• Impact of flex power on GPS Block IIF differential code biases 

      Esenbuğa, Özge GizemORCIDiD; Hauschild, AndréORCIDiD (GPS Solutions, 2020-07-08)
      GPS Block IIF satellites are able to redistribute the transmit power between the signal components. This ability is called flex power, and it has been developed as a remedy against jamming. Since it is operationally not ...
    • Performance assessment of GNSS-based real-time navigation for the Sentinel-6 spacecraft 

      Montenbruck, OliverORCIDiD; Kunzi, FlorianORCIDiD; Hauschild, AndréORCIDiD (GPS Solutions, 2021-11-15)
      The feasibility of precise real-time orbit determination of low earth orbit satellites using onboard GNSS observations is assessed using six months of flight data from the Sentinel-6A mission. Based on offline processing ...
    • Precise point positioning with GPS and Galileo broadcast ephemerides 

      Carlin, LucaORCIDiD; Hauschild, AndréORCIDiD; Montenbruck, OliverORCIDiD (GPS Solutions, 2021-03-27)
      For more than 20 years, precise point positioning (PPP) has been a well-established technique for carrier phase-based navigation. Traditionally, it relies on precise orbit and clock products to achieve accuracies in the ...
