Abstract

The invention provides technology for performing GNSS corrected data transmission and performing area high-precision dynamic positioning on a specific area by means of a PDT (professional digital trunking) channel. The positioning method comprises the following steps of performing real-time acquisition of GNSS observation data through GNSS terminal equipment; performing real-time resolving of theGNSS corrected data by a server according to the received GNSS data flow and transmitting the resolved GNSS corrected data to a data forwarding platform; performing re-coding of the GNSS corrected data by the data forwarding platform and performing real-time transmission to the GNSS terminal equipment which comprises a decoding module and a positioning module; decoding the GNSS corrected data by the decoding module of the GNSS terminal equipment and performing transmission to the positioning module, and performing real-time augmentation resolving by the positioning module according to the received GNSS observation data and the GNSS corrected data, thereby obtaining the position information of the GNSS terminal equipment.

Description
