The dispersion of the measurement of electromagnetic disturbance above 1 GHz is mainly affected by site imperfections (expressed by SVSWR). To evaluate the uncertainty in electromagnetic disturbance measurements at 1 18 GHz, we measured SVSWR and the field strength at 9 measurement site. From our result, the measured field strength at each measurement site was observed in the range of 2σ that d...

Magnetism dominates the structure and dynamics of the solar corona. Current theories suggest that it may also be responsible for coronal heating. Despite the importance of the magnetic field in the physics of the corona and despite the tremendous progress made recently in the remote sensing of solar magnetic fields, reliable measurements of the coronal magnetic field strength and orientation do...

The real-time accurate measurement of the geomagnetic-field is the foundation to achieving high-precision geomagnetic navigation. The existing geomagnetic-field measurement models are essentially simplified models that cannot accurately describe the sources of measurement error. This paper, on the basis of systematically analyzing the source of geomagnetic-field measurement error, built a compl...
