Abstract: GNSS receivers are required to be capable of receiving weak signals to satisfy indoor Applications. When detecting weak signals, the receiver may falsely acquire or track the cross correlation peaks of strong signals due to the cross correlation inter ference. Coherent and non coherent in...

GNSS noise can affect receivers with weak signal filtering. For example, on one marine vessel, the GNSS receiver became inoperable in StavangerHarbor, Norway, due to exposure to a 1km away radio line transmitter operating at 1533.005MHz.
OSNMA is one component of a vast array of technologies that protect GNSS receivers from interference. Both jamming and spoofing are a type of radio interference, which happen when weak GNSS signals are overpowered by stronger radio signals on the same frequency. Jamming is a kind of “white no...
