Instant Active Positioning with One

  title={Instant Active Positioning with One},
  author={Nadav Levanon},
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. INTRODUCTION Globalstar 1 is a satellite communication system designed to provide voice and low-rate data… CONTINUE READING
