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?
27 Σεπ 2021 · I need to compute the footprint (ground area that its transponders offer coverage) of beam diameter. Given different frequencies, distance between a satellite and ground station. I have found the same calculation: it was presented by mynaric. Could someone explain how the beam sizes were computed?
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
20 Ιαν 2022 · This problem has two parts. 1) Set up the geometry properly so that for a given lat/lon one can calculate the point in the antenna gain pattern and 1/r2 1 / r 2 to get the power at the Earth's surface, and 2) Generate contours.
