Antenna is an important factor:
GPS antennas are used in common GPS products such as handheld, PDA, Bluetooth, G-Mouse, etc.
Source, passive and even omnidirectional antenna, among more than a dozen performance indicators, the included angle (except the 1600 maximum omnidirectional antenna), the number of amplifier dB, impedance range, material, anti-interference ability and module matching determine the performance of the entire product, even There are 2-3 antennas on the plane (both above and below), and some are also well positioned in the car and on the bottom of the car. In other words, the 3rd generation module is very good, and the antenna mismatch may not be as good as the 2nd generation product.
Number of channels:
3 stars two-dimensional, 4 stars three-dimensional positioning, this is the basic principle of GPS, we use it on the ground is 11-12
There are only 12 omnidirectional antennas (because the angle of the antennas is 160 degrees), and there are only 12 omnidirectional antennas. When you reach the sky vehicle (object), you can receive a few more (certain omnidirectional or more than two antennas), but it is also the most to take 3-4 signals from them. The most powerful and nearest effective satellites are used for calculation and positioning. Many military GPS have 5 channels, but only use 4 channels for positioning, and 1 channel quickly searches all visible satellites, and compares them with 4 effective satellites. One is replaced, so that the 4 strongest signal satellites are maintained. Therefore, it is not that the higher the channel, the better. Generally, 12 satellites on the ground are enough. What 16, 18, 20, 24... are all soft channels, which reflect the maximum number of visible satellites that can be searched, and have no practical significance.
