GPS, Pseudolites (PL) and Inertial Navigation Systems (INS) exhibit complementary performance characteristics, advantage of which can be taken through integration. System integration can be made at different levels, namely loose coupling, tight coupling and ultra-tight coupling, depending on the desired robustness (vs complexity) of the of the overall system design. In ultra-tight integration, ...

This research aims at enhancing the accuracy of land vehicular navigation systems by integrating GPS and Micro-Electro-Mechanical-System (MEMS) based inertial measurement units (IMU). This comprises improving the MEMS-based inertial output signals as well as investigating the limitations of a conventional Kalman Filtering (KF) solution for MEMS-IMU/GPS integration. These limitations are due to ...

Having studied the structure and properties of inertial-modes in a neutrally buoyant, uniformly rotating sphere (Wu 2004), we examine here their effect on tidal dissipation in Jupiter. The rate of tidal dissipation caused by resonantly excited inertial-modes depends on the following three parameters: how well coupled inertial-modesare to the tidal potential, how strongly dissipated inertial-mod...

Magnetohydrodynamic (MHD) turbulence in the solar wind is observed to show the spectral behavior of classical Kolmogorov fluid turbulence over an inertial subrange and departures from this at short wavelengths, where energy should be dissipated. Here we present the first measurements of the electric field fluctuation spectrum over the inertial and dissipative wavenumber ranges in a β & 1 plasma...

Task dynamics corresponding to rhythmic movements emerge from interactions among dynamical resources composed of the musculature, the link segments, and the nervous and circulatory systems. This article investigated whether perturbations of interlimb coordination might be effect over circulatory and nervous elements. Stiffness of wrist-pendulums oscillated at a common tempo and at 180 degrees r...

Static pressure fluctuations measured in the atmospheric surface layer over a grass covered forest clearing are studied in the context of Townsend’s 1961 hypothesis regarding the effect of the outer region on the inner region. It is shown that large-scale pressure features are actively straining the inertial-scale pressure fluctuations, thus invalidating the direct extension of Kolmogorov’s 194...

Magnetohydrodynamic (MHD) turbulence in the solar wind is observed to show the spectral behavior of classical Kolmogorov fluid turbulence over an inertial subrange and departures from this at short wavelengths, where energy should be dissipated. Here we present the first measurements of the electric field fluctuation spectrum over the inertial and dissipative wave number ranges in a Beta > or a...
