A revised overocean multipath propagation and cw tone-ranging flight test experiment specifically designed to accommodate the ATS-5 spin is described. The test program will employ the 1540- to 1660-MHz frequency band and will involve an FAA KC-135 jet airplane, the spinning NASA ATS-5 satellite, and a ground station at the FAA NAFEC facility. Four experimental L-band antennas are designed for installation on the KC-135 a steerable quad helix, a crossed-dipole multipath array, and two low-grain slot dipoles. The ground station and airborne terminal hardware are defined. Detailed measured performance data are given for the antennas and major equipment subsystems. The field test program and analysis of the data acquired are accomplished under phases IV and V of the contract. Author
