functional testing
Investigations into how well a spacecraft’s subsystems work, individually and integrated, to satisfy mission requirements in a range of operational scenarios. After a subsystemThe busThe bus provides "housekeeping" functions necessary to make the payload work. Includes various subsystems that produce/distribute electrical power, maintain correct temperature, process and store data, communicate with other spacecraft and Earth-bound operators, control the spacecraft's orientation, and hold everything together. More provides “housekeeping” functions necessary to make the payloadAn assembly of spacecraft components that collect, process, store, and transmit payload-mission and bus-housekeeping data. The communication and data-handling subsystem (CDHS) acts as the ears, brain, and mouth of the spacecraft • It has two primary portions — communication and data handling • It translates raw data from the payloads and subsystems into useful information and sends it to the ground system • Commands from ground controllers generally request information from and give specific instructions to individual subsystems More work. Includes various subsystems that produce/distribute electrical powerOrbiting spacecraft periodically pass through Earth’s shadow (enter eclipse). During these eclipse periods, the incident solar energy drops to zero, and the solar cells stop producing power. More, maintain correct temperatureA method to maintain a spacecraft's internal temperature using a closed-loop control system to measure current temperature and adjust inputs, outputs and internal heat flow. It requires a working fluid, heaters, pumps, or other mechanical devices. More, process and store data, communicate with other spacecraft and Earth-bound operators, […]
