GNSS receiver to antenna communications

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.
