Introduction
Manual Content
- Satellite Link and Outdoor Unit Design
To perform satellite communication over satellite links with sufficient quality the earth sta-
tions have to fulfill specific requirements concerning their transmission power and antenna
gain. A proper network design is based on an estimation of the link properties, taking into
account parameters of the satellite transponder and of the earth stations.
The ND Satcom Link Budget Tool which can be used to calculate satellite link power re-
quirements will be described in this section.The output will be an optimal selection of trans-
mitter and antenna types for each earth station.
