Software Options
With GP-Cloud, you can monitor all your connected GP-Probes in real-time, receive notifications of detected events, and log all data for post-analysis. Learn more.
Onboard signal processing software option for interference and anomaly detection in GNSS signals without connecting to the GP-Cloud servers. The probe operates completely independently. Learn more.
The software option allows you to create custom LUA scenarios for controlling remote equipment via RS232. It includes a built-in LUA interpreter and debugger. Upon detecting interference, a tailored reaction scenario will be automatically executed. Learn more.
This software option is designed for those who want to integrate GP-Probe DIN L1 into their own spoofing and jamming detection systems and develop custom detection algorithms. It enables streaming of raw GNSS data via websocket and allows saving all raw and processed data on a computer disk for further post-analysis. Learn more.
