SkyTraq Brings A Miniature, Low Power, RTK Receiver Into UAS + Mobile Platform Environments

[Satnews] SkyTraq Technology Inc., a fabless GNSS positioning technology company, has introduced their S2525F8-BD-RTK, a cost effective, low power, small size, single frequency RTK receiver for unmanned aerial systems and mobile platforms requiring centimeter-level position accuracy.

S2525F8-BD-RTK is a multi-constellation GNSS RTK receiver that supports GPS, BDS, QZSS, and SBAS; simultaneously tracks up to 28 satellites. Its 25mm x 25mm form factor, 300mW power consumption, and 3 gram weigh makes it ideal 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 1cm + 1ppm position accuracy within 10Km baseline.

The product's 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.
