Theon Ares LRF Long-Range Laser Rangefinder with Designator and Digital Compass for Forward Observers

The Theon Ares LRF is the laser rangefinder designed for the forward observer (FO) and fire support team who needs to transmit observation data with the precision and standard format that the artillery command system requires to calculate the firing solution without manual FO corrections — a process that in analog methods consumes 3-5 minutes of radio exchange and that with the Ares LRF reduces to 30 seconds of automatic STANAG 4355 data export to the C2 system.

The Class 1 (eye-safe for the FO) laser rangefinder operates at 1550 nm with 500 μJ pulse energy, reaching 6 km on high-reflectivity targets (metallic vehicle, concrete building) and 4 km on non-cooperative low-IR-signature targets (individuals or equipment with anti-IR treatment), with ±1 meter accuracy at any distance within the operational range, sufficient for 155mm cannon artillery fire adjustment precision.

The ferrofluid digital compass accurate to ±1 milliradian (equivalent to ±0.057°) provides the observation azimuth with the precision artillery howitzer fire calculation requires — a 1 milliradian error in the FO's azimuth at 5 km target distance produces a 5-meter deflection error at the projectile's impact point, within the lethal radius of 155mm fragmentary explosive ammunition — without field calibration or proximity-to-metals compensation via the integrated ambient magnetic field compensation algorithm.

Observation data export in STANAG 4355 format (AFATDS Message Format) via RS-232 / USB / Bluetooth data interface includes: target UTM/MGRS calculated, azimuth, distance, estimated altitude (triangulated with inclinometer), target category, and GPS-synchronized timestamp, ready for direct import into ATAK (AFATDS plugin), LLDR, or any NATO-compatible artillery command system without manual retranscription.
