# Dynamic positioning configuration and its first-order optimization

@article{Xue2013DynamicPC, title={Dynamic positioning configuration and its first-order optimization}, author={Shuqiang Xue and Yuanxi Yang and Yamin Dang and Wu Chen}, journal={Journal of Geodesy}, year={2013}, volume={88}, pages={127-143} }

Traditional geodetic network optimization deals with static and discrete control points. The modern space geodetic network is, on the other hand, composed of moving control points in space (satellites) and on the Earth (ground stations). The network configuration composed of these facilities is essentially dynamic and continuous. Moreover, besides the position parameter which needs to be estimated, other geophysical information or signals can also be extracted from the continuous observations…
