STLASS Surface Target Laser Aim Scoring System |
The STLASS system provides high fidelity reconstruction of laser designated weapons training engagements. The system consists of three major elements:
A weapon platform subsystem with Digital Data Recording Unit (DDRU) which interfaces with the weapon and avionics data buses. The DDRU records weapon platform data on removable media for transfer to the debrief subsystem at completion of the training exercise.
A target platform subsystem that observes laser energy incident on target for the purpose of identifying laser PRI, as well as spot location and extent. The data is then transferred via Iridium satellite to a remote server for later use by the debrief subsystem.
A debrief subsystem that combines data from the weapon and target platforms to reconstruct a high fidelity 3D graphical depiction of the engagements. This permits assessment of target acquisition and pre launch procedures, event time line, and laser tracking performance during engagements.
The Surface Target Laser Aim Scoring System (STLASS) was developed to meet a critical need for high fidelity non-destructive training with laser designated weapons against moving targets at sea. The system operates transparently to the crew during training exercises, does not require any mission specific setup, and places no restrictions on training engagement geometries or location. The initial deployment of the system was with H-60B/H helicopters fitted with the Hellfire weapon system. The training target was the High Speed Maneuvering Sea Target (HSMST).
The system is extremely flexible and can be configured for use with any weapon platform that has a 1553, or equivalent, weapon and avionics data bus. The system is also suitable for mounting on a wide range of land or sea based targets with minimal interface modifications. The system operates with any laser designator having a wavelength of 1000 to 1600 nanometers and a PRI range of 50.1 to 112.7 milliseconds.
