Hello, I am designing an extremely high gain system, it will be using a parabolic antenna.
The question I wanted to ask is what is the narrowest beam width that the antenna tracker can support? Lets say the sUAS is about 1 km out before it needs to use the dish.
This way I will be able to choose the correct sized dish, I fear too narrow of a beam and the tracker could easily miss!
In short how accurate is the antenna tracker in degrees?
Don't worry about refresh rate, because the extreme gain could be used after 4 kilometers as well, via diversity.
You need to keep all this in mind when designing your tracker.
From my personal experience using a Pixhawk and Servo City mechanism is that it always looks like it is right on. So it’s easy to get a fairly accurate setup.
What is your beam width?
Are you sure you need a dish? There are guys flying 50 Km by only using an inexpensive high rain antenna. How far are you planning on flying?
Dragon Link is a good example, you should review that thread. http://www.rcgroups.com/forums/showthread.php?t=1518533
