Ancillary Data
Ancillary data refers to any additional information that is transmitted along with the primary data in a spacecraft communication system. This data can include information about the spacecraft's health and status, as well as environmental data such as temperature and radiation levels. Ancillary data is critical for ensuring the safe and efficient operation of spacecraft, as it allows ground controllers to monitor the health of the spacecraft and make necessary adjustments to its systems. Additionally, ancillary data can be used to enhance the scientific value of data collected by spacecraft instruments, by providing context and additional information about the environment in which the data was collected.
