HR Smith Technical Developments have developed a range of Ground Plane Independent SATCOM / GPS Antennas based on their successful series of civil airborne antennas. The antennas have been initially developed for use on smaller aircraft and helicopters and come with the additional benefit that the antenna can potentially replace existing GPS antennas, which reduces the amount of mechanical modification to the aircraft.
The antennas are available with either right hand or left hand polarisation suitable for the Iridium or Thuraya satellite systems, in addition to the GPS capability.
To improve the antenna gain, these high performance antennas use a number of patches and can electronically "steer" nine individually selectable scanning segments for optimal performance dependent on the satellite position. The position of the aircraft is taken from the Flight Management System into the Satellite Transceiver which already has the satellite positions stored in its memory. HR Smith can also offer a Switching Matrix Unit to perform this function, if required. This unit can also perform an automatic scan of the scanning segments to detect the strongest signal and hence "steer" the antenna accordingly.
