概要
The STSW-GNSS-RTKLIB software platform facilitates the implementation and porting of the real-time kinematics (RTK) library on the STM32 platform, enhancing positioning accuracy and error correction in GNSS/GPS systems.
The current implementation employs the RTK library in rover mode configuration, capturing GNSS data in standalone mode.
The hardware platform is built around the STM32H747I-DISCO board, which features 2 MB of flash memory, 1 MB of RAM, and 256 Mbit of SDRAM.
The availability of external RAM is crucial in this implementation to store the RTK library messages radio technical commission for maritime services (RTCM) received from satellites.
Positioning data is gathered using the X-STM32MP-GNSS1 expansion board, which incorporates the Teseo-LIV3FL module for low-power, multiconstellation GNSS positioning.
A user application accessible via a serial interface allows various configuration and display options for the RTK library.
This application operates under a default RTOS using FreeRTOS™. The rtkserver can be managed with commands such as "start" and "stop," and it provides detailed information on: the current status, the number of available satellites, positioning data, RTCM messages, SNR ratio, and more.
