What frequency is GLONASS?
What frequency is GLONASS?
1602 MHz
Traditionally, GLONASS satellites transmit navigational radio signals on two frequency sub-bands (L1 ~ 1602 MHz and L2 ~ 1246 MHz), relying on the Frequency Division Multiple Access (FDMA) technique in contrast to CDMA employed by all the other GNSS systems.

How do I make my iPhone GPS more accurate?
To improve GPS accuracy:
- Make sure that you’ve set the date, time, and time zone correctly on the device in Settings > General > Date & Time. If possible, use Set Automatically.
- Keep a clear view in several directions.
Does iPhone 11 use Glonass?
The GNSS includes coverage from GPS, the Russian Global Navigation Satellite System (GLONASS) and BeiDou. Given that the iPhone 11 lineup’s technical specifications do not directly mention BeiDou support, Apple’s statement likely covers support for the network through the GNSS.
