What is a "Dual Band Gps Phones"? The Most Authoritative Explanation.
What is dual-band GPS?
This results in a signal that has great anti-interference properties and contains the minimum amount of noise. Simply put, the dual-band GPS uses two frequency bands instead of one, and a superior (L5) band with a standard (L1) band results in a highly accurate GPS positioning solution.What is the difference between single-frequency and dual-frequency GPS Phones?
Single-frequency GPS phones can only receive satellite signals transmitted on the L1 frequency band, while dual-frequency GPS phones can receive satellite signals from both L1 and L5 frequency bands. Currently, the GPS, Galileo, and QZSS satellite systems broadcast civil signals in the L5 band, which are GPS L5C, Galileo E5a, and QZSS L5 signals.What is dual frequency GPS receiver?
So, the devices which are using L1+L2 or L1+L5 bands are called dual-frequency GPS receivers. How is Dual Frequency GPS Better?How many frequency bands are used in GPS?
Answer: The GPS system mainly uses two frequency bands: L1 and L5. Single-frequency GPS phones can only receive satellite signals transmitted on the L1 frequency band, while dual-frequency GPS phones can receive satellite signals from both L1 and L5 frequency bands.
