Satellite tracking library for C++
This library aims to solve typical use-cases for satellite and other celestial objects tracking for radio HAM. Additionally, it strives to have fully documented algorithms implementations, with exact references to formulas from whitepapers and books.
The library only provides core functionality, and some glue logic still needs to be implemented in the application. For example, the application which uses this library needs to take care of leap second and Earth orientation tables.
The Astro Core library is licensed under the terms of the MIT license. See LICENSE for more information.
-
IERS, which provides Earth orientation tables, including description of the provided data tables: https://www.iers.org/
Note: The Astro Core library mainly uses information table structure provided by IERS. There are various tables in the
datafolder, but they are only used for regression tests. For the proper operation in the user application it is to provide up-to-date IERS tables. -
SatNOGS, which provides machine-readable information about satellites and their transmitters: https://satnogs.org/
Note: The Astro Core project only provides functionality to parse data provided by SatNOGS. The library itself contains no information about satellites.
-
CelesTrak, and David Vallado's SGP4 model library: https://celestrak.org/publications/AIAA/2006-6753/
The satellite prediction functionality in Astro Core is implemented using Vallado's SGP4 library.
