PROBLEM TO BE SOLVED: To improve positioning accuracy and to shorten time required for positioning, related to a positioning device such as GPS receiver. SOLUTION: A plurality of positioning signals transmitted from different satellites are received, the information contained the received positioning signals is demodulated, and the demodulated information is analyzed for positioning current position. Here, a first receiving part (for example, 101-108) wherein the positioning signal from each position is received and processed for each positioning signal and then information is demodulated, and a second receiving part (for example, 109-112) wherein the positioning signal at high elevation angle among positioning signals from satellites is received and processed for demodulating information, are provided. |
