ARB-3D Altimeter

The ARB-3D altimeter is a real-time integrating accelerometer and barometer for computing the absolute values utilizing floating-point mathmatic calculations.  The heart of this altimeter uses the BasicX-24 stamp.

The Accelo-Graph software configures the settings on the ARB-3D and downloads the flight data files.  Testing the continuty and pyro channels can be tested as well as polling real-time acceleration and barometric pressure values. 

The downloaded flight data can be examined as acceleration, thrust, velocity, and altitude over time.  Zoom in on the acceleration and thrust curves for a closer examination.  The thrust curve can be exported as an .ENG file to be opened in wRasp simulation program!  The Accelo-Graph record files (.rcd) is comma delimited so it could be opened in a spread sheet program without any exporting.
