Apple’s tech specs for the new iPhone 14 Pro and iPhone 14 Pro Max state that they offer dual-frequency GPS for more precise position monitoring. The new Apple Watch Ultra also supports the capability.
Models of the iPhone 14 Pro, like the Apple Watch Ultra, can pick up GPS signals from satellites using both the traditional L1 frequency and the more recent L5 frequency. Compared to L1 signals, L5 satellites transmit a more sophisticated, more potent signal that can better pass through barriers like buildings and trees. The two signals working together will increase the location accuracy of apps like Maps on iPhone 14 Pro models.
According to the U.S. government, as of June, there were 17 satellites in orbit transmitting L5 transmissions. The government claims that L5 will “present consumers globally with the most advanced civilian GPS signal” when combined with L1. Despite the fact that L5 has been deployed since 2010, according to the government, the signal is still “pre-operational.”
According to Apple’s tech specs, the basic iPhone 14 and iPhone 14 Plus do not support dual-frequency GPS. The GLONASS, Galileo, QZSS, and BeiDou satellite navigation systems are still supported by all four iPhone 14 models.
