Title:
POSITIONING METHOD AND POSITIONING TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/240240
Kind Code:
A1
Abstract:
This positioning terminal identifies, as appropriate, a satellite to be excluded, thereby improving positioning accuracy. In ST504, a processor (201) acquires a signal-to-noise ratio (SNR) and an angle of elevation for each satellite. Next, in ST505, the processor (201) identifies a satellite for which the SNR is less than a shielding SNR mask as a multipath satellite and selects this satellite to be excluded. Next, in ST506, the processor (201) generates positioning terminal positioning data using a positioning signal from satellites other than the satellite to be excluded. Next, in ST507, the processor (201) uses reference station positioning data and positioning terminal positioning data of the selected satellite to execute an RTK operation.
