Publication number: 20150022398Abstract: Whether received positioning signals are target positioning signals is determined accurately. A first code phase difference of a first replica code signal of a positioning signal StA and a second code phase difference of a second replica code signal of a positioning signal StB are acquired. A first pseudorange ?1 is calculated based on the first code phase difference and a second pseudorange ?2 is calculated based on the second code phase difference. An absolute value of a pseudorange difference that is a differential value between the first pseudorange ?1 and the second pseudorange ?2 is calculated. If the absolute value of the pseudorange difference is lower than a threshold, the positioning signals of which codes are currently tracked are determined to be the positioning signals StA and StB from a target positioning satellite. If the absolute value of the pseudorange difference is higher than the threshold, cross-correlation is determined to have occurred.Type: ApplicationFiled: February 5, 2013Publication date: January 22, 2015Inventors: Katsuhisa Yamashina, Hiroyuki Nakao
