Why is GNSS positioning on the Redmi Watch 5 Active sometimes slow?

GNSS (Global Navigation Satellite System) operates by having satellites transmit signals that are picked up by a receiver, such as a smartphone or watch. The receiver utilizes these signals to calculate its position by measuring the time it takes for the signals to travel from the satellites to the receiver.
GNSS positioning on the Redmi Watch 5 Active is slow due to several factors:
1. If the watch is being used in areas with tall buildings, dense trees, or indoors, the GNSS signal will be obstructed, leading to slower positioning;
2. Other electronic devices or materials like metal can interfere with GPS signals, affecting the speed and accuracy of positioning;
3. Extreme weather conditions or atmospheric interference can impact GNSS signal reception;
4. If the connection between the watch and the mobile phone is unstable, the GNSS positioning will be slow.
