Coordinate Converter for Astronomy
AstroCC is written in Java and ...
- Runs on Windows, Mac, and Linux
- Accesses SIMBAD
- Provides ephemerides for the Moon and major planets
- Provides Julian and barycentric dates and times
- Has been extensively validated
AstroCC is a coordinate conversion utility for astronomy. It accepts an object
designation or the coordinates of an object and calculates coordinates in alternative
systems, and at different dates, times, and locations. It also provides lunar and bright
planet coordinates to aid in planning observations.
The changes in this latest release include
- More robust SIMBAD communication
- Implementation of contributions from Cheolha Lee of Ball Aerospace that
- Correct sky calculation algorithm bugs
- Improve precision in lunar and solar positions
