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 number of occultations per day, determined by:
    • how many GNSS systems are exploited (GPS, GLONASS, Galileo, Beidou)
    • whether occultations are exploited with the GNSS satellite rising and/or setting (viewing fore- and/or aft-);
    • whether the instrument is launched and operated as a constellation or an individual system ;
  • the capability to scan the ionosphere (this requires GNSS signal sampling for altitudes above 100 km.

 Sorting criteria and colour code:

  1. Receivers flown on dedicated satellite clusters to track >=3 GNSS systems by 2 directional antennas for both fore- and aft- occultations.  Altitude scanned up to the ionosphere OR not.
  2. Receivers flown on dedicated satellite clusters to track >=1 GNSS systems by 2 directional antennas for both fore- and aft- occultations.  Altitude scanned up to the ionosphere OR not.
  3. Receiver hosted on single satellites, to track >=3 OR >=2 GNSS systems by 2 directional antennas for both fore- and aft- occultations.  Altitude scanned up to the ionosphere OR not.
  4. Receiver hosted on single satellites to track 1 GNSS system by 2 directional antennas for both fore- and aft- occultations.  Altitude scanned up to the ionosphere OR not.
  5. Receiver hosted on single satellites to track 1 GNSS system by 1 directional antenna for either fore- or aft- occultation. OR receiver equipped by only the omni-directional antenna.  Altitude scanned up to the ionosphere OR not.
