Navagation processing between a tracker hardware device and a computer host based on a satellite positioning solution system

摘要

Methods and systems consistent with the present invention provide a host based positioning system. The host based positioning system includes a tracker hardware interface that connects to a dedicated hardware space vehicle tracker to a host computer. The tracker hardware interface receives positioning information from the space vehicle tracker and communicates with the host computer using predefined messages. The host based positioning system includes a layered protocol approach to enable user applications on a host computer to access data from tracker hardware device.
