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.

Why it's free to use
- Filed August 7, 2001 and granted April 26, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 7, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 7, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
