Title:
GNSS受信方法、GNSS受信機およびGNSS受信システム
Document Type and Number:
Japanese Patent JP4634639
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reposition rapidly by determining a bias value of a 1/2 cycle rapidly even when a situation such as disruption of reception of a satellite signal or the like occurs. SOLUTION: A reference station receiver 31 including a received signal processing part 14a for obtaining navigation data and carrier wave phase data of a GPS satellite from a signal received by a first GPS antenna 13a, and outputting them as first navigation data and first carrier wave phase data of the GPS satellite, and an observation station receiver 32 including a reference station data receiving part 17 for obtaining navigation data and carrier wave phase data of the GPS satellite from a signal received by a second GPS antenna 13b, holding them as second navigation data and second carrier wave phase data of the GPS satellite, and performing a positioning process, and an operation part 38b. The operation part 38b compares the first navigation data and the second navigation data, and determines the bias value of a 1/2 cycle unit with respect to a phase difference between the first and second GPS antennas 13a, 13b.
