Solar Panel
Solar Panel is the device that convert solar energy to electricity using photovoltaric cells. Solar panel supplies the power to the battery and components on satellites.
View Factor: Definition and Derivation
View factor is used in calculation of energy transfered by radiation. This article explains the definition and derivation of view factor. Definition of View Factor Suppose there are plane \(i\) and plane \(j\) in vacuum space. The area of plane \(i\) and plane \(j\) are \(A_i\) and \(A_j\). Here, the energy tranfered from plane \(i\)
Thermal Control Subsystem
Thermal Control Subsystem (TCS) manages temperature of satellites. Each component on satellites has its operational temperature range. TCS conducts thermal analysis and design, and determines thermal control components.
Thermal Louver
A thermal louver is the thermal control equipment used for satellites. Thermal louver can change the emissivity of the surface by using blinds.
Feeder Link
ITU Radio Regulations define feeder link as follows: A radio link from an earth station at a given location to a space station, or vice versa, conveying information for a space radiocommunication service other than for the fixed-satellite service. The given location may be at a specified fixed point, or at any fixed point within
Communication Subsystem
Communication Subsystem handles communication in satellite bus systems. Communcation Subsystem:
