Multi-receiver satellite positioning system method and system for improved performance
摘要:
A multi-receiver satellite positioning system (SPS) wireless device (101) and system (100) or method (200) can include a plurality of SPS receivers co-located with each other, and a processor (114). The processor can be coupled to a first SPS receiver (102) and at least a second SPS receiver (104). The processor can be programmed to select (202) a measurement from the first SPS receiver or from at least the second SPS receiver having a desired characteristic, and use (212) the calculated measurement selected for having the desired characteristic for a predetermined application. For example, the processor can select the measurement by comparing (206) a possible error in position (EPE) reported by the first SPS receiver with a possible error in position reported by the at least second SPS receiver and selecting the measurement with the least amount of EPE when accuracy is a desired characteristic.
