Abstract
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.
Claims4
A GPS receiver comprising:
- a first correlating section that synchronously acquires GPS satellites by software correlating;
- and
- a second correlating section that includes a plurality of hardware units that execute a correlating process for tracking the GPS satellites acquired by the first correlating section.
