In an unmanned aircraft vehicle, a navigation system is needed to calculate its orientation and translation. The can utilize data from the accelerometer, gyroscope, magnetometer, GPS. be precisely calculated accelerometer magnetometer when sensor in static state. Meanwhile, under dynamic conditions, more gyroscope data. order obtain robust system, fusion based on Kalman filter built magnetomete...

Optically pumped helium magnetometers are important instruments whichhave many applications in military, mass spectroscopy and space applications. In thispaper, the working principles of helium magnetometers have been explained. There isalso an introduction of a new method for finding the resonant frequency, which hasadvantages to the typical method such as more sample r...

Based on an estimated solar wind condition around 1–2 September 1859, we were able to reproduce the Carrington magnetic storm magnetometer record, with the H-component depression of 1600 nT, made at Colaba Observatory in Mumbai, India. We used an updated Dst prediction model from Temerin and Li (2002), which provides a prediction efficiency of 0.91 for 1995– 2002 interval using a fixed set of m...

A magnetometer-based filter and smoother are presented for estimating attitude, rate, and boom orientations for a spinning spacecraft that has wire booms. These estimates are needed to analyze science data from the subpayloads of a recent sounding rocket mission. The estimator is initialized with the measured angular rate of each subpayload at ejection and thereafter relies solely on three-axis...
