Is the Redmi Note 12 Turbo a single frequency GPS

With the continuous development of mobile phones, there are more and more functions on the phone. In addition to communication and entertainment, the positioning function on the phone is also very important. If the positioning is not accurate, it will cause considerable trouble to everyone's daily life. In order to have more precise positioning, the vast majority of mobile phones now use dual band GPS. So, is the Redmi Note 12 Turbo single band or dual band GPS?

Is Redmi Note12Turbo a single frequency GPS? Is Hongmi Note12T a single frequency GPS or dual frequency

It is a single frequency GPS

GPS is divided into single frequency receivers and dual frequency receivers based on the carrier frequency of the receiver. Single frequency GPS can only be accurate to 5 meters, while dual frequency GPS can be accurate to 3-5 meters. Dual frequency receivers can eliminate ionospheric effects and make positioning more accurate. The dual frequency global positioning system can simultaneously receive L1 and L2 carrier signals. By utilizing the difference in ionospheric delay caused by dual frequency, the impact of ionospheric delay on electromagnetic wave signals can be eliminated. Therefore, dual frequency receivers can be used for precise positioning of thousands of kilometers. Most flagship smartphones on the market now use dual frequency GPS solutions.

Whether it is a single frequency GPS or dual frequency GPS configuration, it cannot be seen from the appearance of the phone, and can only be viewed and recognized from the parameter table. The so-called dual frequency GPS function refers to the detailed annotation after GPS in the phone parameter table, usually labeled as "GPS (L1 L5)" or "GPS (L1/L5)".

According to the official configuration released by Redmi, the Redmi Note 12 Turbo is indeed a single frequency GPS, rather than the commonly used dual frequency GPS. Overall, the accuracy of positioning is much lower than that of dual frequency GPS, but the difference is not significant for daily use.
