SecRTK - Secure High Precision Position Estimation.
Undisturbed GPS.
When using satellites for navigation, the precise determination of the position is of crucial importance. GNSS (“Global Navigation Satellite System”) receivers are usually used for this purpose, which enable worldwide positioning with great accuracy. However, these receivers are susceptible to interference, which is a massive problem.
Our innovation offers the solution here: the combination of RTK receiver and multi-antenna unit, which is connected as a device in front of the conventional GNSS receiver. While the RTK technology offers high accuracy, interference signals are filtered out by the multi-antenna receiver. It also estimates the direction of the satellite signals. The result is reliable and precise positioning in the centimeter range - without disturbance.
So if you're in trouble with a jammer, no matter if in the Baltic Sea or elsewhere - contact us!
Interference-free.
By integrating the multi-antenna receiver as a device in front of the conventional GNSS receivers, the use of commercially available GNSS receivers is maintained, while at the same time the interference immunity is significantly increased.
The reliable positioning of motor vehicles, trucks, rail vehicles, ships or drones, for example, can thus be ensured by being able to perform reliable positioning with stable reception.
Adaptable.
The process is designed for GPS signals, but this technological development can be adapted to any frequency band.
In professionally conducted test drives under real interference conditions (see illustrations), we have already been able to provide impressive proof of its functionality.
We offer interested companies the opportunity to license and further develop the technology in cooperation with us. Together with you as our partner, we are striving for technological and market leadership in the segment of interference resilience for GPS signals.
- Highly accurate positioning in the cm range using RTK
- Interference resilience for GPS signals
- can be combined with conventional GNSS systems
Scientifically founded.
The development took place as part of a grant from the European Space Agency esa through the NAVISP project and was implemented in close cooperation with the Münster / Steinfurt University of Applied Sciences and the IRT of RWTH Aachen University as well as the IDS of RWTH Aachen University.
The process on which this development is based was described by Prof. Dr.-Ing. Götz Caspar Kappen in a scientific paper and published by IEEE.
A challenge of our time.
GPS interference and falsified navigation signals are becoming more and more of a problem. They affect both air and sea traffic.
GPS jamming, the transmission of interfering signals, and GPS spoofing, the falsification or blocking of signals, can pose a serious threat, including to civil aviation. Falsified GPS signals seriously affect flights, as aircraft systems generally work with satellite-based navigation.
The Baltic Sea in particular is affected by jamming transmitters, which leads to restrictions in air traffic. As a result, aircraft are unable to land at airports and have to be diverted.
Although it is mainly aviation that is affected by the disruptions, shipping is also increasingly affected by disruptions and obstructions. Jammers can even become a problem for car drivers: GPS positioning is disrupted and interrupted.
Interference prevention measures are urgently needed to restore safety.
