Base Station

RT-Base S

A portable and weatherproof base station for GNSS corrections.

The RT-Base is a self-contained unit that includes:

– The Base-Station GPS receiver
– Battery suitable for over 10 hours of operation
– Radio Modem
– Mains Power Supply and Battery Charger
– GPS Antenna, 15m Cable and Tripod
– Radio Modem Aerial, 5m Cable and Magnetic Mount

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.



A quick and easy-touse vehicle mounting system for OxTS GNSS/INS products. Equipment can be mounted securely on the strut in most vehicles in minutes.

Quick to install

The RT-Strut fits between the floor and the roof of the car. A built-in spring provides the necessary force required to keep the RT-Strut in place. Fitting is simply a matter pulling a lever.

Secure multiple products

A number of different brackets mean the RT-Strut can be used to simultaneously mount multiple products. This is particularly useful in automotive ADAS applications where it is often necessary to mount a GNSS/INS product in the car along with an RT-Range S product.

Improved measurement accuracy

Our INS+GNSS products measure the slightest movement with great accuracy. The RT-Strut provides a rigid mount in every axis, so you know you’re measuring the movement of the vehicle – not movement of the product.

Supplementary Retaining Strap System

To improve the safety and security of our RT mounting solutions, the RT-Strut is now comes with a Supplementary Retaining Strap System. This important new safety feature is for use when the RT-Strut is mounted in the vehicle cabin to prevent it moving forwards in the event of a crash. The system attaches to an ISOFix point in the vehicle to ensure stability of the unit during testing. We recommend that the Supplementary Retaining Strap System is used whenever the strut is mounted in the cabin. Full details of installation can be found in the addendum to the manual, which can be download here.

Please note: Your safety is important. It is important that you perform your own risk assessments of any testing you do, in order that you and your colleagues stay safe.
