Yes, all GPS work best when moving (I am not sure but I think the Astro MUST be moving for the compass to be correct, been a while since I read the manuel though). If you are not moving it is having to average the sattelites etc and it is missing one piece of info, you moving.
While most times you don't have to recalibrate it unless you change batteries etc, it is technically possible to have to recalibrate it every time you turn it off and back on.
Mine doesn't get off that much, about the only time I have to recalibrate it is when I change batteries, but technically I think you are supposed to calibrate the compass every time you turn it on (I do leave mine on all the time with the backlight off).
