Abstract
A positioning apparatus calculates an offset frequency of a local oscillator based on position information which is positioned, satellite position information acquired from a satellite signal of a GPS satellite, and a velocity vector of a GPS satellite. A GLONASS function is operated based on the offset frequency; then, positioning is carried out by the GPS function and the GLONASS function.
Claims7
A positioning apparatus having a GPS function receiving a satellite signal from a GPS satellite and a GLONASS function receiving a satellite signal from a GLONASS satellite,
- the positioning apparatus comprising:
- a local oscillator that generates an oscillated frequency, wherein the GPS function demodulates the satellite signal with the oscillated frequency to execute a positioning, and the GLONASS function demodulates the satellite signal with the oscillated frequency to execute a positioning;
- and
- a positioning computation section that
- computes an offset frequency of the local oscillator based on position information which is positioned, satellite position information acquired from a satellite signal of a GPS satellite, and a velocity vector of a GPS satellite,
- causes the GLONASS function to operate based on the offset frequency, and
- executes a positioning using the GPS function and the GLONASS function.
