Field modules

Two tools, built for the same conditions

Each module installs to the home screen and runs with the radio off. Nothing you enter leaves the device: there is no account, no upload and no analytics. Open one, and it stays available whether or not you have a signal.

Recon Module

Reads the position out of a photograph and prints the military grid onto the image itself, so the picture and its coordinate cannot be separated.

EXIF parsed in the browser — the photograph is never uploaded
MGRS to one metre, verified against 2,400 reference conversions
Stamped image downloads straight to the device

Battle Procedure

Carries the sixteen steps of battle procedure, the radio reports that go with them, and the calculations the estimate needs — bilingual, and legible at night.

Sixteen steps with a 1/3 – 2/3 timeline that tracks where you are
Orders builder that compiles to a spoken set of orders
Nine-liner, call for fire, SITREP and LOCSTAT with prowords
Red-light display for use in darkness

Open Sunray Sequence

Used together

Gridnorth reads a grid off a photograph. Sunray needs that grid on line 1 of a nine-liner and line 2 of a call for fire. Send it straight across rather than copying it by hand — transcribing a grid under pressure is how the wrong one gets transmitted.
