Paul Collier of Perth Advanced Rocket Club Western Australia has submitted his implementation of MRDR-2 which is a 2 station Alt/Az data reduction program, originally written by G. Harry Stine. The code can be found in the back of the Handbook Of Model Rocketry.

This implementation was written in visual basic 6 and the source is included in the zip file, along with a pre-compiled exe.

This version also allows users to save the results to a file for multiple flights - it also stores the name of the rocket and the name of the owner and the date and allows this info to be printed, which makes is good for club launches.

It's not very pretty, but it does what it's supposed to do.

It's freeware!

Just download MRDR-2.ZIP (128K).
