System and method for ranging a PRN receiver with a PRN composite code
First Claim
1. A method for ranging of a Pseudorandom Noise (PRN) receiver, the method comprising:
- generating, at a PRN transmitting device that includes a processor and wireless transmitter and is in a line-of-sight position with the PRN receiver, at least two component codes;
time shifting, with the processor of the PRN transmitting device, the at least two component codes relative to each other to form time shifted component codes;
wirelessly transmitting, with the PRN transmitting device, the time shifted component codes to the PRN receiver with a predetermined modulation; and
receiving the time shifted component codes with the PRN receiver that includes a PRN receiver processor, and determining a range estimate of the PRN receiver based on a combination of the time shifted component codes with the PRN receiver processor.

Abstract
In accordance with one or more aspects of the present disclosure, a method for ranging of a PRN receiver including generating, at a PRN transmitting device that includes a processor and wireless transmitter and is in a line-of-sight position with the PRN receiver, at least two component codes, time shifting, with the processor of the PRN transmitting device, the at least two component codes relative to each other to form time shifted component codes, wirelessly transmitting, with the PRN transmitting device, the time shifted component codes to the PRN receiver with a predetermined modulation, and receiving the time shifted component codes with the PRN receiver that includes a PRN receiver processor, and determining a range estimate of the PRN receiver based on a combination of the time shifted component codes with the PRN receiver processor.

10. A method for ranging of a Pseudorandom Noise (PRN) receiver, the method comprising:
-
wirelessly receiving time shifted component codes with the PRN receiver having a PRN receiver processor, where the time shifted component codes include at least two component codes that are received substantially simultaneously by the PRN receiver; combining, with the PRN receiver processor, the at least two component codes of the time shifted component codes into a composite code by performing an exclusive OR (XOR) operation on the at least two component codes; and determining a range estimate of the PRN receiver and a PRN transmitting device based on the composite code with the PRN receiver processor. - View Dependent Claims (11, 12, 13, 14, 15)
