Description

technical field [0001] The invention relates to a geographical position measurement device, especially a device that can use a satellite locator for precise positioning, and can also realize spatial position transmission through accurate measurement of slant distance, horizontal angle and vertical angle, and has synchronous real-time regional measurement data. Processing power, interconnected multi-function positioning measuring instrument that can improve measurement accuracy and work efficiency. Background technique [0002] At present, the Continuous Operational Reference System (abbreviated as CORS) established by using multi-base station network RTK technology has become a hotspot in the development of urban satellite positioning applications. The establishment and application of CORS have effectively promoted urban digitalization, information of construction. According to the accuracy of the application, users of the CORS system can be divided into surveying and engin...

Problems solved by technology

[0003] (1) In areas such as woods, tunnels and high-rise buildings, satellite signals are blocked, and there are blind spots in satellite positioning measurement. Since the satellite locator can only passively give position coordinate information, it does not have autonomous angle measurement, distance measurement and autonomous position. The transmission ability, especially the lack of orientation function, and the inability to obtain the position coordinate information of the blind spot measurement point, restricts the application in engineering support measurement;

[0004] (2) In order to complete a topographic, cadastral mapping or engineering support survey task, multiple satellite locators are often used to operate at the same time. Since each locator can only communicate with the CORS system, communication between satellite locators cannot be achieved , does not have the capability of synchronous real-time processing of regional measurement data and integrated mapping, which limits the optimization of the measurement operation process and the improvement of operation efficiency
