1、 GPS antenna cannot be 100% positioned.
Because unlike mobile radio, GPS antenna can receive signals everywhere, and many things will affect its reception, including satellite distribution status, buildings, viaducts, radio waves, leaves, thermal insulation paper, etc. there are really too many things affected; Generally speaking, looking up from the GPS position, the area of the sky can be seen is the area where the GPS antenna can receive signals.
Because the satellite status is different every day, maybe in the same place, the reception will be full in the morning, but it is impossible to locate at night. These situations are possible, or the positioning status may be bad for several days in a row, so don't rashly decide whether the GPS antenna is good or bad.
2、 Compare the quality of GPS antenna.
To compare the quality of GPS antenna, we must compare it in the same place at the same time. Many people will think that the one used before is better when they buy it, but this is not necessarily correct, because the final result is much worse when they use it in different time and place. They must use it for a long time or at the same time and place to feel the differences between the two GPS antennas.
3、 What are the precautions when purchasing GPS antenna?
The GPS receiving strength is not enough to be used as a reference for the purchase of GPS antenna. When buying, you will only look at the receiving table in the electronic map. The current GPS antenna has false signals or simulated signals in order to make the receiving table look good, resulting in inaccurate positioning or incorrect display.
There is no GPS for indoor positioning. Basically, if there is no signal in the room, there is no signal. The real indoor positioning should be in the room from cold start, but it is the real indoor positioning if it can be positioned. However, basically, the indoor positioning has no meaning at all, because I can't navigate at home.
To buy GPS antenna, you don't need to choose the brand, but you can choose the chip used internally. There are many GPS antenna manufacturers in the market. Choosing manufacturers only considers after-sales service. It is not necessarily the best for large manufacturers to receive information. Generally speaking, there will be no great difference in the effect of GPS antenna with the same chip made by different manufacturers. Therefore, when purchasing GPS antenna, you can choose it according to GPS receiving chip, rather than business brand or GPS antenna price.
4、 Inaccurate positioning is not necessarily the fault of GPS antenna.
Basically, the positioning error of GPS antenna can be within 20 meters. In addition, there may be many reasons why the GPS position is not very accurate, which may be caused by poor reception. There may be a problem with the map data or a wide road. Therefore, it seems that the GPS positioning is offset from the road surface. After a long time, you will know whether it is GPS or map.
