Abstract

A measurement campaign is presented for high data rate satellite services at EHF-band. A land mobile terminal in a vehicle probes the received signal from an aircraft emulating the satellite. A high-gain antenna with a beamwidth of 25° is used for reception. The antenna is controlled by a GPS-based steering processor. Dual narrowband as well as wideband measurements can be performed simultaneously using independent antennas and receiver equipment. Results are presented showing the tracking performance. A comparison of narrowband signals using either an omni-directional or a steered high-gain antenna is given, and the wideband characteristics of the LMS channel are illustrated
