????1. GPS chip
????The accuracy and algorithm of receiving satellite signals are the key to the accuracy of navigation. The satellite reception performance is mainly determined by the GPS chip. The GPS chip is equivalent to the CPU of a computer. Now the mainstream is the third generation of Sirf chips. It has 20 satellite channels (the second generation of sirf has 12 channels). Others are sony chips and Swiss RFMD chips. The effect of these chips in practical use is obviously different from that of sirf.
????2. GPS power
????When people use GPS, they are usually in the car or outdoors, and sometimes the navigation time is relatively long (such as long-distance travel). Therefore, when selecting GPS, pay attention to the power supply or battery capacity of GPS.
????For the car, the general Bluetooth GPS and all-in-one machine have car chargers.
????When hiking, the battery design ideas of each product are different: some use batteries that are common to Nokia batteries, so that Nokia mobile phone users have many batteries in reserve. Some use large capacity batteries. Some are simply equipped with external dry battery boxes.
????All of these can solve the power problem. The key is which one is more suitable for you.
????3. GPS antenna
????The GPS antenna can enhance the acceptance ability and expand the acceptance range at the same time. For example, if there is no signal in the room, the antenna can guide the outside.
????The GPS of sirf three generation chips does not use GPS antenna in most cases. In the car with metal film, it is generally unnecessary. However, under special circumstances, such as bad weather conditions and high-rise buildings blocked, you can purchase the antenna as a backup. When the signal is good, installing an antenna can also improve the signal strength.
????4. GPS Product Features
????It can be said that every GPS product will have its focus when it is designed. A product cannot be perfect. For example, some machines focus on cost performance, some focus on small, fashionable and beautiful, some focus on functional diversity, and some use large capacity batteries.
