... This would improve the reliability of each individual satellite by mininiizing out-of-serv~ce time, thus improving the percentage of time that a full 24-satellite constellation would be available to users. Block ~ R satellite communication crosslinks should be used to the extent possible with the existing crosslink data rate to support on-board satellite health monitoring for improved reliability and availability and in order to permit a more rapid response time by the operational control segment.
