Product overview
The SIYI RTK Positioning & Orientation Module combines satellite positioning and dual-antenna direction finding in a single module for drone navigation. Its receiver supports GPS, GLONASS, Beidou, Galileo and QZSS, alongside a PNI RM3100 electronic compass. The direction-finding configuration uses two antennas connected to one module, with an orientation accuracy of 0.2 degree at a 1 meter antenna baseline. Positioning accuracy is specified as 0.8 cm + 1 PPM horizontally and 1.5 cm + 1 PPM in elevation; single-point positioning accuracy is 1.5 m horizontally and 2.5 m in elevation.
The module supports RTCM3.X data and refreshes positioning data at a default rate of 5 Hz, with a maximum of 20 Hz. Connections comprise one UART and I2C interface, an additional UART, USB Type-C and MMCX antenna connectors. Measuring 40 x 30.5 x 15 mm and weighing 22.8 g, it requires a 4.5–5.5 V supply and consumes 1 W. Its specified operating temperature range is -30 to 75 °C, with acquisition times below 30 seconds for a cold start and below 5 seconds for a hot start.
