Present and final system configuration of the GPS-NAVSTAR and possible applications are reviewed. The pseudo-random noise-sequences (PRN-coding), in combination with Doppler and phase measurements, allow the realization of an extremely precise and flexible system for many kinds of navigation purposes.

The design concept alternatives for GPS-receivers are discussed with respect to the application of

  • One and Two.carrier Receiving Systems
  • One or Multiple Ranging Receiver Channels
  • Analog of Digital Circuitry
  • Ranging Code Information or
  • Only Code and Carrier Information
  • Carrier Phase Extraction.

Actually available GPS-receivers are reviewed.

The various geodetic and geodynamic measurements tasks are shortly discussed in view of applicable measurement configurations.
