Tactical Engagement Simulation System (TESS) Improved Laser Encoding and Decoding

The Armys Multiple Integrated Laser Engagement Simulation (iMILES) currently uses a 904.5 nm wavelength laser link along with silicon photodiodes at a receiver (target). Several improvements are expected in the laser link capability with a change from 904.5 nm to the 1550 nm wavelength. One dramatic improvement could be range finding during line of sight tactical engagement. Range finding can improve situational awareness in the Armys simulation and training exercises, and eliminate the need for detector threshold to achieve roll-off. Additional improvements include improved atmospheric propagation of the laser pulses, reduced noise from background lighting, increased transmission through battlefield obscurants, increased eye-safety, and increased data rate.
