Total greenhorn here, please be gentle! Using the Sat Look Angles Heading Calc linked on the site here to determine Long, Lat, Elev, etc. I'm a bit confused on what the little green and red pointer bubble(s) indicate? As well as the d=150.0 ft and h=103.1 ft. I'm assuming (big assumption) that's indicative of distance and height, but distance and height from what? Can anyone help
