VHF ranging and position fixing experiment using ATS satellites: Executive summary of final report on phases 1 and 2, 25 November - 1 May 1971
The VHF transponders of the ATS-1 and ATS-3 geostationary satellites were used in ranging and position fixing experiments. An interrogation signal was transmitted from a ground terminal to ATS-3, which relayed it to the vehicle transponders. The vehicle that was addressed repeated the signal and its response was relayed back through both satellites to the ground terminal, where propagation times were measured; lines-of-position and fixes were computed. The 0.43 second tone-code ranging signal contained a single audio tone frequency. Ambiguity was resolved and user craft identified by a simple digital code. Seven vehicles were used in the test: three aircraft, two ships, an oceanographic buoy, and a truck. Ionospheric and multipath effects were studied. It is concluded that a VHF system could have an accuracy of + or - one nautical mile for ships and aircraft if calibration transponders are used to monitor the ionosphere.

Shuttle systems evaluation and selection. Volume 1: Executive summary
The major issues affecting the selection of a space shuttle system were considered. These included the HO orbiter/ballistic recoverable booster series-burn configuration; the HO orbiter/ballistic recoverable booster parallel-burn (rocket-assisted orbiter-RAO) configuration; and the HO orbiter/flyback LOX/RP booster configuration. The booster studies emphasized the series-burn ballistic design, but the differences required for RAO application were identified and evaluated. Definition of the RAO configuration parameters and technical problem areas, establishing approaches to possible solutions, and developing program costs are discussed.
