Astrodynamics32 is a DM32 statefile for circular-orbit calculations. It takes one known orbital parameter (height, velocity, period, sidereal days, or circumference) and computes the remaining values using stored Solar System constants. Designed for quick, self-contained orbital mechanics work directly on the calculator.

This program suite provides comprehensive mine clearance operations planning for Mine Countermeasures (MCM) assets. The calculator determines the number of passes required to achieve a specified confidence level that mine density has been reduced to an acceptable threshold.

Comprehensive date calculation capabilities for the SwissMicros DM32 calculator, replicating and extending the date functions found on the classic HP-12C financial calculator. The programs enable date arithmetic, day-of-week determination, and liturgical calendar calculations.

📊 Calculate mine clearance passes efficiently using the DM32 calculator, ensuring precision in mine density reduction for effective operations.
