What is Circularly Polarized GPS on Amazfit GTR and GTS 4?

GPS on a smartwatch provides accurate activity and location tracking with information like distance traveled, steps counted, calories burnt, etc. Taking an industry-first step in the same direction, Amazfit recently introduced the GTS 4 and GTR 4 smartwatches with a new dual-band circularly polarized GPS. Here’s what circularly polarized GPS on Amazfit GTR 4 and GTS 4 is and how it differs from the regular one.

Dual Band Circularly Polarized GPS Antenna

What is Circularly Polarized GPS?

The circularly polarized GPS is an advanced antenna system that provides a close-to-real navigation experience. The circularly polarized antenna rotates in a spiral pattern, making one rotation during each wavelength. This regulates energy in every plane direction, including vertical and horizontal.

GPS on Smartwatch

This GPS can send signals to the device from any direction, anywhere, more precisely. Since it can send signals in every plane, if the signal is not reflecting on a plane, it transfers the signal to another plane and completes the navigation.

The Amazfit GTR 4 and GTS 4 have industry-leading six satellite dual-band circularly polarized GPS antenna technology introduced for the first time in the smartwatch industry.

This GPS technology is similar to the one used in the aircraft and automotive fields. Because of this, it provides stronger positioning, which is 99% accurate as the top handheld GPS locators in the open air.

The circularly polarized GPS on these Amazfit smartwatches works seamlessly whether hiking on a tree-covered trail or cycling through a congested city. You won’t experience disturbances in positioning by environment and multi-path interference.

Advantages of Circularly Polarized GPS on a Smartwatch

The circularly polarized GPS on Amazfit GTR 4 and GTS 4 is highly beneficial; let’s have a look at some of its advantages:

  • All Plane Signals
  • 99% Accurate as Top Handheld Locators
  • Seamless Navigation
  • Stronger Signal Strength
  • Unimpeded Positioning

Circularly vs. Linear Polarized GPS: The Difference

Most traditional smartwatches with built-in GPS currently rely on linearly polarized GPS. It has two sides, vertical and horizontal. When the electric field signals are perpendicular to the earth, it is known as vertically linearly polarized GPS.

This GPS sends signals in two planes only, i.e. vertical and horizontal. Because of this, it skips sending GPS signals to the watch if it is outside the direction of these two planes.

Whereas circularly polarized GPS can send signals in every plane. It works in a spiral movement when a signal is sent through antennas. It can send the signal to the watch in any direction as it changes the plane if something is between the device and the signal.

Comparing both, we see that the circularly polarized GPS has more reliability, accuracy, and signal strength than the linearly polarized GPS, which travels only horizontally or vertically. Let’s have a quick look at some major differences between both with the table below:

What Else Do You Get on Amazfit GTS and GTR 4?

Apart from the advanced GPS, the Amazfit GTS 4 and GTR 4 smartwatches also support NavIC. It is a GPS alternative designed by ISRO. India has placed eight satellites in the sky, covering the whole Indian continent and up to 1,500 beyond the country’s borders.

As a result, NavIC outperforms GPS and GLONASS when it comes to location positioning in India. Apart from this, both smartwatches have over 150 sports modes with automatic recognition for strength exercises.

They get large AMOLED displays, Bluetooth calling support, built-in music storage, a PeakBeats workout status algorithm, and improved BioTracker 4.0 health sensors. The GTR 4 offers up to 14 days of battery life, while the GTS 4 is claimed to last up to 8 days. Both watches also have Alexa onboard.

Wrapping Up

This was all about the circularly polarized GPS on Amazfit GTR 4 and GTS 4. These are the first smartwatches to bring this GPS technology into the smartwatch industry and offer more accuracy compared to ordinary linearly polarized GPS smartwatches.
