Telemetry is a process that involves the collection and transmission of critical data from a satellite to a ground station. This real-time flow of information serves as a lifeline, providing crucial insights into the satellite’s health, status, and operational parameters.

Through telemetry, satellites continuously send back valuable data on their various systems, including power levels, temperature, onboard instruments, communication links, and overall performance. This data is essential for monitoring the satellite’s condition, ensuring it is functioning optimally, and promptly identifying any anomalies or issues that may arise during its mission.

The telemetry data is transmitted through radio frequency signals from the satellite’s onboard sensors and systems. These signals travel across vast distances through space, reaching the ground station, where they are received and processed by sophisticated systems. Skilled engineers and operators at the ground station then analyze the telemetry data, interpreting the satellite’s performance, and making informed decisions regarding its operation.
