\"AppleApple is touting the Apple Watch Ultra<\/a>\u2019s dual-frequency GPS support, viz., it uses the GPS L5 band in addition to L1 to improve accuracy. The new L5 signal<\/a> is higher power and is supposed to provide more robust service, but with only 17 satellites broadcasting on it it\u2019s not yet fully operational. Still, a Reddit user was able to document the improved accuracy by conducting an unexpected stress test: mowing the lawn<\/a>. With the Ultra the mowing rows can be made out, whereas the tracks made with a series 4 watch were all over the place. [9to5Mac<\/em><\/a>]<\/p>\n

While the Ultra is the only Apple Watch that can use the L5 band, watchOS 9<\/a> adds a redesigned Compass app and a Backtrack feature that lets users retrace their steps using on-the-fly waypoints and GPS traces. MacRumors<\/em> has a tutorial<\/a>. This is something I\u2019m looking forward to trying out: my series 8 watch arrived last week.<\/p>\n","protected":false},"excerpt":{"rendered":"
