GPS Amazfit Bip: How it works, how accurate and how to improve the signal

Xiaomi’s Amazfit Bip smartwatch has become a hit among budget fitness trackers thanks to its combination of low price, long-term autonomy and impressive functionality. GPS-It's a module that allows you to track routes without being tied to a smartphone, but how does this technology work in a compact watch case? Why is it sometimes lost and sometimes it takes a few minutes to determine the coordinates?

Many users are asked: How accurate is the GPS In Amazfit Bip compared to professional sports watches?, How often should a module be calibrated? or Can a watch be used for tracking in a forest or a city with tall buildings? GPS In Amazfit Bip, we analyze its technical limitations, compare it with other Xiaomi devices and give practical tips for improving the accuracy of coordinates determination.

If you plan to use the clock for running, cycling or tourism, understand the nuances of the clock. GPS help to avoid disappointments and make the most of the device’s capabilities.

Technical specifications GPS-module in Amazfit Bip

The Amazfit Bip navigation system is based on a Sony chip. GPS (model CXD5603GG), Supports simultaneous connection to multiple satellite systems:

• 🛰️ GPS (The main system providing global coverage.
• 🛰️ GLONASS (Russia improves accuracy in northern latitudes and urban canyons.
• 🛰️ BeiDou (China) – Optimized for Asia Pacific.

The chip is running. A-GPS (Assisted GPS), This means that you can accelerate the positioning by preloading the almanac from satellites over the Internet (when synchronized with the Mi Fit application), which reduces the time of the first signal search from 30 to 60 seconds to 5 to 15 seconds.

It is important to note that the Amazfit Bip uses a single channel. GPS-This means that the device switches between satellites in sequence, rather than tracking them simultaneously. That is why in conditions of poor visibility of the sky (for example, in the forest or between high-rises), the signal can be periodically lost.

⚠️ Note: In the first versions of the firmware Amazfit Bip (until 2019), only the system was activated by default GPS. To improve accuracy, you must manually turn on GLONASS or BeiDou in the settings of the Mi Fit app.

How it's turned on and on GPS At Amazfit Bip

GPS-The module in the watch is activated automatically when you start the activity tracking modes: running, cycling or walking outdoors:

1. The clock doesn't keep a constant. GPS-Monitoring in the background (unlike smartphones) The module is only turned on while training.
2. To save battery power GPS shuts down after 10 minutes without moving (if you, for example, stopped to take a breath).
3. When you first turn on after buying or resetting the settings, the search for satellites can take up to 2-3 minutes - this is normal.

To manually check the work GPS:

1. Go to the menu of the clock: Settings → GPS.
2. Select the Test mode GPS.
3. Wait until the clock finds at least 4 satellites (optimum - 6)+).

If the satellites are not longer than 5 minutes, the problem may be:

• 📵 Bad weather conditions (rain, snow, cloudiness worsen the signal).
• 🏙️ Urban development (high-rise buildings screen the signal).
• 🔋 Battery discharge (at a charge level below 20% GPS may work unstablely).

precision GPS: Comparison with other Xiaomi devices

Based on the results of independent experts’ tests, including channels DC Rainmaker and Wareable, precision GPS The Amazfit Bip can be described as "acceptable for the budget segment, but inferior to the flagship sports watch:

Critical feature of the Amazfit Bip: when driving at speeds above 30 km / h (for example, on a bicycle or in a car) GPS It starts cutting corners at corners, which causes it to be 5 to 10 percent lower in distance travel, and this is due to the smoothing algorithms that are embedded in the firmware.

For comparison, more modern Xiaomi models like Amazfit are more popular. GTR 4 or Xiaomi Watch 2 Pro, using duality GPS-chips (e.g. Sony) CXD5605 or Broadcom BCM47755), Support up to 5 satellite systems at a time and have built-in barometers to adjust altitude.

💡

Before an important training session or competition 10-15 minutes before the start, turn on the Test mode GPS This will allow the module to "warm up" and download current data from satellites, reducing the time to search for a signal when you start recording a track.

Why? GPS Amazfit Bip is not stable: the main reasons

Despite the stated support for several satellite systems, users often complain about:

• 🔄 "Jumping coordinates (the clock shows you running in zigzags).
• ⏳ Long search for satellites (more than 2-3 minutes).
• 📉 Losing signal in the middle of training.

Let’s deal with each problem in detail:

"Jumping" coordinates

It has to do with:

• Low frequency surveys GPS (1 time per second vs. 5-10 times in professional hours).
• The absence of a gyroscope and an accelerometer to smooth the trajectory (only the basic 3-axis accelerometer is used in the Amazfit Bip).
• Energy saving algorithms that turn off GPS split-second.

Long search for satellites

Most often it occurs due to:

• Obsolete almanac (satellite position data have not been updated for more than 7 days).
• Weak indoor signal (if you turn on) GPS at home, not on the street).
• Hardware limitations of the chip CXD5603GG, slow-scanning.

3. Loss of signal

Typical scenarios:

• Passage under bridges, in tunnels or between tall buildings.
• Low battery charge (below 15%).
• Strong clouds or magnetic storms (affect everything) GPS-device).

⚠️ If the clock is constantly losing signal even in open areas, check the integrity of the antenna. GPS. In some batches of the 2018 Amazfit Bip, there was a defect in the soldered connection of the antenna cable, which manifested itself after 6-12 months of operation.

How to improve accuracy GPS In Amazfit Bip: practical advice

While the hardware limitations of the Amazfit Bip cannot be eliminated, accuracy is not a problem. GPS You can make a lot of improvements with the right setup and preparation:

Go out into the open space 2-3 minutes before the start

Insert regimes GPS + GLONASS Mi Fit

Update the watch to the latest version

Charge the battery to at least 50%

Turn off the energy saving mode in the settings of the clock-->

Let’s look at each item in more detail:

1. Optimal settings in Mi Fit

Open the Mi Fit app, go to Profile → Amazfit Bip → Settings of the device → GPS and:

• Activate. GPS + GLONASS (for Russia and Europe; or GPS + BeiDou (for Asia).
• Turn off the option to save charge when GPS (If it is in your version of the firmware).
• Turn on time autosynchronization, which will help the clock find satellites faster.

2. Firmware update

Manufacturer regularly releases updates that improve processing algorithms GPS-To update the firmware:

1. Connect the watch to the Mi Fit.
2. Go to Profile. → Amazfit Bip → Firmware update.
3. If a new version is available, install it (the watch must be charged at least 50%).

The latest firmware versions (starting at 1.1.6.00) include:

• 🔄 Improved algorithms for noise filtering GPS.
• ⚡ Optimizing energy consumption during long-term training.
• 📡 Galileo satellite support (European system).

Calibration of compass and accelerometer

Although the Amazfit Bip does not have a complete compass, calibration of the motion sensors helps improve the accuracy of the distance calculation:

1. Go to Settings. → Sensors. → Sizing.
2. Place the clock on a flat surface and wait for the process to be completed.
3. After calibration, do not wear the watch immediately - wait 1-2 minutes.

Comparison with alternatives: should we switch to another model?

If you are not satisfied with accuracy GPS In Amazfit Bip, you should consider more modern models from Xiaomi or other brands. Below is a comparison table of key characteristics:

If you want maximum accuracy for professional training, it makes sense to consider:

• 🏃 Amazfit GTR 3 or GTS 3 – Best Price/Quality Rate Among Xiaomi Devices.
• 🚴 Xiaomi Watch S1 Pro - flagship with dual GPS barometer.
• 🏔️ Garmin Forerunner 55/245 — standard of accuracy for runners and triathletes.

If you are satisfied with the error in ±5 meters and up to 22 hours of autonomy, the Amazfit Bip remains a great choice for amateur training.

💡

For most users, the difference in accuracy between the Amazfit Bip (±5 m) and flagship models (±The main advantage of expensive watches is the stability of the signal in difficult conditions (forests, cities), not absolute accuracy in open areas.
