2021/04/13 SkyTraq’s S2525F8-BD-RTK multi-constellation RTK receiver is designed for UAV and mobile platforms. SkyTraq Technology, a fabless GNSS positioning technology company, is introducing the S2525F8-BD-RTK, a cost-effective, low-power single-frequency RTK receiver for unmanned aerial systems and mobile platforms requiring centimeter-level position accuracy. The S2525F8-BD-RTK multi-constellation RTK receiver supports GPS, BDS, QZSS, and SBAS, simultaneously tracking up to 28 satellites. With its 25 x 25 millimeter form factor, 300-mW power consumption and 3 gram weight, it is designed for any outdoor applications requiring high-precision RTK positioning. S2525F8-BD-RTK supports both base station and rover modes. As a rover, it receives RTCM 3.0 or 3.1 data from a base station, or raw measurements from another S2525F8-BD-RTK receiver serving as base station, and performs carrier phase RTK processing to achieve relative positioning with 1 cm + 1 ppm position accuracy within 10-Km baseline. Its compact evaluation board has serial interface connector supporting direct connection to Ardupilot and Pixhawk autopilots for UAS testing. A Bluetooth 2.1 module is included on-board to simplify outdoor evaluation using Bluetooth-connected smartphone or tablet to receive remote base station data via NTRIP client software over the Internet. S2525F8-BD-RTK engineering sample, datasheet, reference design and evaluation kit will be available in October. Volume production delivery to customer begins in November 2015.
