GPS is now so common that we take it for granted, but it is not always perfect, so a new technology may be born in due course. A group of researchers has been considering this issue and proposed a new positioning technology called Locata technology.
Locata can use ground equipment projects in a local area. Its satellite signals reach stronger than GPS. It can also work indoors. Of course, it can also be outdoors. The relevant researchers also claim that it can be reduced, and its reduced receiver can be installed. Into an ordinary mobile phone. In addition, although the United States has invented GPS technology, it signed a contract last month and agreed to test Locata on a large scale at the White Sands missile range in New Mexico. In fact, GPS is usually fighting against the indoor environment and big cities: if there is a towering concrete building, then it will be difficult to get a signal. In contrast, Locata already has transmission accuracy along any axis. 18cm, and it seems that this number can be reduced to 5, which is crazy. Currently, the technology is still in its infancy, and if it is possible to replace GPS at any time, I believe it will gain some impressive performance and marketing.
