ANV-353
Doppler Velocity Sensor
The ANV-353 is a fully digital DVS that provides a continuous and accurate three axes velocity measurement for both fixed- and rotary-wing aircraft applications.
It is a single-unit, low-power sensor, specifically designed for integrated systems. The applications of DVS ANV-353 are the following:
- Source of velocity vector data for Doppler/Heading Navigation
- Source of velocity vector for approach down to hover and hover for Autopilot
- Source of velocity vector for ASW sonobuoy control
- Source of velocity vector data for weapons aiming during NOE attack for anti-tank helicopter
- Source of velocity vector data for INS/Doppler hybrid navigation
- Source of velocity vector data for INS in-flight alignment using Doppler
