A satellite contains several key components: a power system that uses solar arrays and batteries to provide energy; a transponder that receives and transmits frequencies as the "brain" of the satellite; sensors like OLI and TIRS that collect images and temperature data of the Earth; a solid state recorder that stores the data; insulation to maintain stable temperatures in space; propulsion thrusters to control its orbit; antennas for communication; and GPS for positioning. Satellites orbit Earth collecting important data using these internal systems and transmitting it back to ground control stations.

4. Transponder
The “Brain” of the satellite that
Receive and Transmit frequency.

5. Frequency Table
Band Up-link Down-link
C 6GHz 4GHz
Ku 14GHz 12GHz
Ka 30GHz 21GHz

6. OLI – Operational Land Imager
“Collects images of the Earth”

7. TIRS – Thermal Infrared Sensor
“Measures land
surface
temperature and
capture thermal
images”

8. Solid State Recorder
Store images acquired by OLI and
TIRS

9. Multi Layer Insulator
Maintaining the internal
temperature in the
satellite.
Temperature in space is
about in rang -290 to
400 degree celsius.

10. Propulsion System
Thrusters ( tiny
rocket)
Maintains its
proper orbit around
the earth.

11. X and S band Antennas
X-band : Used by
ground control to
talk to the satellite.
S-band :
Broadcasting images.
