Autonomous hardwired tracking loop coprocessor for GPS and WAAS receiver

An autonomous hardwired tracking loop (HWTL) radio receiver system comprising:

• a correlator engine, the correlator engine receives an IF signal and provides correlation operations to generate a correlated data output;
• a CPU;
• and
• a HWTL coprocessor coupled between the correlator engine and the CPU to direct passage of data via one or more on-board memory components to the correlator engine or the CPU, wherein the one or more on-board memory components comprises storing a set of parameters associated with data tracking and acquisition operations.

An autonomous hardwired tracking loop method (HWTL method) for a radio receiver system having a correlator, a CPU, and a HWTL coprocessor, wherein the HWTL method comprises:

• providing signal processing functions requiring greater than 1 KHz frequency rate by the correlator;
• providing receiver processing comprising data acquisition and tracking function processing by the HWTL coprocessor;
• and
• providing navigation and non-radio receiver operations by the CPU.

An apparatus for acquiring and tracking signals received from a plurality of GPS transmitters, comprising:

• an engine for correlating the signals received from the plurality of GPS transmitters;
• and
• a subsystem communicatively coupled to the engine, the subsystem configured to acquired and track the correlated signals, the subsystem including:
• a subsystem processor, implementing at least one software module that acquires and track the correlated signals according to instructions stored in a memory communicatively coupled to the processor, wherein the instructions include at least one operation implemented in a circuit module.
