Mobile Ka-Band Delivers
The new Ka-Band service has promised to deliver unheard of bandwidth speeds, low costs, small antennas and excellent performance. C-COM ask is this fantasy or reality?
The general feeling so far is that fixed Ka systems have delivered on these pledges – but what about in the mobile world? If Ka could deliver these benefits in a fixed location, can a mobile platform deliver the same performance? C-COM Satellite Systems Inc., based in Ottawa, Canada, has a reputation for producing costeffective, highly reliable autopointing satellite antenna systems used in the Ku and C-band spectrum. In order to meet the high accuracy required by Kaband, C-COM had to develop a completely new antenna platform for its commercial customers. Beginning in late 2009, C-COM engineers using leading edge mechanical design techniques started to address the operational requirements for Ka, using little to nothing of the design from their existing legacy Ku systems, which remain very popular and are selling in the thousands worldwide, to this day. The new product would be lightweight, employ an absolute minimum number of parts, utilise a belt drive system (providing “near zero” backlash) and have positive placement control. To provide the base strength required, C-COM invested in new castings, and all of the parts were engineered to deliver the performance mandated by the world’s largest satellite operators (Eutelsat and Viasat). The design required the platform to accept the RF components specified by these operators, and to be able to provide absolute repeatability. The C-COM manufactured iNetVu 7000 Controller would also require a complete overhaul. The existing model provided 12 volts DC with specific tactical input capacity; the new platform would require 24 volts DC with completely new sensory devices. The redesign mandated a new iNetVu 7024 Controller. Not only would the n e w

C-COM’s iNetVu Ka-75V offers a compact footprint

ACU address the mandated operational requirements, but it would also offer the capability to use the Glonass GPS Navigation system, a complement and alternative to the US-based GPS system. New software and firmware would also have to be developed to allow the 7024 to drive the Ka platform accurately, repeatedly and reliably. It was a must for the antenna to meet very rigid testing standards put in place by Eutelsat and Viasat. The unit was then tested in North America using the new Viasat-1 satellite. Following the positive results of such tests, the unit was then taken to Eutelsat’s Teleport in France for operational testing. A number of weeks passed and additional modifications to software and firmware were made. A close working relationship was developed with Eutelsat and many specific features were implemented based on their requests. The iNetVu Ka75V (the model name of the autoacquire antenna compatible with the Viasat/Eutelsat requirements) had the capability of choosing the correct modem configuration based on the physical location at time of deployment. This feature was to be completely automatic; the user only had to press one button to deploy the unit and locate the satellite anywhere coverage existed. RF testing was completed to ensure the unit performed with the operational requirements of

both Eutelsat and the various governments throughout the coverage areas. These tests were done using several different Transceivers. At the end of the exhaustive process, the iNetVu Ka-75V became the first Mobile Antenna System to be fully certified and approved by Eutelsat for use on KA-SAT, allowing it to be deployed anywhere in the extensive coverage areas. At the same time, the antenna was and remains the only approved mobile antenna available for use on the Exede service provided by Viasat in the US.

During the testing process, C-COM worked with a number of dealers who began marketing this exciting new product throughout Europe. Eutelsat realised there would be great demand for the product from the Electronic Satellite News Gathering market, and thus a new reseller group called ‘NewsSpotter’ was developed. This group would be authorised by Eutelsat to sell the new Ka-band service in a mobile environment to companies who would purchase bandwidth ‘On Demand’. Those resellers would need a vehicle based or transportable mobile Ka

solution such as the iNetVu Ka-75V. Trials were started by a number of agencies to test the new Ka service. Those tests proved that the new service was robust enough to handle the demands of video transfer in a truly mobile environment. Trials have been completed in the United Kingdom, Netherlands, Germany and France. Susceptibility to rain fade is one of the disadvantages of Ka-band and has led to some hesitancy in its deployment in the past. One news agency from the United Kingdom tasked to push video from the Diamond Jubilee in early June 2012, thought this would provide a perfect venue to test the mobile Ka-band antenna systems. They deployed an iNetVu Ka-75V unit, in addition to a larger Ku-band antenna, and pushed video through both systems. During the event, the weather proved unpredictable and significant rainfall was encountered. Fortunately, the live feed on the Kaband service never dropped a single time during the event. Obviously, additional testing will be needed to verify Ka-band performance during rainfall, but as the number of agencies using Ka for these application increases, more results will be compiled. So, the answer to the riddle is yes – mobile Ka is a reality and the iNetVu Ka-75V is available for deployment today. ■
