MARINE NAVIGATION AND COMMUNICATION AT L BAND VIA SYNCHRONOUS SATELLITE

The successful conduct of ranging and data tests at L-band with NASA's Application Technology Satellite Number 5 (ATS-5) clearly demonstrated the technological feasibility of accurate and continuous navigation and communication services via synchronous satellite. Applied Information Industries (AII) instrumented the S.S. Manhattan with an ORION receiver and performed a series of tests and experiments during April 1970. These tests started at Newport News, Virginia, and ended in the Northern Baffin Bay region of the Arctic. A similar receiver, set up at AII laboratories in Moorestown, New Jersey, was operated simultaneously with the ship receiver with an additional capability of being able to receive data communications. Using an ORION modulator driving an L-band transmitter and antenna, appropriately modulated signals were originated at NASA's Mojave Station at Barstow, California. Navigation and data communications were transmitted from Mojave, transponded by the ATS-5 satellite and received both aboard the S.S. Manhattan and at AII's laboratories. The course of the ship during the test period gave rise to wide variations in geometry and environment providing an excellent experimental setup to evaluate the system under operational conditions.
