Abstract We present the construction of a two-state model atomic gravimeter and associated Kalman recursion to estimate gravity acceleration from an gravimeter. It is found that estimator greatly improves estimation precision in short term by removing white phase noise. The residual noise estimates follows for more than $100\ \text{s}$ highlig...

Scientists have, within the frame of the Conference on Disarmament, been successfully engaged in support of the Comprehensive Nuclear Test Ban Treaty (CTBT) for many decades, starting long before negotiations began. This article proposes an International Scientific Network (ISN) to engage the global scientific community to explore how scientific and technological developments can support nuclea...

The Education Ambassadors program was established in 2008 by the International Society of Nephrology (ISN). To push new projects, skills, or services, community-based research, screening programs, Renal centers throughout world can submit an application to Educational (EA) Program receive professional assistance and hands-on training. ISN ambassadors provide guidance on clinical cases studies p...

An experiment comparing the location accuracy of gravity matching-aided navigation in the ocean and simulation is very important to evaluate the feasibility and the performance of an INS/gravity-integrated navigation system (IGNS) in underwater navigation. Based on a 1' × 1' marine gravity anomaly reference map and multi-model adaptive Kalman filtering algorithm, a matching location experiment ...

In atom interferometers based on two photon transitions, the delay induced by the difference of the laser beams paths makes the interferometer sensitive to the fluctuations of the frequency of the lasers. We first study, in the general case, how the laser frequency noise affects the performance of the interferometer measurement. Our calculations are compared with the measurements performed on o...

In order to improve the accuracy of repeat gravity surveys for reservoir monitoring, it is desirable to perform continuous gravity measurements in addition to the ordinary survey program. We can apply time series analysis to the continuous recording to evaluate the causes of various gravity variations. We have made continuous gravity measurements using a Scintrex CG-3M gravimeter at several geo...
