The RangePRO Model GSLR-2K-R is a compact OEM laser rangefinder module providing an advanced digital rangefinding capability for military, paramilitary and commercial applications. All assemblies are integrated onto a precision bore-sighted platform.

It integrates with host systems such as weapon, sensing, or surveillance and tracking stations, and thermal imaging cameras. It requires power and control command input, and provides range-to-target and selfdiagnostic data output.

The GSLR-2K-R ranges at low repetition rates over distances to 10km depending on target size, target reflectivity, atmospheric conditions and customer supplied external optics (typically greater than 4.5km for vehicle type targets).

The transmitter is a collimated eye-safe laser system. It can provide ranging rates from single shot up to 1Hz continuously, providing sufficient heat transfer from the unit to the mounting surface is provided.

The unit is fully environmentally sealed and purged and utilises select materials and specialised surface treatments to prevent corrosion. This includes a RoHS compliant Ni-PTFE plated aluminium connector rated at 500h of salt mist.

Advanced digital signal processing techniques are employed to provide accurate, reliable ranging. Signals from the detector are digitally sampled. The samples are examined to determine all potential real target returns. If a valid target is detected within the user-set range gate it's range data is output, if more than one target is detected within the range gate the nearest or farthest may be selected for data output.

All signal and range computation is done "on the fly". Using this philosophy, the only task remaining after the sampling has expired is to transfer the range data through the serial port. Effectively the speed of the signal processing is limited only by the data output rate.

The system employs an adaptive range threshold to compensate for changing noise levels. The worst case for noise is when the system electronics are being operated at the high end of their temperature specification and when ranging is being performed in strong sunlight. The best case is the reverse situation. The adaptive range threshold feature results in more reliable ranging (fewer false alarms) when noise is elevated and higher sensitivity (further ranging) when noise is reduced, thus maximising the system capability under varying conditions. The threshold is calculated on a "shot-by-shot" basis.

RangePRO laser rangefinder software is easily upgradeable, upgrades can be downloaded in the field via a PC.
