Antenna Selection to Minimize Pointing Requirements

Use of antenna optimization to ensure antenna pointing requirements are kept to a minimum
Technical Feature Antenna Selection to Minimize Pointing Requirements Traditionally, when designing a satellite communications system, an allowance is made in the link budget for pointing loss. The earth station's antenna size is then selected to achieve the desired gain margin. In this article, a different approach called antenna optimization...
