ArduSimple's simpleRTK2Blite basic starter kit is the lightest multiband GNSS board in the market (7.8g only). Based on u-blox ZED-F9P module, it can work as a standalone product to provide cm level precision or as moving base in combination with the simpleRTK2B board to provide extremely accurate heading.
About RTK GPS Solutions:
Real-time kinematic (RTK) positioning is a satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems (global navigation satellite systems,GNSS) such as GPS, GLONASS, Galileo, and BeiDou. It uses measurements of the phase of the signal's carrier wave in addition to the information content of the signal and relies on a single reference station or interpolated virtual station to provide real-time corrections, providing up to centimeter-level accuracy. With reference to GPS in particular, the system is commonly referred to as carrier-phase enhancement, or CPGPS. Applications include land survey, hydrographic survey, and in unmanned aerial vehicle navigation.
