Abstract: INTRODUCTION THE OMEGA POSITION Location Experiment (OPLE) sponsored by NASA/GSFC and illustrated in Fig. 1, includes a synchronous satellite (ATS-3) as a high altitude radio relay whose line of sight coverage includes about 3/3rd of the earth’s surface. Omega VLF navigation signals are intercepted by a Platform Electronics Package (PEP) which can be any place on or above (up to about 50 miles) the earth’s surface. The VLF signals are up-converted to a VHF frequency, transmitted to the satellite, and relayed to the Operational Control Center for analysis. Additionally, a telemeter capability is included, which in the OPLE experiment, multiplex eight typical IRIG sensors, and converted each sensor output into an 8-bit digital word. Details on this system were presented at the National Telemetry Conference 1968, and published in the Proceedings.
