Abstract

Lasers provide a means for transmitting larger quantities of data at higher rates than conventional radio frequency devices and can be utilized during radio silent operations on the battle field. A forward scout needs to be able to observe the positions of various targets and relay that information back to a tactical operations command center in a covert manner. The BiCom device built by Trex Communications provides laser ranging, azimuth and elevation angle to a target, GPS position information, data storage and transmit capability, and full duplex audio transmission capability, all in a 3 kg hand held package. The communication channel utilizes an eye safe lasercom transceiver for covert voice or data transfer at 100 kbps at distances of up to 5 km. The information gathered electronically by the unit is sufficient to calculate the actual GPS positions or military grid coordinates of the observed targets. Several dozen targets can be stored in memory for later transmission via lasercom. Field tests were conducted by US Army personnel to evaluate these units and compare the results with conventional means of target position determination and data transfer. A description of the system and results of these tests are presented.
