5 SSA Sharing Agreements Agreements are required by US law The Secretary of Defense may provide space situational awareness services and information to, and may obtain space situational awareness data and information from, non-united States Government entities in accordance with this section. Any such action may be taken only if the Secretary determines that such action is consistent with the national security interests of the United States. Subsection A, Title 10 USC Section 2274 The Secretary may not provide space situational awareness services and information under subsection (a) to a non-united States t Government entity unless that t entity enters into an agreement with the Secretary under which the entity-- (1) agrees to pay an amount that may be charged by the Secretary under subsection (d); (2) agrees not to transfer any data or technical information received under the agreement, including the analysis of data, to any other entity without the express approval of the Secretary; and (3) agrees to any other terms and conditions considered necessary by the Secretary. Subsection C, Title 10 USC Section 2274 UNCLASSIFIED 5

10 Basic CA Sir/Ma'am, The United States Joint Space Operations Center (JSpOC) has identified a predicted conjunction between Satellite A (SCC# 12345) and Satellite B (SCC# 56789). Time of Closest Approach: 25 JUL :33 UTC Overall miss distance: 558 meters Radial (du) miss distance: 126 meters In-Track (dv) miss distance: 87 meters Cross-track (dw) miss distance: 537 meters Primary Object: Satellite A (SCC# 12345) Secondary Object: Satellite B (SCC# 56789) Primary Radial Error (U): 11 meters Secondary Radial Error (U): 45 meters Primary In-track Error (V): 80 meters Secondary In-track Error (V): 1521 meters Primary Cross-track Error (W): 3 meters Secondary Cross-track Error (W): 99 meters Please reply to this message to acknowledge receipt of this close approach notification. It is possible to provide another estimate using owner/operator ephemeris data. If the satellite operator is interested please have them reply to all addresses listed in the Cc line. is the preferred method of communication. Very Respectfully, UNCLASSIFIED 10
