6.5.6 PAYLOAD LICENSING AND REGISTRATION Customer will flow down its responsibilities relating to Payload licensing and registration under the Agreement (including registration pursuant to the Convention on Registration of Objects Launched into Outer Space) to each of its customers, in writing. Evidence of proper flow-down will be provided to SpaceX upon request. Customer will provide a letter in the form of Appendix F, certifying that Customer has obtained all required Licenses and that all Payload information provided to SpaceX and/or any licensing agencies is complete and accurate. 6.5.7 COORDINATION WITH SPACE SITUATIONAL AWARENESS AGENCIES Customer is responsible for registering all deployed objects with the 18 th SPCS to assist with the tracking and identification of all deployed Payload Constituents. More information can be found at https://www.space-track.org on how to register a Payload and the process for communicating and coordinating with the 18 th SPCS. If required, SpaceX can provide direct contact information with personnel from the 18 th SPCS. To further aid in US. Space Force satellite tracking, identification, cataloging and collision avoidance screening, SpaceX strongly recommends customers publish forward predicted satellite ephemerides and covariance to https://www.space-track.org as quickly as possible post Launch. If Customer is unable to generate propagated ephemeris and covariance SpaceX strongly recommends they work with a commercial provider (SpaceX can provide recommendations) to contract for this work. Publishing predicted ephemerides and covariance drastically improves and accelerates the cataloging process by USSPACECOM, as well as enhancing collision avoidance screening. Furthermore, SpaceX recommends Customers consider adopting and following the best practices outlined in the NASA Spacecraft Conjunction Assessment and Collision Avoidance Best Practices Handbook, which can be found at https://nodis3.gsfc.nasa.gov/OCE_docs/OCE_50.pdf
