1. The accuracy of the civil GPS positioning terminal is up to 10 meters.
The GPS we are using now belongs to the civilian-grade GPS. We will not discuss the military level for the time being. In the case of GPS , in the case of good signal (under ideal conditions such as open ground and sunny weather), the GPS Phone Tracker accuracy is generally around 10 meters. If it is LBS (base station) positioning, the positioning accuracy is generally between 100 meters and 1000 meters.
The GPS positioning accuracy is achieved by a certain algorithm. The environment requirements at that time are very high. If there are high-rise buildings, interference signal sources, and cloudy weather, the positioning accuracy error will definitely be relatively large. The high precision mentioned in the market can only be achieved under ideal conditions. Even if it is the same machine, the same place, the positioning accuracy is different at different time periods is normal.
2. Not a battery can be used as a long standby GPS positioning terminal.
For the ultra-long standby GPS positioning terminal, the capacity and characteristics of the battery determine the length of the standby time.
We all know that the standby time is proportional to the battery capacity, the capacity is about the same, and the endurance is stronger. Therefore, the battery capacity can be roughly used as a judgment method.
Then not all high-capacity batteries are suitable for such positioning. There are many types of batteries, and there will be self-discharge during normal use, which means that the battery will consume power. If the self-discharge of the battery itself is very high, even the large capacity will not support the concept of long standby.
A very obvious battery that cannot be used for long standby is the polymer battery pack battery. Under normal circumstances, the self-discharge of this battery is very high, you can imagine your own mobile phone battery. Look at how long it takes to turn it on after a month.
