Abstract: Methods for determining corrected positions of a global navigation satellite system (GNSS) rover using a GNSS base station and one or more GNSS reference stations include determining a statistical representation of position measurements from the GNSS reference stations and an instantaneous position measurement from the GNSS reference stations. A position correction is determined based on the statistical representation and the instantaneous position measurement. A corrected position of the GNSS rover is determined based on a position of the GNSS rover and the position correction.

Abstract: A global navigation satellite system (GNSS) receiver including an antenna module configured to removably attach to a receiver module. The antenna module includes an antenna configured to receive wireless signals transmitted by a GNSS satellite. The antenna is coupled to a wired connection. The antenna module also includes an antenna-side radio that is coupled to the wired connection. The antenna-side radio is configured to perform actions including sending, via the wired connection, an identifying signal to a receiver-side radio. The identifying signal includes identification information corresponding to the antenna. The receiver module includes the receiver-side radio coupled to the wired connection. The receiver-side radio is configured to perform operations including receiving, via the wired connection, the identifying signal from the antenna-side radio. The receiver module also includes a radio frequency (RF) front end coupled to the wired connection.

Abstract: Systems and methods for identifying which of a plurality of signal types received by a global navigation satellite system (GNSS) receiver includes a spoofing signal. One method may include, for each particular signal type of the plurality of signal types, excluding the particular signal type, calculating a parameter of a GNSS receiver based on the received wireless signals having a plurality of remaining signal types, and calculating a residual score based on a variability associated with calculating the parameter, the residual score being one of a plurality of residual scores. The method may also include identifying an outlier of the plurality of residual scores and identifying which of the plurality of signal types includes a spoofing signal based on the outlier.
