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.

Next is droid phone with chip and apps for surveyors, realestate, construction, etc. phone provides RTK base from CORs etc. Real time centimeter accuracy, plug in car with centimeter GIS and away we go, no driver needed.
