Work out the size of transmit and receive antennas needed on the satellite using the antenna beamwidth calculator link at the top of this page. Hint: Point the beam down at the sub-satellite point to verify its diameter and, if elliptical, the shape and orientation.
3 Φεβ 2021 · I was wondering, how is a satellite's footprint calculated mathematically and what needs to be considered when calculating it?
The most popular geosynchronous orbit satellites with coverage footprint maps including high resolution images, payload frequency plans, transponder data and spacecraft operator information.
The purpose of many satellites is to observe or communicate with points on Earth’s surface. Such functions require a line of sight that is neither too long nor too oblique, so only a certain segment of Earth will be covered by a satellite at any given time.
The satellite’s coverage area on the Earth depends on orbital parameters. Ground stations (GS) can communicate with LEO (Low Earth Orbiting) satellites only when the ground station is under coverage area (satellite footprint) as presented in Fig. 3. The duration of the visibility and consequently the
Methods for calculating footprints for idealized models of several common types of transmitting antennas (circular aperture, elliptical aperture, rectangular aperture, and helical beam antennas), and for antenna beams of specified but rather arbitrary shape are described.
on the satellite, our formulas can be used to generate footprints when the cone corresponding to a particular constant relative power density has essentially any specified shape.
