Dragon spacecraft from a height of 14,000 feet, roughly nine miles off the coast of Morro Bay, California. In a carefully timed sequence of events, dual redundant drogue parachutes deployed first to stabilize and gently slow the craft before three main parachutes, 116 feet in diameter, further slowed the craft to a picture perfect landing. From there, recovery ships successfully returned the Dragon and parachutes to shore.
While Dragon will initially be used to transport cargo, the spacecraft was designed to transport crew and the parachute system validated during the test is the same system that would be used on a crew-carrying Dragon.

ESA… GOCe Glitch (SATCOM) - [SatNews] Another major satellite has experienced difficulties, this one in the form of a software glitch.
2. September 2010 by admin.
* Satellite needs a reboot? A Windows Update? Well sort of … And you think your computer has problems? Imagine if it was out in space? and you couldn’t just call Alan Spicer to fix it!
http://www.satnews.com/cgi-bin/story.cgi?number=1593012507
The European Space Agency has reported the GOCe satellite has been troubled with such a difficulty since July. GOCe is designed to map the gravitational field of Earth, but has been unable to send its collected data to receiving stations. A patch is currently being worked on to correct the telemetry problem and the hopes are for a radio link to be installed by next month. GOCe has already completed two-thirds of its mission, with many of its science objectives already completed. The satellite was launched on March 17th in 2009.
The ESA describes GOCE as “the Formula 1″ of satellites due to its avant-garde design — it is a five-metre (16.25-feet) craft that is arrow-like in appearance, rather than the usual boxy dimensions. The satellite possesses stabilizing fins as it orbits Earth at an altitude of just 250 kilometres (156 miles) where there is still a lingering atmosphere. This is not the first difficulty for GOCe, which actually had a primary computer chip failure in February of this year. This required a switch over to the backup computer.
