Marsa Altimeter Comprehensive List of Features

• Complete programability 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
