All GPS systems cannot receive satellites indoors or the signal is very weak, and can only receive signals outdoors. This is common sense. The correct method for searching for signals is:

　　1. Fix the search signal and do not move around, as GPS is not easy to locate when moving.

　　2. Open the machine to the navigation interface, click on the signal sign in the upper right corner of the navigation interface, and you can see the receiving satellite number map. Normally, 3 satellites are positioned and 5 satellites are navigated; Our satellite navigation GPS can receive stable navigation signals from 7-12 satellites normally, which is enough for you to use.

　　3. Opening the GPS receiver satellite signal module on the upper right side of the back of the machine at a 90 degree angle with the machine provides the best signal reception effect.

　　4. Speed of receiving signals: involves two concepts

　　⑴ Cold start meaning: The first time GPS searches for a satellite is called cold start, which is usually slow.

　　Different GPS search speeds vary, with some GPS cold start searching for satellites within 1 minute, others within 1 minute, around 1 minute to 2 minutes, and some beyond 2 minutes.

　　⑵ Meaning of hot start: Starting again within 2 hours is a hot start, which is the fastest,

　　It usually takes 1-2 seconds to find the satellite. 2-4 hours for warm start
