RTK BASE - Compact, Installed Base Station




Product Datasheet  


The RTK BASE is a multi-constellation GNSS receiver capable of providing RTCM corrections via either a 4G LTE radio modem or via optional radio modem, to give 2cm absolute positional accuracy for a variety of testing applications. The system is designed to work with any of the Race Technology 2cm capable systems, or with any other GNSS receivers which require RTCM V3.x corrections.

The RTK Base will self-survey to give highly accurate absolute position, accurate to just a few mm. The system can be configured to re-survey periodically to account for ground movement. Correction information is only supplied to the server when required by an external unit, so data usage is kept very low. System intialisation takes around 30 hours whilst the current position is recorded and the correct position calculated using a remote service, this is not position averaging. Full status information and satelite information is shown on the LCD.


The RTK BASE is designed for permanent installation and operation. Where portable operation is required look at the RTK BASE Portable.

Using the RTK BASE with the RTK CONNECT and SPEEDBOX-INS or CATS-INS gives all the benefit of the proven speed and attitude accuracy of the SPEEDBOX-INS, with the addition of positional accuracy upgraded from the 1m level to the 2-3cm level. This brings many more applications within the remit of the SPEEDBOX-INS / CATS system, including:

  • Driving robot input
  • Lane deviation testing
  • Target tracking
  • Driver assistance development and end-of-line testing (ADAS)
  • Driverless vehicle research and development


There are ongoing charges for the RTK BASE, they are provided as an all inclusive package, with the first year being free. Extensions to this subscription can be charged either annually or five yearly. SIM cards are user supplied.
