Context

  • Follow-up of our conversation in the 4S symposium 
  • Fugro is working on a SDR-based demodulator for a space-based application related to high-accuracy navigation in LEO orbit

  • There are probably some synergies with Fugro's project and potential cooperation in this field

Minutes

FUGRO

  • Surveillance, geophysics,...
  • G4 is a high accuracy positioning system (in the order of cm).
    • Commercial product
    • Next steps: to build it for LEO satellites (SpaceStar)
  • SpaceStar
    • Will collect data from all GNSS stations
    • Satellite architecture
      • L-band demodulator
        • Front-end for L-band signals + GomSpace SDR (3 NanoCom + 1 NanoMind)
        • RX: 23 dBV
        • Baud rate: 600-1200
        • BPSK
        • Omnidirectional antenna
      • GNSS antenna
      • GNSS receiver
      • Fugro software
    • Part of ESA project
      • Partners: Deimos, GomSpace (SDR), University of Notthinggham (GNSS simulator)
      • 1 year left
      • Funding from Norsk Romsenter (følgemidler)
      • Opportunities 2019/2020¨
      • In February 2018: started to get familiar with SDR, signal acquisition and demodulation in GNURadio
      • In the future they want to have the software embedded and in the FPGA

DISCUSSION

  • Fugro asked if we have SDR competence to help them
    • They will receive GomSpace SDR in a couple of months, or maybe in August.
  • Torbjørn suggested that we could fly GomSpace SDR on our mission to test it
  • What would be needed to get attitude determination with their system (to avoid star trackers)? 
    • Probably 3 antennas
  • Passive Reflectometry and Dosimetry (PRETTY)
    • GNSS Reflectometry in 3U
    • Tor Arne knows more?
  • NAVIS2
    • Navigation programme from ESA
    • Initiative for both industry and university
    • Maybe we could take part in it
  • Fugro & SpaceNorway are working together for an IOD mission
