An optical targeting application designed to enable users to accurately calculate a target position without the need to have visibility of the target or knowledge of their own position. OPTOnav creates and uses a database of geotagged imagery held on a user device or remote server.

CAT 1 Level Target Coordinates

Point-to-Point Survey Measurements

Operates in GNSS denied areas

ITAR-Free Software Package


OPTONAV identifies the same point/target in one or more images computing 3D position solutions in WGS84, UTM, MGRS and outputting in 9-line format. Position is calculated with a confidence figure where users can expect to achieve a CAT 1 level target coordinates.


OPTONAV is an ITAR-free package allowing users to confidently compute target positions from a range of different sensors, including UAV’s sighting systems, Laser Range Finders, professional cameras and mobile devices.


Targeting can be achieved quickly and augmented in-field with real time imagery. The ability to mensurate  target and compute own position in GNSS denied environments is a core capability.
