Automating Mission Scheduling for Space Based Observatories
In this paper we describe the use of our planning and scheduling framework hsts to reduce the complexity of science mission planning This work is part of an overall project to enable a small team of scientists to control the operations of a spacecraft The present process is highly labor intensive Users scientists and operators rely on a non codi ed un derstanding of the di erent spacecraft subs...
متن کاملResolution of direction of oceanic magnetic lineations by the sixth-generation lithospheric magnetic field model from CHAMP satellite magnetic measurements
[1] The CHAMP satellite continues to provide highly accurate magnetic field measurements from decreasing orbital altitudes (<350 km) at solar minimum conditions. Using the latest 4 years (2004–2007) of readings from the CHAMP fluxgate magnetometer, including an improved scalar data product, we have estimated the lithospheric magnetic field to spherical harmonic degree 120, corresponding to 333 ...
متن کاملGeological implications of continental magnetic anomalies derived from new CHAMP satellite data
A GIS based modelling technique has been developed to model the various geological units of the continents starting from the UNESCO geological map of the world. Depending upon the known rock types of the region, they are assigned a standard susceptibility value and using the Crust2.1 seismic crustal structure, a vertically integrated susceptibility (VIS) model is computed at each point of the r...
متن کاملSpatio-temporal characterization of the equatorial electrojet from CHAMP, Ørsted, and SAC-C satellite magnetic measurements
[1] The equatorial electrojet (EEJ) is an eastward electric current on the day-side, flowing in a narrow band along the dip equator in the ionospheric E region. Recent magnetic observations from the CHAMP, Ørsted, and SAC-C satellites, comprising more than 95,000 dip equator crossings from 1999 to 2006, have provided an unprecedented longitudinal coverage of the EEJ magnetic signature. We have ...
متن کاملEarth’s lithospheric magnetic field determined to spherical harmonic degree 90 from CHAMP satellite measurements
S U M M A R Y The CHAMP magnetic field mission is providing highly reliable measurements from which the global lithospheric magnetic field can be determined in unprecedented resolution and accuracy. Using almost 5 yr of data, we derive our fourth generation lithospheric field model termed MF4, which is expanded to spherical harmonic degree and order 90. After subtracting from the full magnetic ...
