I was able to play around with the CRFS RFeye nodes recently. Usually, another division of the company handles this, but I was out with former military units I was once a member of.....seeing how this can detect FRS/GMRS/MURS and potential use for Unmanned Aerial Systems (UAS) detection (around airports in this case).
Was fun putting GMRS radios into people's hands and having the system track their transmissions around an area. These were Motorola XPR6550 and XPR7550e handhelds.
Attached is what a typical node looks like. We had three set up so the system could triangulate position.
I then sent a "curveball" by transmitting from Motorola DTR410 Frequency Hopping Spread Spectrum (FHSS) radios. I could sense them, get a rough bearing and distance, but could not "lock" onto them due to the frequency hopping aspect (902-928 MHz Industrial, Scientific, and Medical [ISM] band).
Anyone else use this system or something else for finding location of radio transmissions (APRS is common and also useful)?
