【實用工具app】AstronauticCalc|最夯免費app-綠色工廠好玩App

This app is written for space and spacecraft engineers. Taking its cue from a calculator app, it then expands that to add in specific altitude- or radius-based calculations for items of interest.The calculator value in the screen with a single button press is accepted as input as either a radius value or as an altitude value for calculation of the orbit-related values of interest.So, it's a fully featured calculator for mission analysis!- Period- Circular velocity- Escape velocity- Plane change delta V- Revs/day- Max duration for an eclipse in a circular orbit- Apparent angular radius of the Earth- Range to horizon- Nodal precession rate- Sun-synchronous inclination- Maximum time in view above a ground station for various elevation angles- Range for a satellite from a ground station for various elevation angles - Convert between radius and semi-major axis- Convert between kilometers and Nautical milesSuggested additions / omissions / corrections to: sdawson1969@me.comSDD 5/28/2012
