Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of GNSS receiver, in particular to a geodetic GNSS receiver device. BACKGROUND

[0002] A global navigation satellite system receiver (GNSS receiver) is a device used to acquire global positioning satellite system (GNSS) signals and determine the position of the receiver. GNSS receivers can simultaneously receive signals from different GNSS satellite systems (such as GPS, GLONASS, Galileo, Beidou, etc.) to improve positioning accuracy and coverage. The working principle of GNSS receiver is to receive signals from satellites and determine the position of the receiver by calculating the propagation time and distance of the signals. The receiver needs to receive signals from at least three satellites to perform two-dimensional positioning (longitude and latitude), and receiving signals from four or more satellites can perform three-dimensional positioning (longitude, latitude and altitude). In practical applications, GNSS receivers are widely used in aviation, navigation, surveying, agriculture, transportation and other fields. In the field of aviation and navigation, GNSS receivers are used for flight navigation, ship positioning, etc., to improve navigation accuracy and safety. In the field of surveying and geographic information systems, GNSS receivers can provide high-precision position information for map making, spatial data collection, etc.
