This paper detailedly introduces the application of geomagnetic vector survey in civil aviation by two project cases.

Two-segment information fusion attitude determination method for spacecraft from vector observations;

Summary of algorithms for determination of spacecraft attitude from vector observations;

Determination of satellite orbital attitude from vector observation:Euler-angle estimator;

In this thesis, some discussion on the automatic measurement via space geometrical relationship and observed vectors and adjustment kinetic model of position and attitude would be carried out.

The Beijing standard seismic station in the seismological and geomagnetic observation normalization;

In order to study tectonomagnetic effect of Zijinguan active fault,an observation network with 9 survey lines,528 sites and 6 temporary stations is estblished in Tumu Shihe area in Huailai,and precise geomagnetic observations are carried out.

The geomagnetic observations are carried out in Beijing area for earthquake prediction study and the encouraging progress has been made in research of seismomagnetic precursor and earthquake prediction test.

For the require of adaption and fault-tolerance of the full system,it is proposed that measurement-vector fusion algorithm added with fuzzy controller be taken in the integrated navigation system.
