List three subsystems of a SARSAT satellite and tell what the function of eCh subsystem is.

Please help I can't seem to find them.

To find the three subsystems of a SARSAT satellite and the function of the eCh subsystem, you can follow these steps:

1. Start by searching for reliable sources that provide information about SARSAT (Search and Rescue Satellite-Aided Tracking) satellites. Government websites, academic papers, and space agency resources are good places to start.

2. Look for documents or articles related to the design and components of SARSAT satellites. These sources should provide information about the various subsystems used in these satellites.

3. Once you identify the subsystems, search for details about each subsystem to understand its purpose and function. Government documents or technical specifications related to SARSAT satellites will likely include this information.

Now, to save you some time, I can provide you with the three commonly known subsystems of a SARSAT satellite and the function of the eCh subsystem:

1. Communication Subsystem: This subsystem consists of antennas, transmitters, receivers, and related components. Its function is to receive distress signals from emergency beacons on Earth and transmit them to the Ground Stations.

2. Payload Subsystem: The payload subsystem contains the Search and Rescue Repeater (SARR), which captures and retransmits distress signals. It also includes other components necessary for signal processing and data handling.

3. Power Subsystem: This subsystem manages the power system on the satellite, including solar panels, batteries, and power distribution components. Its function is to generate and regulate power to ensure the satellite's proper functioning throughout its mission.

Regarding the eCh subsystem, I couldn't find any specific information on it. It's possible that the term "eCh subsystem" may be a typo or a less common designation. If you have any additional information or clarification on the eCh subsystem, I can try to assist further.
