Abstract

Generic SATPS receivers and methods for configuring generic SATPS receivers that include a plurality of outputs are provided. These configurable SATPS receivers are adapted to be utilized in at least one of a plurality of particular SATPS receiver applications, and can also include a plurality of input paths, and a means for generating selected ones of the plurality of possible outputs. Selected ones of the plurality of outputs are enabled/disabled based on at least one requirement of the particular receiver application to configure or program the generic SATPS receiver to function as a SATPS receiver used for a particular SATPS receiver application or operating environment. The selected ones of the plurality of outputs can be defined by and can be those utilized by the particular SATPS receiver application or operating environment. Thus, SATPS receivers are provided that can be used in multiple applications, that can accept multiple types of assistance data, and that have multiple types of outputs depending on the application and/or desires of the user. The SATPS receiver can be implemented in SATPS systems that include at least one satellite that provides SATPS information, a generic SATPS receiver, and a remote computer.

Claims

1. A method of configuring a generic Satellite Positioning System (SATPS) receiver for use in a plurality of SATPS applications, the method comprising:

providing a plurality of SATPS input paths to the generic SATPS receiver;

providing a plurality of possible outputs from the generic SATPS receiver that are associated with a position determination of the generic SATPS receiver;

determining a particular generic SATPS receiver application from the plurality of SATPS applications;

selecting at least one desired output from the plurality of possible outputs responsive to the determination of the particular generic SATPS receiver application; and

activating the at least one desired output.

2. The method of claim 1, wherein the particular generic SATPS receiver application is selected from at least one of the group consisting of a wireless communicator application, a laptop computer application, a location services application, a cellular telephone application, and a vehicle navigation application.

3. The method of claim 1, wherein the plurality of possible outputs includes an in-phase output, a quadrature-phase output, and an Intermediate Frequency (IF) output.

4. The method of claim 1, wherein the step of activating the at least one desired output is implemented utilizing software, hardware, or firmware.

5. The method of claim 1, wherein the generic SATPS receiver is configurable for use with a Global Positioning System (GPS) satellite network.

6. A method of configuring a generic SATPS receiver for use in any of a plurality of particular SATPS receiver applications dependent upon an operating environment in which a particular SATPS application operates, the method comprising:

providing a plurality of input paths to the generic SATPS receiver;

providing a plurality of possible outputs from the generic SATPS receiver; and

enabling selected input paths and selected possible outputs based on requirements of a predetermined particular SATPS receiver application.

7. The method of claim 6, wherein the plurality of possible outputs includes an in-phase output, a quadrature-phase output, and an Intermediate Frequency (IF) output.

8. The method of claim 6, further including the steps of:

generating radio frequency (RF) outputs based on the plurality of input paths; and

extracting data from selected ones of the RF outputs and other inputs;

selecting desired outputs from the plurality of possible outputs; and

generating the desired outputs to be utilized by the predetermined particular SATPS receiver application.

9. The method of claim 8, wherein the RF outputs are generated by an RF unit.

10. The method of claim 8, wherein the other inputs are selected from at least one of the group consisting of a coarse position input, a navigation data input, a Doppler input, a time input, a frequency reference input, a universal time code (UTC) correction input, an ionospheric input, an ephemeris input, an almanac input, and a satellite ID input.

11. The method of claim 8, wherein the data is extracted from the selected ones of the RF outputs and the other inputs by a baseband unit.

12. The method of claim 6, wherein the particular SATPS receiver application is selected from at least one of the group consisting of a wireless communicator application, a laptop computer application, a location services application, a cellular telephone application, and a vehicle navigation application.

13. The method of claim 6, wherein selecting the ones of the plurality of the possible outputs is implemented utilizing software, hardware, or firmware.

14. The method of claim 6, wherein the generic SATPS receiver is configurable for use with a Global Positioning System (GPS) satellite network.

15. A method of configuring a generic Satellite Positioning System (SATPS) receiver for use in a plurality of SATPS applications, the method comprising:

providing an input path to the generic SATPS receiver for SATPS satellite signals;

providing at least one input path to the generic SATPS other than the input path for the SATPS satellite signals;

providing an output path from the generic SATPS for outputting position;

providing an additional plurality of outputs dependent upon the operating environment in which a particular SATPS application operates;

providing at least one additional output path, wherein signals on the at least one additional output path are returned to the input paths;

testing the input paths and the outputs paths; and

selecting a specific configuration of the input paths and the output paths used by the generic SATPS receiver based on the testing.

16. The method of claim 15, wherein the additional plurality of outputs includes an in-phase output, a quadrature-phase output, and an Intermediate Frequency (IF) output.

17. The method of claim 15, wherein the step of testing the input paths and the output paths is implemented utilizing software, hardware, or firmware.
