Channel sounding flights were conducted at Edwards Air Force base from 1998 to 1999 to quantify the multipath interference in aeronautical telemetry applications. The effort was sponsored by the Advanced Range Telemetry (ARTM) Program. The sounding signal was transmitted from an airborne transmitter and received by a ground station equipped with a parabolic reflector antenna with tracking capability.

The ARTM multipath channel sounding was conducted at L and S band frequencies. The &E S&T program has funded channel sounding activities at 4 and 8 GHz. The channel sounding flights were conducted at Edwards AFB. The sounding signal was transmitted from an airborne transmitter and received by a ground station equipped with a parabolic reflector antenna with tracking capability.
