Systems and methods for scalable GNSS acquisition and tracking

1. A receiver device, comprising:

an acquisition engine using a first circuit size, the acquisition engine configured to receive a first signal including a plurality of first satellite vehicle signals, the acquisition engine configured to identify a first satellite vehicle based on the first signal;

a reconfiguration engine configured to receive an indication that the acquisition engine identified the first satellite vehicle, and responsive to receiving the indication, generate a reconfiguration file defining a second circuit size less than the first circuit size and cause the acquisition engine to be reconfigured based on the reconfiguration file to use the second circuit size; and

wherein the second circuit size corresponds to a number of logical elements used by the acquisition engine and is determined based on a time uncertainty parameter for identifying a second satellite vehicle.

2. The receiver device of claim 1 , wherein the acquisition engine is implemented using a field programmable gate array (FPGA), and the reconfiguration engine is configured to cause the FPGA to execute FPGA partial reconfiguration based on the reconfiguration file.

3. The receiver device of claim 1 , further comprising a first tracking channel configured to track the first satellite vehicle identified by the acquisition engine.

4. The receiver device of claim 1 , wherein the receiver device is configured to reduce power usage by logical elements used with the first circuit size and not used with the second circuit size.

5. The receiver device of claim 1 , wherein the acquisition engine is further configured to use the second circuit size to receive a second signal including a plurality of second satellite vehicle signals, and identify a second satellite vehicle based on the second signal.

6. The receiver device of claim 5 , wherein the plurality of second satellite vehicle signals includes at least one of the plurality of first satellite vehicle signals.

7. The receiver device of claim 5 , further comprising a second tracking channel configured to track the second satellite vehicle identified by the acquisition engine.

8. The receiver device of claim 7 , wherein the second tracking channel is configured to use logical elements used with the first circuit size and not used with the second circuit size.

9. The receiver device of claim 1 , wherein a static portion of the signal acquisition and tracking device includes the reconfiguration engine.
