Embodiment Construction

[0036] The present invention is a high-precision GNSS measurement system realized by a CORS (Continuous Operational Reference System, abbreviated as CORS) base station receiver. The built-in GPS receiving module adopts a high-performance GPS receiving board, and the GLONASS receiving module adopts a high-performance GLONASS receiving board, which has excellent tracking performance. The whole machine is highly sealed, waterproof, dustproof, shockproof, and low power consumption. The overall framework of the CORS base station receiver:

[0037] 1. Overall structure design

[0038] (1) Satellite signal tracking: use mature and reliable GPS receiving modules and GLONASS receiving modules, and provide relevant test data for subsequent processing when it is required to use a matching antenna to receive data.

[0039] (2) Main control unit: figure 1 is the basic composition of the system.

[0040] (3) Data storage part: use a built-in storage space of at least 2G to record data f...

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...
