GP-Probe DIN L1
DIN L1 GNSS Interference Monitoring for Reliable Network Synchronization
The DIN L1 is a compact, high-performance GNSS monitoring probe designed to detect, classify, and respond to GNSS L1 interference before it impacts your network. Built for telecom operators and critical infrastructure providers, it protects synchronization systems from jamming, spoofing, and signal degradation—ensuring timing accuracy and operational resilience.
Installed inline between your GNSS antenna and receiver, the DIN L1 delivers real-time signal intelligence and automated protection to keep your infrastructure running smoothly.
Why DIN L1 Matters
GNSS disruptions can lead to synchronization failures, service outages, and costly downtime. The DIN L1 provides continuous monitoring and instant alerts so you can act before issues escalate.
Key advantages:
Real-time GNSS L1 interference detection and classification
Protection against spoofing and jamming attacks
Continuous PPS accuracy monitoring
Inline RF switching to block compromised signals
Local processing with optional cloud-based monitoring
Built-In Protection for Critical Systems
The DIN L1 includes an integrated GNSS RF switch that automatically disables output when interference or anomalies are detected. This prevents corrupted or fake signals from reaching sensitive timing equipment.
Result: stronger network resilience, reduced risk, and improved service continuity.
PPS Accuracy You Can Trust
With its built-in PPS Phase Measurement Unit, the DIN L1 continuously tracks timing performance and provides real-time alerts if accuracy degrades—helping operators maintain compliance and avoid synchronization failures.
Smart Monitoring, Cloud or Standalone
The DIN L1 can operate independently or integrate with GP-Cloud for centralized visibility across multiple sites. Onboard processing ensures reliable detection even in secure or remote environments.

Software Options
Subscription to GP-Cloud
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. Get In Touch.
GP-Probe DIN L1 opt.: LUA
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. Get In Touch.
GP-Probe DIN L1 opt.: OSP
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. Get In Touch.
GP-Probe DIN L1 opt.: STREAM
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. Get In Touch.
