Mao, X. (author), Visser, P.N.A.M. (author), van den IJssel, J.A.A. (author)Baseline determination for the European Space Agency Swarm magnetic field mission is investigated. Swarm consists of three identical satellites -A, -B and -C. The Swarm-A and -C form a pendulum formation whose baseline length varies between about 30 and 180 km. Swarm-B flies in a higher orbit, causing its orbital plane to slowly rotate with...journal article 2019

(author), Jäggi, Adrian (author), Mayer-Gürr, Torsten (author), Sebera, Josef (author), Visser, P.N.A.M. (author), Zehentner, Norbert (author)It is of great interest to numerous geophysical studies that the time series of global gravity field models derived from Gravity Recovery and Climate Experiment (GRACE) data remains uninterrupted after the end of this mission. With this in mind, some institutes have been spending efforts to estimate gravity field models from alternative...journal article 2016
