<p>An apparatus, method, and system for predicting subframes of GPS signals. The apparatus includes a processor capable of determining whether a subframe is an almanac subframe, setting a timehead and adding it to a TOW, setting a TLM message based on a value of the TOW, generating a CRC for a predicted subframe, and a memory for storing the predicted subframe. The memory may vary in size based on the number of predicted subframes. The processor is further capable of determining whether the value of the TOW is less than the number of seconds in a week, calculating a position of the predicted subframe in the memory, and setting a valid flag.</p> |
