With K803 Lite(L1) module, the smooth positioning solution can track GPS, BeiDou, GLONASS and Galileo, providing reliable and stable GNSS positioning data.
Taking full advantage of single-frequency GNSS carrier phase and Doppler observation, the K803 Lite (L1) can provide a smooth and accurate trajectory without GNSS correction data input, reaching 15cm pass-to-pass accuracy in single-point mode.
SA100 antenna tracks all constellations including GPS, GLONASS, BeiDou, Galileo & QZSS. With its shock resistance, IP67 protection level, it is ideal for precise agriculture.
K803 Lite (L1) module is a lite version of K803 module, with multi-constellation & single-frequency tracking capabilty and DP-filter algorithm, K803 Lite (L1) provides your a cost-efficient but accurate solution for precise agriculture.
