High-precision UM980 module GNSS full-system full-frequency centimeter-level low-power RTK differential starry GPS module

The company's AK314-2 type uses a full-system full-frequency RTK engine and a full-frequency RTK integrated module (hereinafter referred to as the module), which is an ultra-low-cost, low-power, high-performance real-time positioning system. Time dynamic differential positioning module. The module adopts highly reliable carrier phase difference technology, which can provide real-time centimeter-level positioning accuracy for drones, cars, and surveying and mapping users. The module can be configured as a "mobile station" or "base station" working mode. Through the same line-of-sight observation between the "mobile station" and the "base station", the carrier phase difference technology is used to eliminate ephemeris errors, ionospheric errors, tropospheric errors, and inter-satellite errors. Measurement errors such as clock errors, and finally obtain high-precision positioning results. Configured as a "base station" module, the differential interface outputs RTCM2.x/3.x standard data streams, which is compatible with most commercial mobile stations on the market. At the same time, a reference design of network RTK is provided, which can distribute differential data streams to all mobile stations through the network. Configured as a "mobile station" board, the differential interface supports RTCM2.x/3.x differential data format, which can be connected to the user's existing base stations of other brands or connected to the national Beidou ground-based augmentation system. The static relative positioning accuracy of the module is <1cm, the medium dynamic relative positioning accuracy is <2cm, and the output rate is 1~10Hz. It can be applied to a variety of scenarios and has a very high cost performance.

The AK314-2 integrated module has the following characteristics: 1. Based on the UM980 series product design, the module can obtain stable and high-precision positioning results even in harsh environments. 2. Support BeiDou B1I/B2I/B3I/B1C/B2a/B2b + GPS L1/L2/L5 + GLONASS L1/L2 + Galileo E1/ E5a/E5b/E6 + QZSS L1/L2/L5 /L6 + SBAS 3. Support The Beidou/GPS/Galileo/GLONASS four-mode joint RTK solution has fast and reliable initialization capabilities. 4. Support data output up to 50Hz, to meet the application of UAV under dynamic conditions. 5. The module can be flexibly configured as a base station or a mobile station. 6. It supports two modes of differential positioning and vector attitude measurement, and can output high-precision positioning and orientation results at the same time. 7. The built-in four-arm helical antenna combination has the characteristics of light weight, high gain, high precision, and strong anti-interference ability. 8. Adopt industrial-grade low-noise radio frequency circuit, strong anti-multipath suppression ability.
