Special receiver for multi-constellation integrated CORS (Continuously Operating Reference Station) and working method thereof

Abstract

The invention provides a special receiver for a multi-constellation integrated CORS (Continuously Operating Reference Station) and a working method thereof. The special receiver comprises a power source function module, a GPS receiving module, a GLONASS receiving module, a CPU, a control circuit module, a memory function module, an external interface module and a network communication module, wherein the power source function module is used for supplying power for the receiver; the GPS receiving module and the GLONASS receiving module are connected with the CPU and the control circuit module; and the CUP and the control circuit module are respectively connected with the memory function module, the external interface module and the network communication module. The invention realizes a high-precision GNSS (Global Navigation Satellite System) measuring system through a CORS receiver; the built-in GPS module adopts a high-performance GPS receiver plate; the GLONASS module adopts a high-performance GLONASS receiver plate; and thus, the invention has the advantages of high tracking performance, high sealing performance of the complete machine, water resistance, dust prevention, vibration resistance and low power consumption.

Description

technical field [0001] The invention relates to a multi-constellation integrated network differential reference station networked digital survey device, which belongs to the technical field of high-precision GNSS measurement systems. Background technique [0002] At present, the technical development status of the Global Navigation Satellite System (GNSS) receiver used for measurement is as follows: [0003] (1) The global navigation satellite system includes the GPS of the United States, and most of the current market still relies on receivers that rely on a single constellation. [0004] (2) The operation unit mainly uses a pair of GPS receivers, one as a base station and the other as a mobile station, and uses the radio station to broadcast differential correction information, and conduct field survey data collection through single base station positioning. The working distance is 10 kilometers, and the positioning accuracy decreases rapidly with the increase of the base...

Problems solved by technology

Moreover, general embedded terminals do not have the function of providing network services

[0005] With the development of multi-constellation navigation systems, users' requirements for compatibility and interoperability between satellite positioning systems are constantly increasing, and a single navigation system can no longer meet people's needs for navigation performance. In the case of interference, it can still use the signals of other constellations to achieve positioning
