TORGI

Build Status

Tactical Observation of RF GNSS Interference

Collect, store, and display observations and analysis of GPS "fix" availability and quality.

Android 7.0 or higher required; 8.0 recommended. Google Pixel 2 (or Pixel 2 XL) provides Automatic Gain Control data.

Compiled APK (Android app installer)

GNSS observation points are stored in a GeoPackage file with satellite and receiver clock details using the (proposed) Related Tables Extension and the NGA GeoPackage Android SDK.

Observation points and associated location fix data are stored as a feature layer within a standard (v1.2) GeoPackage. The Data Model diagram below shows Satellite measurement data and receiver (hardware) clock information tables and their relationships, as currently implemented in the TORGI app.

The Related Tables Extension is a community standard extension to the GeoPackage map database, moving toward full adoption by OGC (Open Geospatial Consortium).
