Допплеровский датчик ск-ти для ЛА постоянной геометрии (а мож под fixed-wing имеются в виде все самолёты), меряет 3 проеции ск-ти: по курсу, снос и вертикальную.
Description
The AN/APN-218 Doppler Velocity Sensor (DVS) is a reliable, high-performance, nuclear-hardened Doppler radar for fixed-wing aircraft. Usually referred to as the Common Strategic Doppler (CSD), it is combined with a GroundSpeed Drift Indicator (GSDI) to process digital velocity data from the radar and display the groundspeed and drift angle. The DVS is an LRU consisting of 10 Shop Replaceable Units (SRUs). The GSDI is also an LRU and consists of three SRUs. The AN/APN-218 continuously measures three velocities: heading (Vh), drift (Vd) and vertical (Vz). These provide accurate in-flight data to navigation equipment. It can output data for all three co-ordinates from the microcontroller and process it into either MIL-STD-1553A or ARINC 575 formats.
