To better understand your Bluetooth GPS, please read Chapter 2 before using Bluetooth GPS. GPS signal receiving global positioning system (GPS) is a space-based radio communication navigation system. This system includes the ground control center and 24 satellites. These satellites orbit the earth at an altitude of 17500 km from the ground. Each satellite is distributed in six orbital planes and orbits the earth twice a day. The whole satellite system transmits time information and precise positioning information 24 hours a day. Bluetooth GPS provides users with services including location, speed, sailing time and want to know their geographical position anytime and anywhere. Bluetooth GPS provides high-precision positioning and first positioning according to the environmental conditions of the positioning receiver and the initial position of the positioning receiver. During the positioning process, the receiver needs to track the satellite for at least 3 minutes, and calculate the position of the equipment by using the received signal and the data in the digital memory of the receiver. Environmental factors affect the accuracy of positioning and the first-time positioning, including protecting high-rise buildings, streets and corridors, huge plant cliffs and other obstacles that block satellite signals and lack satellite geometric positioning. The initial position of the receiver refers to the nearest position memorized by the receiver, which can largely measure the time of "first positioning". The hot start time is 10 second, the cold start time is 80 seconds, or it takes at least 3-5 minutes to restart, such as flying 500 kilometers from the starting point. Bluetooth GPS uses the triangulation method of satellite signal power to calculate the accurate measurement distance, and it is enough for people who want to know the approximate position to choose the exact circle probability error (SA) in the range of 10 meter. Subsequently, the receiver converts the data and position information measured based on GPS(WGS84) into the corresponding longitude and latitude. The position deviation is tens or even hundreds of meters, which eventually leads to the use of wrong data. In addition to the use of data, there will be many positioning errors, which limit the accuracy. The main errors include satellite operation error, inaccurate satellite geometric positioning, multi-channel signal, atmospheric occlusion and receiver total timing. For a detailed description of GPS signals, please refer to Chapter 3 "Detailed Description of Bluetooth GPS Operation". Use an optional external antenna When you use Bluetooth GPS in an indoor environment where satellite signals are shielded, we recommend that you use an optional external antenna for your convenience. (Optional component) Please refer to the operation chapter for detailed operation methods. Determine the optional external antenna for EMTAC support. Using unqualified antenna will seriously reduce the positioning accuracy and even damage the receiver. Please refer to the basic usage before using the optional external antenna. Note: Bluetooth GPS has a built-in rechargeable lithium-ion battery specially designed for its circuit. Precautions for use are as follows: L. Only the charger provided by Bluetooth GPS is allowed. Using other chargers will damage Bluetooth GPS and even cause explosion. Don't put the Bluetooth GPS in an environment higher than 60℃- 140℃, such as exposure in the car. Exposure of Bluetooth GPS to high temperature will not only shorten the life of electronic components, melt or cover some plastics, but also destroy the built-in battery of Bluetooth GPS and even cause an explosion. L. Don't open or destroy the receiver easily. There are no other components in the receiver. The warranty for opening the receiver is invalid.
