TLE Provider

Pulls TLE data from multiple sources and exposes the result through a REST API.

The OpenAPI specification is available here.

The following data sources are available :

• Celestrak: Query data directly from the Celestrak JSON API URLs
• File: Expose the data pulled from the text file dump generated from Celestrak (example available in the samples folder).

Usage

tle-provider serve --config <configuration file>

sample configuration file:

server_port: 5000
data_source: "celestrak"
celestrak_configuration:
  all_satellites_url: "https://celestrak.com/NORAD/elements/gp.php?GROUP=active&FORMAT=json"
  geo_satellites_url: "https://celestrak.com/NORAD/elements/gp.php?GROUP=geo&FORMAT=json"
  celestrak_refresh_rate_hours: 12
file_source_configuration:
  source_file_path: "./samples/active_satellites_tle.txt"
  refresh_rate_seconds: 30

• server_port: exposed port for the service.
• data_source: either celestrak or file.
• celestrak_configuration:
  • all_satellites_url: the URL to use when querying the Celestrak website for all satellites.
  • geo_satellites_url the URL to use when querying the Celestrak website for geosynchrnous satellites only.
  • celestrak_refresh_rate_hours: period at which to query the data from Celestrak.
• file_source_configuration:
  • source_file_path: path to the TLE source file.
  • refresh_rate_seconds: revisit rate of the source file.

Note: when performing Run(), the server starts a separate thread for pulling data from the source only if the refresh rate is set at more than 1 second.
