Battle field 2 drone station1/9/2023 ![]() ![]() Other specialized payloads, such as SIGINT packages, or new lightweight synthetic aperture radar (SAR)sensors with all-weather imaging capability, are now being fielded as well. The turret may also include a laser designator to allow the UAV to mark targets for smart weapons. The UAV sensors are generally housed in a turret underneath the aircraft, and almost always feature day-night imagers. For this reason, "endurance" is a more useful specification than "range". This is usually the determining factor in "range" specifications for such UAVs. The need to stay within radio range restricts combat surveillance UAVs to ranges within a line-of-sight of the transmitter. However, combat surveillance UAVs usually use the autopilot to get to the operating area, with the aircraft then operating by radio control to find targets of opportunity. Navigation is often verified by a GPS-INS navigation system. The flight-plan is set up by displaying a map on a workstation, clicking on the desired map coordinates with a mouse or directly on to a touch-screen, and then uploading the flight-plan into the UAV. The autopilot directs the aircraft from sets of waypoints programmed in before takeoff. They are directed by an autopilot system with RC backup. They are generally powered by small rotary or two-stroke piston "chain saw" engines. The function of a combat surveillance UAV is to observe events on a battlefield in real-time, orbiting over the battle area and relaying intelligence to a ground control station. These battlefield UAVs fall into two broad categories, which can be designated for convenience as "combat surveillance" and "tactical reconnaissance" UAVs. During the 1980s, all the major military powers and many of the minor ones acquired a battlefield UAV capability, and continue to expand that capability. With the successes in southern Lebanon, international interest in battlefield UAVs picked up significantly. ![]() Very few of the technologies they used were all that new, but the Israelis finally achieved the proper formula for operational success, using their battlefield UAVs to help destroy Syrian surface-to-air missile sites and assist in other combat operations. Israelis pioneered the operational use of battlefield UAVs in the early 1980s, during their operations in southern Lebanon. UAVs, such as the Northrop Falconer, had been developed for battlefield reconnaissance beginning in the 1950s, but these machines saw little or no combat service. ![]()
