NS-HP-GN2 : PX1122R Multi-Band Quad-GNSS RTK Breakout Board


Product Description

NS-HP-GN2 is PX1122R multi-band quad-GNSS RTK receiver OEM module in easy to use breakout board form.     

* 230 Channel Carrier Phase Measurement RTK Receiver
* Hardware Supporting:
  GPS     L1  / L2C
  Galileo E1  / E5b
  Beidou  B1I / B2I
  GLONASS L1  / L2
  QZSS    L1  / L2C
* Integrated RTK, no 3rd party software needed
* 1cm + 1ppm RTK accuracy in seconds
* Fast and reliable performance
* Up to 25Hz RTK update rate
* Base or rover mode configurable
* Precise RTK position and heading using two modules
* Heading accuracy 0.27 / 0.07 deg @ 50 / 200 cm baseline
* Output dual-frequency carrier phase measurement in base mode

* Centimeter-level high precision navigation
* Precision agriculture
* Machine control guidance
* Survey and GIS data collection
* Structure and deformation monitoring
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 NS-HP-GN2, 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.

    I have built and tested a full base - rover GNSS system in only a few days time. Next step will be development towards vehicle guidance.
    Stability and accuracy of this little GNSS are excellent!
