Description:
CE Desktop SAT shows, before a satellite terminal is installed, where it will see the sky it needs. It is the satellite module of CE Desktop for ArcGIS Pro. Operators, integrators, defence and public safety teams and utilities use it to decide which locations will work, above all in an area the planner has never visited, where a tree line, a slope or a building can block the view. A geostationary (GEO) dish needs one clear path to its orbital slot. A low Earth orbit (LEO) terminal hands over between satellites that cross the whole sky, so it needs a wide clear field of view above its minimum elevation. A GNSS receiver needs many satellites spread around the horizon. The Sky Clearance tool produces rasters over a chosen radius, from a point clicked on the map or a ground station. At every pixel it checks the full 360 degrees around the terminal against the terrain and the heights of buildings and vegetation. In GEO mode the result is the clearance angle towards the satellite, in LEO mode the percentage of usable sky that is open, and in GNSS mode the angle above which the sky is open in every direction. GEO and LEO runs also give an indicative throughput raster. Ground stations store band (C, Ku or Ka), EIRP, G/T, polarisation, frequencies, bandwidth, minimum elevation and required C/N, and satellites are kept as templates. Stations are placed by click or coordinates, in batch from a point layer, or from ModelBuilder and ArcPy with the CE.pyt toolbox. The Quick SAT Link Budget tool calculates the downlink: look angles, slant range, free-space loss, gaseous attenuation to ITU-R P.676, rain, cloud and scintillation to ITU-R P.618, C/N0, available and required C/N and the margin. Results sit in the same workspace as terrestrial predictions, so satellite and terrestrial links are compared on one map.
