Datasets Commands
Download and query satellite ephemeris data and ground station information.
Overview
The datasets command group provides access to: - CelesTrak - Satellite TLE (Two-Line Element) data - Ground Stations - Commercial ground station network databases
CelesTrak Commands
celestrak download
Download satellite ephemeris data from CelesTrak and save to file.
