Full 10-digit MGRS for all users. Offline maps, Meshtastic mesh networking, topographic tiles. DAGR-class navigation — zero network required.
The military's DAGR (AN/PSN-13) costs $2,500 and weighs a pound. Red Grid MGRS puts the same core land navigation capabilities in your pocket — live 10-digit MGRS, magnetic declination, waypoints, bearing and distance — for free. No network required. No data collected. No accounts to create.
YOUR PHONE. DAGR CAPABILITY.
Like the Defense Advanced GPS Receiver carried by warfighters worldwide, Red Grid displays your Military Grid Reference System position in real time with 1-meter precision. But Red Grid goes further — adding offline tactical maps, Meshtastic mesh networking, NATO voice readout, tactical report generation, and pace counting that the DAGR doesn't offer.
