Description

In this course study of Satellite Sub-Systems components such as Attitude and Orbit Control system, Telemetry tracking and command subsystem, Attitude Control subsystem, Power systems, Communication subsystems, Satellite Antenna Equipment. The subsystem components play an important role at ground as well as in satellite stations. In telemetry tracking and command system understand the pulse sending and receiving command generated allotted to the satellite for selection of transponder, power amplifier, power supply and channel selection with or without frequency reuse. In satellite antenna equipment, understand the use of antenna with Circulator for transmission and reception purpose. Antenna use for telemetry tracking command for the satellite. Satellite health observed by the various sensor present on satellite will provide the information for diagnosing and communication purpose.

In Satellite Link design study basic transmission theory. Understand the concept of system noise temperature at front end. Concept of gain to temperature ratio studied in detail. Formation of basic link and its analysis with respect to the interference in the system. Clear concept of the design of satellite links for a specified carrier to noise ratio with and without frequency reuse. In detail explanation of satellite link budget for various applications. Link design for various condition and environmental factors to be consider.

Who this course is for:

  • Engineer able to design the satellite link budget.
  • Engineer understand the required gain and noise for link
