Please Note: If
you are looking for calculations such as G/T, Eb/No, Antenna Gain,
EIRP or C/No then try the 'Useful
Calculations' Pages in our 'Tutorials'
section.
These are the free online satellite link budget calculators. Simply follow the instructions below to use these calculators. We hope that you find these useful and that you
so that you can use them when ever you want.
Instructions:
Fill in the empty boxes within the grey sections and alter any of the existing
parameters to match your system requirements. The blue sections will
be calculated for you. The existing values are not representative
of any particular satellite or antenna but are fairly common values.
By
clicking in a parameter box the original data will be cleared so that
you can easily enter new values.
When
you are ready, click on 'Calculate'.

To obtain values for satellite G/T and EIRP refer to the satellite
footprint specifications. Here is a list of links to some of the available
SES-ASTRA
satellite footprints - use the interactive fleet map to access
the beam contours and EIRP information - and SES-SIRIUS
satellite footprints. See also the LyngSat
website for more satellite beam contour maps. The contours will
show you how much to deduct from the boresight (maximum) EIRP depending
on the antenna locations. The footprint diagrams may sometimes also
state the satellite G/T.
