Special Data Request Form

Data is available for all unclassified objects from 1957 through the latest GP data update. Please ensure that the data you are requesting is not already available in the online Historical Archives prior to submitting a Special Data Request.

All fields must be filled out for your request to be fulfilled. Requested data will be sent to the e-mail address provided. A copy of the request will also be automatically sent to the requestor's e-mail address as confirmation of receipt. If you do not receive this e-mail confirmation, you may have entered your address incorrectly or the message may have gone into your spam folder or been blocked by your e-mail system.

Data will be sent as individual text attachment(s) (e.g., .txt, .xml, .json, or .csv) to an e-mail message to the e-mail address provided within 2 hours of your request.

If you are unsure of the NORAD Catalog Numbers for the objects you need element sets for, please check the online Satellite Catalog to search for the correct NORAD Catalog Numbers.

This new form now supports sending data in the new GP formats, in addition to the legacy TLE format. It also supports 9-digit NORAD Catalog Numbers. Data in TLE/3LE/2LE formats is only available for 5-digit catalog numbers.
