GPS receiver using software correlation for acquisition and hardware correlation for tracking |
摘要 |
A GPS receiver includes a CPU for synchronously acquiring the GPS satellites by using software correlating and a hardware section composed of multiple hardware correlating units that execute a correlating process for tracking the GPS satellites synchronously acquired by the CPU. Increase in a product size due to tracking can be thereby suppressed in the GPS receiver that synchronously acquires the GPS satellites by the software correlating.
