RT-Base S

A portable and weatherproof base station for GNSS corrections.

The RT-Base S improves data accuracy by transmitting differential corrections (DGNSS) to your inertial navigation systems.


  • Configurable in less than five minutes

  • Internal battery provides a minimum of 24 hours of continuous operation

  • Operational in all weather conditions

  • Large number of DGNSS correction formats to choose from

  • Average position data calculated over a wide user-defined time period

  • Internally logs corrections for post-processing in case radio link is lost


  • Any scenario where real-time RTK integer accuracy is required

Ready to go in less than five minutes
The RT-Base S takes less than five minutes to set up. All the parts you need are in one box. Just place the antenna on the tripod and attach it to the RT-Base S connector, attach the radio modem and you’re ready to go. Once switched on, the RT-Base S automatically computes an average position and begins transmitting DGNSS corrections so you can achieve RTK integer accuracy.


Save positions for repeat use
The RT-Base S can save it’s calculated position for later use. This saves you time if you return to the same position for data collection. It’s important that you place the antenna in exactly the same position each time. When returning to frequently used locations often, this removes the chance of the averaged position changing and ensures measurements captured over several visits are always consistent.


Operational in all conditions
The RT-Base S is IP65 rated meaning it can be left working in all weathers. The internal battery life will provide you with a minimum of 24 hours of continuous operation and with an operating temperature range of -10°C to 50°C it can be used in extreme test locations.

Works with almost any GNSS receiver
The RT-Base S transmits corrections in a number of popular formats such as RTCA, RTCA2, RTCM, RTCM3, CMR and CMR+. This ensures the RT-Base S is compatible with OxTS products as well as many other types of GNSS receiver.

This means you only need to set up one base station when conducting tests with different types of measurement systems.


Disaster recovery
Any GNSS receiver can only maintain RTK integer accuracy as long as it’s receiving differential corrections. As well as transmitting corrections, the RT-Base-S also logs them internally for later retrieval.

This means that in worst case scenarios, if something happens during a test, you can simply download the corrections and apply them in post-processing rather than repeating a test and wasting hours of your time.
