The Raven2 Altimeter


The 70G/35G dual-axis, and 250G single-axis versions of the Raven2 are now available.   

 Also check out the new Raven Av-bays for a high-performance av-bay with no wiring!

Image enlarged for clarity.   Actual size only 1.80" x 0.8" x 0.55."  Raven2 has identical dimensions.


Only 1.80" long x 0.8" wide x 0.55" thick!


Features include:

Lots of high-quality recorded data:

4 high-current
programmable outputs:
  • 9-Amp outputs compatible with all batteries from a single Li-Poly cell to a 20V pack. (altimeter power input up to 10V)
  • Default output settings:
    • Mach-immune, accelerometer-based apogee deployment
    • Main deployment at 700 feet
    • Baro-based backup apogee deployment
    • Backup deployment 1.5 seconds after main deployment
  • Additional user-selectable output logic options can be selected in combination for each output:
    • Accel > user value 1 (ignition detection)
    • Accel < user value (burnout detection)
    • Filtered pressure increasing (baro apogee detection)
    • Filtered pressure decreasing (for staging)
    • Time > user value (simple timer)

 
    • Time < user value (vertical staging check)
    • Altitude < user value 1 (low altitude deploy)
    • Altitude > user value 2  (vertical staging check)
    • Altitude < user value 3 (landing detection) (New!)
    • Velocity < 0 mph (apogee detection)
    • Velocity < user value 1 (Mach inhibit)
    • Velocity > user value 2 (staging input)
    • Time delay after other conditions met (backup)

 
  • 400 Hz axial accelerometer, +/- 70 Gs
  • 200 Hz lateral accelerometer, +/- 35 Gs
  • 250 G single-axis accelerometer available as an option
  • 20 Hz Baro data, +/- 0.3% accuracy!
  • 20 Hz voltage on each of 4 deployment outputs
  • 40 Hz output current
  • 20 Hz high-precision temperature sensor
  • 20 Hz for All flight events used for deployment logic.
  • Flight counter
  • All output program settings
  • Accelerometer calibrations used during the flight
  • Pad altitude ASL
  • 8 minutes of high-rate data+ 45 minutes for each flight.  The newest 5 flights are stored.  (New higher capacity!)

 

 

  • All of the above flight events are recorded at 20 Hz in the Flight Event Register, great for verification of the altimeter functions in test flights or simulated flights.
  • Screw terminal with 0.1" spacing

 


Simulated test flight:

A sophisticated built in test exercises all sensors and all outputs with a realistic simulated flight.  Verify that your ematches work with your battery, verify your flight program, and view all the recorded data from your "flight" without leaving your computer.


Compatible with the Featherweight Interface Program

Raven has full functionality with either end up!

Visible and audible readout of individual channel continuity and battery voltage.

User-calibration of accelerometer




$165.00 each

Featherweight av-bays and switches also available
