TL;DR: The Swarm SCARF (Satellite Constellation Application and Research Facility) as mentioned in this paper is a three-satellite constellation to study the dynamics of the Earth's magnetic field and its interactions with the Earth system, is expected to be launched in late 2013.

TL;DR: An iterative algorithm for determining density and crosswind from multiaxis accelerometer measurements on satellites is presented, which works independently of the orientation of the instrument in space, and is compared with previously published algorithms using simulated data for the challenging minisatellite payload.

TL;DR: First PSO results from more than one year of Swarm GPS data indicate that the consistency between the reduced-dynamic and kinematic Swarm PSO for most parts of the Earth is at the 4–5 cm level.

TL;DR: The first ESA Earth explorer core mission GOCE (Gravity field and steady-state Ocean Circulation Explorer) was launched on 17 March 2009 into a sun-synchronous dusk-dawn orbit with an exceptionally low initial altitude of about 280 km as mentioned in this paper.

TL;DR: In this article, the acceleration measurements of the Swarm satellites are manually removed using a dedicated software tool, and then the calibrated and corrected accelerations are merged with the non-gravitational accelerations derived from the observations of the GPS receiver by a weighted average in the spectral domain, where the weights depend on the frequency.
