Satellite systems


Ultra has developed a comprehensive range of fixed, vehicle-based and transportable satellite earth stations and satcom terminals that can be rapidly configured for operation. These operate in the most commonly used frequency bands for satellite communications and are suitable for both defence and civil applications.

Ultra provides a comprehensive range of transportable (fly-away FA series) and vehicle-based (drive-away DA series) antennas. Both series feature the innovative cartridge feed arrangement, allowing them to be quickly configured for operation in C, X, Ku and Ka frequency bands. Both series of antennas are available in a comprehensive range of diameters.

Full motion 3-axis motorisation, combined with Ultra’s STC-100 antenna controller, allows antennas to automatically acquire satellites minutes after deployment. An integral tracking receiver will keep the signal peaked.

Ultra’s MIL-STD-810 and Wideband Global Satcom/Defence Satellite Communications System approved fly-away antennas and systems are rugged, compact, easy to transport and to deploy – with guaranteed compliance to all satellite authority specifications. The FA series of antennas is specifically designed to survive the tough environment of satellite news gathering (SNG), but its highly innovative packaging, with robust, lightweight carbon-fibre construction, has made it the preferred choice for a wide variety of other applications. Today, FA series antennas are in service worldwide for sporting events, emergency data restoration and military/government communications.

Ultra’s drive-away antennas are designed with minimum weight and an ultra-low profile, minimum-drag coefficient construction. This makes them simple to install on most vehicles, without affecting the driving characteristics.

An integrated equipment pod provides a secure mounting position for amplifiers and up-converters. This creates extra space and reduces noise and heat inside the vehicle.

Ultra’s DA-100 antenna is small and light enough to travel as commercial aircraft checked baggage and then install on a vehicle roof-rack, turning it into a rapid-reaction SNG vehicle for breaking news.

Along with Ultra’s satellite communication systems, the Ultra Communicate product line offers a seamless global roaming capability. This enables efficient, resilient and rapidly-deployable communication solutions for man-portable, in-vehicle and maritime applications in both the commercial and defence sectors.

Fixed satellite earth stations

Extending its engineering skills base to fixed earth stations, Ultra can provide fixed antennas from less than 1.0m, to over 9.3m diameter.

A key feature of the smaller antennas is the speed of assembly, which allows on-site work to be kept to a minimum and enables service to start very soon after arrival.

Ultra has qualified its fixed antennas with virtually every satellite operator. Its installation team has worldwide experience of adapting the system to local conditions, providing full turnkey services.

Frequency converters

Ultra manufactures a complete range of up-converters and down-converters to meet virtually any satellite communications requirement.

The compact, fully modular design, fully weather-proof outdoor packaging and the extended operational temperature range, standard on all Ultra products, guarantees high performance in virtually any environment.

Antenna controllers

Ultra’s STC series of antenna controllers is specifically designed for use with fly-away, drive-away and fixed antenna systems, but also with any other motorised antenna with positional feedback.

Comprehensive software features allow antennas to automatically point to up to 99 programmable coordinates. Where satellite inclination is known and programmed into the controller, the software can calculate the actual satellite position, at any time of day, and will accurately point the antenna to its known position, before entering peaking and tracking modes.
