This Raven 2 Altimeter is only 4.5cms (1.8") long and has 4 outputs. It is able to record a large amount of high-quality data and has all the features (and then some) you would expect from the most powerful flight computer on the market and it's less than half the size of others and at a great price. You can fly it right out of the box using the default redundant dual-deployment settings for the outputs, or use the easy-to-use Featherweight Interface Program to set up any staging or airstart events you decide to opt for.
The Raven 2 has full functionality with either end up! Both visible and audible readout of individual channel continuity and battery voltage.
User-calibration of accelerometer is included
4.5cms (1.80") long x 2 cms (0.8") wide x 1.4cms (0.55") deep.
400 Hz axial accelerometer, +/- 70 Gs
200 Hz lateral accelerometer, +/- 35 Gs
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.
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!)
Each Raven 2 has 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 213m (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)
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
