Steps

  1. Register an N2YO account, open your profile page, and generate a REST API key (license key).
  2. Look up the target satellite's NORAD catalog ID beforehand, since the pass-prediction endpoints require it as a path parameter.
  3. Send a GET request to https://api.n2yo.com/rest/v1/satellite/radiopasses/{NORAD_ID}/{lat}/{lng}/{alt}/{days}/{min_elevation}/&apiKey=YOUR_KEY to get radio-relevant pass predictions, which do not require the satellite to be optically visible (unlike the separate visualpasses endpoint).
  4. Parse the JSON response's 'passes' array for start/end azimuth, elevation, and UTC timestamps for each predicted pass.
  5. Track your call volume against the documented limit of roughly 1,000 transactions per hour to avoid having your API key suspended.
