特点
- Astronomical position calculation (planets,stars,Moon,Sun,satellites),ephemeris loading (JPL DE series,TLEs for satellites),coordinate transformations (alt/az,RA/Dec,galactic),timescale conversions (UTC,UT1,TT,TAI),precession,nutation,aberration,topocentric and geocentric positions,event finding (rise,set,transit,conjunctions)
定价
- 免费
- Accurate and modern astronomical calculations, well-documented with clear examples, easy to use API, handles time zones and complex astronomical phenomena correctly, actively maintained.
- Primarily focused on positional astronomy (not astrophysics like spectra or stellar evolution), requires downloading ephemeris files for high accuracy, understanding of astronomical coordinate systems and time is beneficial.
最适合：
- Astronomers, astrophysicists, satellite trackers, and hobbyists needing to compute precise positions of celestial objects and satellites.
