Why is glonss in the Soviet Union more than 20 years later than gps in the United States? GPS began in 1958 and GLONSS in 1982. At that time, it was beautiful.

I think there are three reasons. First, the problem of vision. At that time, the Soviet Union did not realize the military role of gps, and was still immersed in the advantages of tanks and artillery. In addition, there was little demand for Soviet global operations at that time, and the main battlefield expected by the Soviet Union was in Central Europe. The second is the technical problem. At that time, the Soviet Union did not have such technology, and the third issue was national strength. Before the end of 1960s, the Soviet Union was at a disadvantage in the confrontation between the Soviet Union and the United States, and there were many shortcomings to be made up, which were not worse than gps. At that time, the Soviet Union was trying to develop long-range nuclear power, and others didn't care much. In fact, gps-guided weapons only became popular after laser-guided bombs dominated the world in the late 1990s. The practical significance of early gps is not very great. At present, the second generation is used, and it is transitioning to the third generation. Moreover, although GLONASS started later than gps, the actual networking time was earlier than gps.
