Nevertheless, that could still result in an overall improvement to the results you saw in Apple Watch 6. In itself, this gives more chanceof achieving the same level of accuracy as before. We know for certain that the new Apple chip gets additional global coverage from the addition of the Chinese Beidou constellation of satellites. Number of satellite frequencies used (L1, L5).Quality of smoothing or sampling algorithms.Available number of satellites (from one or more constellations).
GNSS Accuracy is a highly complex subject and these factors all come into play Must Read: GPS Tests of ALL Sports Watches & MethodologyĪpple Watch 7 – A New Generation of GNSS/GPS Accuracy…and Power My sneaking suspicion (guess) would be that the hardware did NOT change because my extensive GPS tests of the Apple Watch 6 ( supporter-only content) found little difference to what came before – but that’s fine as the results were pretty good and better than almost all current sports watches from Garmin, Coros, Polar & Co. It’s quite possible that the Series 6 GPS chip was silently updated around 2019 as there were many technical advances from other GNSS chip manufacturers in the wider market at the same time. Support for the Galileo and QZSS constellations were added in Apple Watch Series 3 but then we don’t know what happened to the tech as the support for the same constellations was maintained from 2017 to the Apple Watch 6 in 2020. Series 2 saw the introduction of a GNSS chip for the first time which covered both the American global GPS network as well as the Russian GLONASS network. The first-generation Apple Watch and Series 1 Apple Watch had no GPS capability.
