Overview
- This is a general GNSS module which supports Multi-GNSS systems:
- GPS, BDS, and QZSS, with advantages such as fast positioning, high accuracy, low power consumption, and so on.
Features
- Supports GPS, Beidou (BDS), GLONASS and QZSS multiple satellite systems
- Built-in Low Noise Amplifier (LNA) to Improve Receive Sensitivity
- Built-in Surface Acoustic Filter (SAW Filter) for enhanced noise cancellation performance
- Support AGNSS function
- Support 1PPS function
- UART communication baudrate: 4800~115200bps (9600bps by default)
- Onboard rechargeable Li battery MS621FE, for preserving ephemeris information and hot starts
- 2x LEDs for indicating the module working status
- Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)
