Marsa Systems 33L HD Altimeter
The Marsa 33L HD--
Marsa Altimeter Comprehensive List of Features
Marsa Altimeter Comprehensive List of Features
- Complete programmability without the need of a computer
- Four current limited and protected outputs
- Output current is measured during firing and controlled to 6A max
- Fully LiPo battery safe without regards to battery size (2S LiPo recommended)
- Apogee detection options
- Barometric only
- Accelerometer only
- Barometric OR Accelerometer which ever occurs first
- Kalman filter fusion of Barometric and Accelerometer inputs
- Adjustable delay in 0.1 second increments
- Main Altitude events
- Deployment altitude adjustable in 100ft increments
- Timer events
- Delay from Launch Detect
- Delay from Motor Burnout
- Altitude - time lockout for staging protection
- On-board Diagnostics
- Live barometric and sensor accelerometer readings
- Battery voltage
- Actual e-match resistance readings (diagnostics and for continuity check)
- Output FET test and test-LED's for each output channel
- Flight simulator to test and dry-run altimeter event programming
- Power on Self Test (POST) and Continuity testing
- All sensors tested for normal outputs
- Ematch resistance checked, POST will fail if resistance is too or too low (short circuit)
- POST will fail if battery voltage drops below 6.5V
- Output channel and channel programming checked for consistency.
- Post will FAIL if there is an ematch attached to channel with no events programmed
- Post will FAIL if there is no ematch connected to a programmed channel
- Audio and visual indicators
- Beeper with programmable frequency tone
- Connection for external LED
- On-board super bright Cree LED on Marsa33LHD
- Reliability and Robustness
- All flight critical components surface mounted
- 5V signal levels for greater RF interference and noise immunity
- Data
- Flight data storage for last 2 flights
- Motor thrust and impulse characterization analyzer within MarsaConnect (PC Windows only)
- Expandability
- Extend to 9 programmable with MarsaNet and remote Pyro Modules (MrfPyro)
- Future MarsaNet and other expandable modules in development
Are you planning to fly high? Like out of the atmosphere? Consider adding the option Conformal Coating option.
The conformal coating will also provides additional chemical, shock and environmental protection.
The altimeter is oven dried, coated with a Milspec urethane coating and cured.
This coating adds $20 to the price of the altimeter and in our opinion is well worth the small extra cost..
