Product Description

PC Upper Computer
The LDR20K1 Laser Target Designator is capable of measuring the distance to a target and providing laser target designation for the firing of the target. It is primarily used in airborne applications that require high reliability. It features compact size, lightweight, long-range target designation, high precision, and strong environmental adaptability. The laser target designator can achieve the following control functions through a serial interface: 1) Respond to laser ranging commands and can stop ranging at any time upon receiving a stop command; 2) Output distance data and status information for each pulse during ranging; 3) Ranging has a distance gating function; 4) If no stop command is received after initiating continuous ranging, it will automatically stop ranging after 5 minutes (1Hz) or 1 minute (5Hz); 5) Can set irradiation mode and coding; 6) Respond to laser target designation commands, designate targets according to the set mode and coding, and can stop target designation at any time upon receiving a stop command; 7) If no stop command is received after initiating target designation, it will automatically stop after one cycle of target designation; 8) Output distance value and status information for each pulse during laser target designation; 9) Perform power-on self-test and periodic self-test, and output status information; 10) Respond to start self-test commands and output status information; 11) Can report the cumulative number of laser pulse counts.
