CONTROLLING FAST ACQUISITION HARDWARE TO PRE-POSITION A SATELLITE TO CONSTRAIN BASEBAND SEARCHES

摘要

A system of searching for and acquiring a satellite signal comprises a system controller, a receiver controller operatively coupled to the system controller and configured to identify one or more satellites for which a search is to be conducted, and a fast acquisition module in operative communication with the receiver controller. The fast acquisition module is configured to receive a satellite search request from the receiver controller and divide the search request into a plurality of smaller search space requests. A hardware search device is in operative communication with the fast acquisition module. The hardware search device is configured to conduct a search for a satellite based on one or more of the search space requests and send search results back to the fast acquisition module. A baseband processor is operatively coupled to the receiver controller and configured to track one or more satellites based on the search results.
