Abstract

The invention discloses a multimode multi-frequency CORS standard reference station based on the ARM9. The multimode multi-frequency CORS standard reference station based on the ARM9 comprises an ARM9 control module and other functional modules. Satellite electromagnetic wave signals are captured by a GNSS antenna, a mimic input signal is provided for a work dividing module, and the work dividing module inputs a GNSS signal to a big dipper module and a GPS / GLONASS module. An SDRAM module is a memory space for the start of a system and execution of a program, a storage module stores a file system and satellite original observation data, a clock module provides an ARM9 control module clock signal, the ARM9 control module processes GNSS data and the GNSS data are sent to a CORS data center server through an Ethernet communication module. The multimode multi-frequency CORS standard reference station can follow real-time satellite data information of eight frequency points of three systems of a big dipper-B1 / B2 / B3, a GPS-L1 / L2 / L5 and a GLONASS-L1 / L2, an autonomous management and network management mode is provided, and a stable and reliable data source is provided for a CORS data center.

Description

technical field [0001] The present invention relates to the technical field of multi-mode and multi-frequency CORS (Continuous Operational Reference System, Continuous Operational Satellite Positioning Service Comprehensive System) high-precision location service, and in particular to a multi-mode multi-mode multi-mode multi-command system based on ARM9 (Advanced RISC Machines, advanced simplified instruction set machine). Frequency CORS Reference Station. Background technique [0002] In precise measurement applications, there are high requirements for the accuracy, accuracy, and timeliness of positioning coordinate data. However, relying solely on remote sensing images is difficult to meet the realistic needs of high-precision acquisition and rapid update. Using the CORS system can make up for the problems existing in remote sensing images, and can greatly improve the real-time accuracy of measurement. [0003] The continuous operation satellite positioning and navigatio...
