RTK applications require a base and a rover. The base can be 3rd party RTK base station service, or one can easily setup a local RTK base to use in base & rover pair operation using two PX1122R .

By submitting dual-frequency RINEX log file, converted from carrier phase raw measurement log file of a single PX1122R, to online PPP service (OPUS、AUSPOS、CSR-PPP、APPS、GAPS...etc.) one can get absolute accuracy centimeter-precise position result anywhere on Earth without the need of RTK base.

  1. Outstanding product 5 Star Review

    Posted by on 28th May 2020

    This device is simply brilliant. It is new so there are some things to find out but the support is swift and simply second to none.
    Inevitably the product will be ahead of the documentation in some aspects as it is so new and still evolving, but as I said, the support is great. Works for me!
    Highly recommended.
