Predicting Satellite Reception

[GeoBobC]

Is there a good source of information for predicting GPS satellite configurations at a certain location, at a specified date and time? I've noticed that from day-to-day the reception (and therefore accuracy) I get varies, and have assumed this is due to the satellites' positions relative to the earth constantly changing.

 

If, for example, I knew that satellite reception would be better at 3:00 p.m than at 5:00 pm, then I could plan my outing accordingly to take advantage of the best reception times.

There appear to be a couple of useful tools here.

 

Edit, well, I'm seeing that some of the links that were most useful in the past now seem dead.

Check out this planning software from Trimble. It does exactly what you want to do. It works pretty slick and gives you a lot of flexibility to do different things.
