GOCE gradients in various reference frames and their accuracies

Müller, Jürgen (Göttingen : Copernicus GmbH, 2003)

The objective of GOCE (Gravity Field and Steady-State Ocean Circulation Explorer) is the determination of the Earth's gravity field with high spatial resolution. The main science sensor (the gradiometer) measures differential ...
Orbit simulations and optical phase locking techniques for an atom interferometric test of the universality of free fall

Velte, Ulrich (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)

Several aspects of testing the universality of free fall (UFF) with spaceborne atom interferometers are discussed. Theoretical effects that could lead to an (apparent) violation of the UFF are reviewed and the requirements ...
Swarm accelerometer data processing from raw accelerations to thermospheric neutral densities 2. Aeronomy Swarm Science Results after two years in Space

Siemes, Christian; de Teixeira da Encarnação, Joao; Doornbos, Eelco; van den Ijssel, Jose; Kraus, Jiří; Pereštý, Radek; Grunwaldt, Ludwig; Apelbaum, Guy; Flury, Jakob; Holmdahl Olsen, Poul Erik (Berlin : Springer Berlin, 2016)

The Swarm satellites were launched on November 22, 2013, and carry accelerometers and GPS receivers as part of their scientific payload. The GPS receivers do not only provide the position and time for the magnetic field ...
