By now, the system has been integrated, and [[ Various Tests performed on Integrated Satellite |several tests]] have been performed on it. If required, certain changes are made after the tests, and now the system is ready to be launched. This phase starts with the launch and covers the mission life of the satellite. The satellite has to perform all the functions for which it has been designed. To achieve this, one requires regular communication with the satellite so that one can uplink the data as well as receive the downlink.

==Health Monitoring and Analysis of Components==

Satellites are complex systems and need to be closely monitored by frequently tracking and receiving data of several onboard parameters. This helps in detecting any anomalies or possible failures in the system. The health monitoring data is downlinked from the satellite and received on the ground station. It is called telemetry. Using this data, one gets to know if the satellite is functioning properly or not. The diagnosis of failure of a component is done through this data. Thus, we can investigate such faults and properly document them for future references.
