What is the area of the Earth's surface where a satellite signal can be received?

The â??footprintâ?? is the area of the Earthâ??s surface where a satellite signal can be received. The footprint on Earth is determined by the footprint of the antennas on the satellites.


What is satellite footprint?

A satellite footprint refers to the area on Earth's surface where the satellite signal is received. It is the geographical coverage range of the satellite's signal transmission. The footprint size and shape depend on factors like satellite altitude, beam characteristics, and antenna design.


What is a landsat satellite?

A satellite that observes Earth's surface.


What are various satellite sub-systems?

how a satellite can appear to be stationary above the earth´s surface how a satellite can appear to be stationary above the earth´s surface


What is the speed of a satellite signal?

The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.


What are telecommunication links?

In satellite communication, up link refers to the signal traveling up to the satellite while down link refers to the signal coming from the satellite down to earth.


Why doesnt a geostationary satellite trace a path over the surface of the earth?

A geostationary satellite does not trace a path over the surface of the earth because that is what geostationary means - the satellite is stationary over a point on the Earth.


How does the direction of motion of a satellite in circular orbit compare with the curve of earth's surface?

The direction of motion of a satellite in a circular orbit is perpendicular to the curved surface of the Earth. This means that the satellite moves parallel to the surface at a constant distance rather than following the curve of the Earth.


Basic Difference between Active and passive Satellite System?

An active satellite acts as a REPEATER; it amplifies signals received and then retransmits them back to earth. This increases signal strength at the receiving terminal to a higher level than would be available from a passive satellite. A passive satellite only reflects received radio signals back to earth. fr0m: ZIA UR REHMAN D-05-ES-29 DCET Karachi Pakistan.


What is sub satellite point?

A subsatellite point is the point on the Earth's surface directly below a satellite in orbit. This point moves as the satellite orbits the Earth. The subsatellite point is also called the nadir point.


What is the advantage of a helical wire satellite antenna?

Circular polarization characteristics of a helical antenna help offset the effects of spin modulation from satellites in motion, that is, the tendency for satellites to spin causing the position of their antennae to change rapidly in accordance with the spin, causing a fluctuation in the signal as received by a fixed signal on earth. Circular polarization of the earth fixed antenna reduces the fluctuating effects of the satellite's spin on the recived signal.


How do satallites get signals from earth?

Satellites receive signals from Earth using antennas that are pointed towards the ground. The signals are sent from ground stations and relayed to the satellite. The satellite then processes the signal and can transmit it back to Earth or to another satellite.
