Problems solved by technology

[0003] With the rapid development of marine economy, GNSS RTK technology, which can only be used on land and offshore, can no longer meet the needs of marine operations
It is also urgent to use GNSS RTK differential positioning technology when performing positioning and surveying operations in remote sea areas. The traditional GNSS RTK technology establishes the base station on land with a fixed position. Due to the limitation of the working distance between the rover station and the reference station, the rover station cannot be far away from the coast. do homework

Abstract

The invention, which belongs to the measuring method technology field, relates to a real-time difference measuring apparatus for a regular moving boat-carrying base station and a working method thereof. According to the method, on the condition of a static state of a boat-carrying GNSS base station, a long-time positioning operation is carried out and an accurate initial position of the base station is obtained; a moving regularity of the boat-carrying GNSS base station is determined according to a position relation of between a target working area of the boat-carrying GNSS base station and atarget working area of an RTK flow station; and at the same time, an observation speed, a predetermined speed and driving time of the base station are processed, a track error of the base station is calculated and decided, and a driving state of the boat-carrying GNSS base station is also adjusted. In the case of determination of a speed and a starting position of a course of the boat-carrying GNSS base station, an accurate and real-time position of the boat-carrying GNSS base station can be obtained; and a carrier phase difference operation is carried out on range information, carrier information, and navigation message information of the boat-carrying GNSS base station so as to obtain a difference correction number; the difference correction number is sent to the RTK flow station by a data link unit, so that real-time difference measurement of the regular moving boat-carrying base station is completed.

Description

technical field [0001] The invention relates to a real-time differential measurement device for a regularly moving ship-borne reference station and a working method thereof, in particular to GNSS RTK real-time differential positioning and track calculation processing technology, belonging to the technical field of measurement methods. Background technique [0002] GNSS RTK technology is currently the most accurate satellite navigation and positioning method in the world, and people are more and more inclined to use GNSS RTK technology for navigation and positioning measurement operations. [0003] With the rapid development of marine economy, GNSS RTK technology, which can only be used on land and offshore, can no longer meet the needs of marine operations. It is also urgent to use GNSS RTK differential positioning technology when performing positioning and surveying operations in remote sea areas. The traditional GNSS RTK technology establishes the base station on land with...
