TheApple Watch Ultrais packed with features , but its dual - ring , L1 and L5 GPS sign compatibility are easy to overlook . That may be partly because most people know very small about GPS signal standards , so it ’s essential to see how worthful this addition is and what it means to potential possessor of this beefy , newApplesmartwatch .
GPS standard are not the sexiest thing about expensive smartwatches . Society discussessmartphonesignals quite promptly as everyone argues about the promotion of5Gtechnology they likely do n’t know already exists in their neighborhood . There ’s nothing nearly as dissentious hap in the world of GPS communicating standards , but part of that is also because much of the standardGPS spectrum is n’t availablefor civilian use .

At its inwardness , the important matter to know about GPS as it ’s implemented in smartphones is most phones habituate the L1 signal . L1 has been around the longest and is the most predominant . The sign is split into two part : the atomic number 15 - code for military enjoyment and the C / A - computer code for civilians . As expected , the P - code is more accurate than the civilian sign , which contribute to the ineffectiveness of phone GPS , leading to those annoying " recalculating " mo . This leaves room for L5 , the fresh standard , to ill-treat in and ameliorate the accuracy of civilian GPS . It can be faster , less prone to interference , andeven need less powerwhen projected over foresighted distance than L1 . While the advantage of L5 GPS are percipient , the reveal that it ’ll be pack intoAppleWatch Ultra is mostly just a fancy marketing instruction at this stage .
What L5 GPS Brings to Apple Watch Ultra
L5 is still in its infancy , and as such , it ’s effectively useless on its own . The three-fold - band frequency option of Apple Watch Ultra addresses this by using L5 and L1 simultaneously to produce the most honest GPS readings on the market today . It ’s deserving noting , though , thatiPhone 14 Proand multiple other smartphones have this exact implementation , so this is also another case of Apple infamously introduce a feature while implying it ’s brand new . There are certainly moreuseful Apple Watch Ultra featuresthan this .
Still , there ’s no negative to having dual - stria Global Positioning System on a gimmick , and it ’s good on a smartwatch … potentially . Apple ’s example use case makes gumption , at least . stolon vie in a marathon are typically surround by skyscraper which are known to cause hitch with L1 signals . moreover , there are highly rural areas where L5 has coverage and L1 does n’t , so this fits in with Apple ’s focus onkeeping users connect in emergencies . Dual - band GPS gimmick could mitigate those issues . Ultimately , give that a special identification number of GPS planet are in orbit anyway , all devices will finally move to implementing both signals or sticking with L5 exclusively , soApple Watch Ultrais slightly in the lead of the curve .
