Currently the practice of constructing various algorithms of inertial navigation, including strapdown navigation system (SINS), indicates that two mathematical methods for describing rotation are mainly used: using quaternions or direction cosines. Moreover, in SINS algorithms it is often convenient to use two of these parameter systems in parallel: quaternions for the angular motion algorithms (the...
The article proposes a system for removing space debris from the geostationary orbit (GEO). The system is based on advanced space solutions and rational scheme of collecting space debris by reusable automatic long-use space vehicles. Creation of such a system will probably encourage a number of innovative space technologies such as reactive motion with high specific impulse, interorbital transfers...
