Key Features

GP-Cloud is specifically engineered to process data from our GP-Probe, enabling real-time interference monitoring of GNSS-dependent critical infrastructure. It allows for the connectivity of RTK base stations via RTCM@NTRIP and other GNSS receivers through NMEA@NTRIP, providing instant notifications of detected anomalies. Users can conduct detailed post-analysis of recorded incidents to develop effective countermeasures against GNSS spoofing and jamming.

GNSS Anomalies Detection

The app detects anomalies in raw GNSS data and provides real-time notifications to the user. It supports 1Hz data from a stationary GNSS receiver using protocols such as RTCM, NMEA, and Septentrio SBF.

Interference Classification

Integrated with the GP-Probe, GP-Cloud delivers high-precision detection and classification of intricate spoofing attacks. Assess its performance with our detailed JammerTest2023 report.

Enterprise-grade application

GPSPATRON team has applied the most advanced software tools for real-time operation under high-load. GP-Cloud is ready for data processing on a nation-wide scale.

GNSS Quality Monitoring

GP-Cloud estimates time/position accuracy and calculates GNSS signal quality metrics for each constellation individually.

Data Logging

The GP-Cloud stores in the database dozens of parameters of all visible satellites: pseudorange, carrier phase, Doppler, residual, CN0, DOPs, satellite position, accuracy, quality, spoofing\jamming probability, etc.


Powerful API with documentation in Swagger allows you to integrate the solution in an existing infrastructure.
