Tian Jun Aerospace Company provides a powerful brain for satellites by adopting integrated design architecture. The sub-system components of the satellite are gradually transformed into multifunctional structural components through the superposition of satellite motherboards, and together with power supply and payload, the whole satellite is formed. This depends on the systematic combing and integration of satellite power flow, heat flow, information flow and energy flow through electronic network information technology, thus reducing the number of equipment and reducing the cost.
