GP-Probe Nano L1 is a highly compact and portable GNSS jamming detector engineered for the identification and logging of interference within the GPS L1 band. It can function independently or in combination with an Android phone via a USB Type-C connection.
The small form factor, roughly the size of a flash drive, makes it ideal for field use, security applications, and interference investigations.
The GP-Probe Nano L1 seamlessly integrates with GP-Cloud, our web application designed for real-time GNSS signal quality analysis, interference detection, and classification. Through the Android application, power measurements from the detector are continuously transmitted to GP-Cloud along with GNSS data from the smartphone’s built-in receiver.
This integration enhances the device's capabilities, enabling synchronized real-time analysis of interference events, precise localization, and post-event forensic investigations.
Use Case Scenarios:
