- 6.6.9.2 COLLISION AVOIDANCE
| 6.6.9 MISSION INTEGRATION ANALYSES SpaceX will conduct the following analyses in support of the Payload if required. All other environments are verified by Customer using requirements found in Section 3. 6.6.9.1 TRAJECTORY SpaceX performs a trajectory and performance analysis in order to analyze the following Mission parameters a. The nominal flight timeline, profile (plots of altitude and acceleration. vs. time, and ground track b. The free molecular heating environment at fairing jettison c. The Earth-Centered-Earth-Fixed (ECEF) Payload separation state vector d. Payload and Co-Payload(s) deploy timeline e. Orbit injection accuracy SpaceX analyzes and implements a single Earth-referenced Launch trajectory, a single Earth-referenced ascent attitude profile, and a single Earth-referenced Payload separation attitude, which will be used for all dates and times throughout the Launch Period. SpaceX does not implement multiple trajectories for various dates/times within the Launch Period, RIDESHARE PAYLOAD USER’S GUIDE © Space Exploration Technologies Corp. All rights reserved. No US. Export Controlled Data. 46 and does not provide sun-referenced or inertially-referenced attitudes during ascent or for Payload separation. Results will be provided by SpaceX. 6.6.9.2 COLLISION AVOIDANCE SpaceX performs an analysis to determine the need fora collision avoidance maneuver following separation of Payload and Co-Payload(s). This analysis will characterize the relative separation distance between the second stage and the Payload for one orbit after separation. This analysis will assume that no propulsive activities are executed by the Payload during the period analyzed. SpaceX does not perform additional analyses with respect to collision avoidance of potential debris or other space objects. These results will be provided by SpaceX as part of the trajectory and performance results described in Section 6.6.9.1. SpaceX coordinates with applicable US regulatory authorities, such as the FAA and the Combined Space Operations Center (CSpOC), to select a Launch Window that results in a sufficiently low risk of collision with another space object during the Mission. In order to facilitate this coordination with the regulatory authorities, SpaceX will utilize the separation velocity imposed on the Payload by the separation system as documented in the Payload ICD and position predicted by the Trajectory analysis. Any Payload propulsive maneuvers or secondary Payload deployments within three (3) hours of Launch must be coordinated with SpaceX for inclusion in CSpOC analysis and will be documented in the Payload ICD.
