About:
Calceph is a C library designed for accessing and reading binary planetary ephemeris files such as INPOP, JPL DE, and PK. It provides a robust API for retrieving high-precision position and velocity data for celestial bodies. This tool is essential for astronomers and physicists requiring accurate ephemeris calculations for research and simulations.
Key Features:
  • Support for multiple ephemeris formats (INPOP, JPL DE, PK)
  • High-precision position and velocity retrieval
  • Thread-safe C library API
  • Command-line interface for quick queries
Use Cases:
  • Calculating precise planetary positions for astronomical research
  • Simulating solar system dynamics in physics applications
  • Validating ephemeris data accuracy in aerospace engineering
Alternatives:
  • SPICE – NASA's SPICE toolkit is more comprehensive but significantly larger and complex to integrate for simple ephemeris access.
