Autonomous position determination in the Globalstar satellite communication system is discussed. The two-way communication between a user terminal on the earth's surface and a single low earth orbit (LEO) satellite makes it possible to derive range and range-rate and determine the user terminal position instantly. Expected accuracy is presented, and a simple direct solution is given.
