Introduction

1.3.4 Antenna Pointing Solution

The position (latitude and longitude) of the mount and the longitude of a selected satellite are required to calculate a pointing vector from the mount to the selected satellite.

Given the mount’s latitude and longitude and the pointing vector to the satellite, the RC3000 calculates the elevation (with respect to local horizontal) required. Feedback from the inclinometer on the elevation axis will be used to move the mount to the required elevation.
