and the using of Michelson Interferometer Element as a substitution of narrow Lyot-element was proved to be very successful from GONG on the ground (Global Oscillation Network Group) to the space missions of MDI/SOHO (Michelson Doppler Imager, the Solar & Heliospheric Observatory15) and HMI/SDO...
Lee’s research at York to develop a series of space technologies that will lead to scientific nanosatellite missions in the near future. Currently, she is investigating several areas including micro-spectrometer design, micro-propulsion system, MEMS based attitude sensors and actuators and algorithms ...
Reconstruction of dynamical parameters is one of the main challenges faced in the on-orbit servicing missions for defunct spacecraft. And the quaternion plays a major role in parameterizations of the dynamical model. In this paper, the analytical solution of the quaternion differential equations of ...
Tidal data monitoring is an important component for onshore and offshore activities. This study designs a low-cost tide gauge and an architecture that comb
Multiple-Step Randomly Delayed Adaptive Robust Filter With Application to INS/VNS Integrated Navigation on Asteroid Missions. IEEE Access 2020, 8, 118853–118868. [Google Scholar] [CrossRef] Qin, W.; Wang, X.; Bai, Y.; Cui, N. Arbitrary-step randomly delayed robust filter with application ...
Numerous future missions will entail landing operations to deploy technological systems on the surface of the Moon. The driving precision landing requirement for the autonomous landing is to land within ∼100 m of a predetermined location on the lunar surface, or any other planetary surface [9]....
In large budget missions, expensive sensors like star trackers or gyroscopes are used, being easily integrated in a Kalman filter framework. However, there is a growing interest in low-cost missions with other types of sensors having moderate cost, low weight and small size. The integration of ...
Real-time precise orbit determination (POD) of low earth orbiters (LEOs) is crucial for orbit maintenance as well as autonomous operation for space missions. The Global Positioning System (GPS) has become the dominant technique for real-time precise orbit determination (POD) of LEOs. However, ...
A low-insert loss and high-return loss bandpass filter based on cut-off rectangular waveguide for satellite communication application. Int. J. RF Microw. Comput.-Aided Eng. 2020, 31, e22351. [Google Scholar] [CrossRef] Zhang, F.; Xu, L.; Zhang, J.; Nan, P.; Jin, X.; Pan, G....
Otherwise, there have been studies that represented the stable TAN performance to make a detour around the flat and repetitive terrains through path planning or simultaneous localization and mapping (SLAM) techniques [12,13], but as vehicles have been recently required to perform various missions, ...
