Abstract
An method and apparatus and method for determining the position of a satellite overhead by a user using portable computation equipment. The invention uses a portable computational equipment that can be as small as a digital wristwatch or portable computer. Data concerning satellite position is calculated using more robust calculation equipment such as PC and the like. The information on satellite location and timing is downloaded from the PC to the portable calculation equipment for later access in the field by the user. In an alternate embodiment, the orbital determinations can be downloaded to a remote unit for playback in the field.
