INPOP is the ephemerides series from the Paris Observatory, more precisely from the IMCCE laboratory. The Paris Observatory has been a central place for astronomy for the last few centuries and the data produces today by the IMCCE is among the most accurate and precise we can produce today.IMCCE

It is now possible to load Binary SPICE files (.bsp) produced by the IMCCE for their INPOP model.

instant = Astronoby::Instant.from_time(Time.utc(2025, 4, 18, 12))


# With NASA/JPL DE

Astronoby::Ephem.download(name: "de440s.bsp", target: "tmp/de440s.bsp")
ephem = Astronoby::Ephem.load("tmp/de440s.bsp")
Astronoby::Saturn.new(ephem: ephem, instant: instant).astrometric.equatorial.declination.str(:dms)
# => "-3° 19′ 48.1206″"


# With IMCCE INPOP

Astronoby::Ephem.download(name: "inpop19a.bsp", target: "tmp/inpop19a.bsp")
ephem = Astronoby::Ephem.load("tmp/inpop19a.bsp")
Astronoby::Saturn.new(ephem: ephem, instant: instant).astrometric.equatorial.declination.str(:dms)
# => "-3° 19′ 48.1212″"
