I understand that most devices have 1 Hz refresh rate for GPS positioning. I tried to read about the actual GPS implementation but I could not figure out how often the location can be determined.
Given a custom chip, how often (Hz) the real position of the GPS receiver can be determined using only GPS signal? GPS signal chip (/bit) length is around 1 µs. Would it be possible to compute location every 2-3 chip (/bit) if given enough CPU power (that is, compute again for each time signal changes between 0 and 1)?
