Attitude Determination System (ADS) is a process to determine the attitude of a satellite by using on board sensors and attitude estimation algorithms to determine the orientation of the satellite which is relative to inertial reference frame such as Earth reference frame. The ADS is consists of an attitude sensor which provides the attitude and orbital position of the satellite to the Attitude...

The design and performance of the Astrid-2 magnetometer are described. The magnetometer uses mathematical routines, implemented by software for commercially available digital signal processors, to determine the magnetic field from the fluxgate sensor. The sensor is from the latest generation of amorphous metal sensors developed by the Department of Automation at the Technical University of Denm...

A small vector magnetometer has been constructed for DTUsat – a Danish CubeSat student project at the Technical University of Denmark. The presented magnetometer is used for attitude determination in conjunction with sun sensors, and supply local field measurements for the magnetotorquer controller. Present launch date is June 30th, 2003 from Plesetsk, Russia. Constraints on mechanical size, ma...

Abstract This paper describes and discusses the preprocessing calibration of magnetic data taken by navigational magnetometers onboard two GRACE satellites, with focus on almost 10 years period from January 2008 to end mission in October 2017 for which 1-Hz are available. A is performed comparing raw magnetometer sensor readings model vector values as provided CHAOS-7 geomagnetic field time pos...
