| Description |
PDF document and suite of MATLAB functions that compute low-precision ephemerides of the sun, moon, and planets. The MATLAB functions that compute an ephemeris for the Sun, Moon and all planets except Pluto are based on the algorithms described in Low-Precision Formulae for Planetary Positions, T. C. Van Flandern and K. F. Pulkkinen, The Astrophysical Journal Supplement Series, 41:391-411, November 1979. To the precision of implemented algorithm (one arc minute), these coordinates can be considered to be true-of-date. |
