SYSTEM AND METHOD TO SYNCHRONIZE ACROSS POSITIONING RECEIVERS FOR SECONDARY CODE ACQUISITION

A receiver device includes a first antenna, a second antenna, a first receiver, a second receiver, and processing circuitry. The first receiver is coupled to the first antenna and configured to receive a first signal from a Global Navigation Satellite System (GNSS) satellite via the first antenna. T...

Beschreibung
Zusammenfassung:	A receiver device includes a first antenna, a second antenna, a first receiver, a second receiver, and processing circuitry. The first receiver is coupled to the first antenna and configured to receive a first signal from a Global Navigation Satellite System (GNSS) satellite via the first antenna. The second receiver is coupled to the second antenna and configured to receive a second signal indicative of a secondary code boundary corresponding to a secondary code in the first signal from a second receiver device via the second antenna. The processing circuitry is configured to receive a primary code by removing the secondary code from the first signal based on the secondary code boundary, perform coherent integration on the primary code, and output a geographic position of the receiver device based on the coherent integration.
