SYSTEM AND METHOD TO SYNCHRONIZE ACROSS POSITIONING RECEIVERS FOR SECONDARY CODE ACQUISITION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18220729 titled 'SYSTEM AND METHOD TO SYNCHRONIZE ACROSS POSITIONING RECEIVERS FOR SECONDARY CODE ACQUISITION
Simplified Explanation
The patent application describes a receiver device that can accurately determine its geographic position using signals from Global Navigation Satellite Systems (GNSS) satellites. The device includes two antennas, two receivers, and processing circuitry to remove secondary codes from the received signals and perform coherent integration to output the geographic position.
- The receiver device includes a first antenna and a second antenna for receiving signals from GNSS satellites.
- The first receiver is coupled to the first antenna and receives a first signal from a GNSS satellite.
- The second receiver is coupled to the second antenna and receives a second signal indicative of a secondary code boundary.
- The processing circuitry removes the secondary code from the first signal, performs coherent integration on the primary code, and outputs the geographic position of the receiver device.

Original Abstract Submitted
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.
