Investigation of ways to improve positioning accuracy using additional ground means

Currently, the problem of improving satellite navigation systems has gained sufficient popularity. This is due to the fact that a lot of both civilian and military objects are somehow connected with satellites (navigators for civilians, tracking systems in the military sphere, etc.). Unfortunately, when implementing satellite navigation systems in various industries, one has to face a number of problems. Namely, with very low positioning accuracy of the required objects. This is due to the dynamism and mobility of satellites relative to the Earth. That is why stationary ground objects are introduced to improve positioning accuracy. In connection with the above problems, the topic of the work is quite relevant today.
