At present, there are many kinds of GPS receivers on the market, generally including handheld, vehicle mounted, receiver+PDA and other applications. We often see many GPS enthusiast forums where everyone is discussing which device is better and which map is most useful. Next, I will talk about the nature of the use of GPS receivers from my practical experience.
If it is an on-board application, the situation is quite simple. As long as you don't care about spending money, car and PDA can both be used. Because the car is a small room, from the energy point of view, the power supply of this small device can be said to be endless. The use environment is basically the same as the In Door. As long as you have money, you can do everything luxurious - even connect a laptop. However, if we are hiking in the wild, we have to consider many other issues when choosing and using the GPS system.
The most fundamental function of GPS receiver is to calculate the longitude and latitude of the current position by receiving satellite signals (through radio wave Doppler effect). The more signal sources the receiver receives at the same time, the more dispersed the signal sources are in the airspace, and the higher the positioning accuracy. But what's the use of knowing your own longitude and latitude? It once happened that some beginners on foot, carrying GPS systems, entered the no man's land. I thought that with GPS, I would be safe. When I got lost, when I turned on the GPS, the signal was really strong. The machine gave me a pair of numbers, and the details of the road network stored in the machine were also blank. The nearest navigation point was Lanzhou, wasn't it? There is no road in that place. The GPS of several thousand yuan has completely lost its reference value. As a result, the man was out of danger by relying on the compass function provided by GPS. From this example, we can see that although GPS is advanced, it is useless to use it improperly. For the person in distress in the above example, the method of using GPS is fundamentally wrong - GPS cannot tell you where to go.
