Full name Precise positioning
Definition Precise positioning systems are not only used for spacecraft control and for the provision of satellite-based navigation services (GNSS), they play also a critical role to support satellite altimetry and gravity field observations.
Relevant instruments and their contribution

The sorting column describes how the instruments, by design, have the potential to contribute to certain pre-determined capabilities, assuming nominal operation of space and ground segments. For this particular capability, instrument performance is considered to be driven by:

  • the different techniques exploited.

 Sorting criteria and colour code:

  1. Radio positioning system.
  2. GNSS receiver.
  3. Satellite equipped by laser retroreflectors.
  4. Star tracker.
