Optical Crosswind Ballistic Measurement

VENOM stands for Velocity Extracted from scintillation via Optical Measurement. A weapon-mounted wind measurement device contains all the functions of laser rangefinder, ballistic computer and other sensors, including inclinometer, thermometer, barometer, etc. VENOM connects to external devices such as Kestrel or PDAs. Range capability is 1800-2000m with accuracy of measurement better than +-0.5mph.

VENOM takes all gun data into embedded ballistics computer, including:

  • Sight Height
  • Bullet Diameter and Weight
  • Zero Range
  • Ballistic Coefficients
  • Rifle Twist Rate
  • Muzzle Velocity

Target Engagement

  1. Once in position, power VENOM ON
    – System is in standby, waiting to engage
    – Gun/ballistic parameters can be verified if desired
  2. When ready to engage, press either the pressure switch on the butt-stock or the ENGAGE button on the system
  3. Target is lased and range and full value crosswind is computed – environmental sensor data is acquired from internal sensors or external sensors (Kestrel)
  4. Elevation and windage holds are displayed and can be seen without having to break the cheek weld
  5. Operator holds or dials to specified elevation and windage and engages the target
