Host based satellite positioning systems
View Patent ↗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. The tracker hardware interface receives positioning information from the space vehicle tracker. The host based positioning system also includes a memory that includes a GPS library having a user interface, a tracker interface, and an operating system interface. A processor runs functions provided by the interfaces.
1. A system for processing positioning signals, the system comprising;
a tracker hardware interface configured to receive positioning information including raw GPS positioning data;
a memory comprising a GPS library comprising a user interface, a tracker interface, and an operating system interface, the tracker interface comprising at least one tracker interface function for communicating over the tracker hardware interface and the user interface comprising at least one user interface function associated with a restart mode; and
a processor configured to execute the tracker interface function by transmitting the raw GPS positioning data to a positioning engine configured to determine a position from the positioning data;
wherein the positioning engine is configured to execute on the processor separately from a user program that executes on the processor, the user program displaying location information derived from the raw GPS positioning data.
2. The system of claim 1 , wherein the tracker hardware interface comprises a serial interface.
3. The system of claim 1 , wherein the user interface comprises at least one positioning control function and at least one positioning engine communication function.
4. The system of claim 3 , wherein the positioning control function comprises a positioning engine start function.
5. The system of claim 3 , wherein the positioning control function comprises a positioning engine stop function.
6. The system of claim 3 , wherein the positioning engine communication function is a command delivery function.
