Steady State Results for the X, Y, Z Kalman Tracking Filter

An X, Y, Z Kalman tracking filter is described and its steady state characteristics are analytically determined when the radar sensor meaures range, bearing, and elevation (?, ?, ?) at uniform intervals of time, T seconds. The relationship between the quantities measured by the sensor (?, ?,?) and the Cartesian coordinate system (X, Y, Z) is explicitly considered.     

Modularity,reconfigurability, and autonomy for the future in spacecraft: A review

The shape of a spacecraft is transitioning from monolithic, manual, and static to modular, autonomous, and dynamic. Modular Reconfigurable Spacecrafts (MRSs) offer better solutions than traditional monolithic spacecrafts in several aspects, and may become the next generation of spacecraft systems with efficient design, fast deployment, flexible application, and convenient management. This paper reviews the development and technology of MRS from three aspects: Modularity, reconfigurability, and autonomy. Despite the progress of research on MRS, there is still a lack of unified standards and little understanding of related concepts. Based on the understanding of basic concepts, the studies conducted on MRS are reviewed to identify technical requirements and solutions. Aiming at the future development trend of MRS, a novel modular self-reconfigurable spacecraft, referred to as MagicSat, is proposed. Furthermore, the MagicSat system composition, advantages, and application prospects are studied. The enabling technologies and major challenges of MRS are further analyzed in terms of modularization, integrated management, and self-reconfiguration technologies. Finally, the future development trend of MRS technology is predicted, and corresponding suggestions are provided.

Analytical Results for the x, y Kalman Tracking Filter

A two-dimensional x, y Kalman tracking filter is analyzed for a track-while-scan (TWS) operation when the radar sensor measures range and bearing (r, ?) at uniform sampling intervals T seconds apart. This development explicitly considers the coupling between the quantities measured by the sensor (r, ?) and the Cartesian x, y coordinate system selected for the tracking operation. The steadystate components of the gain and error covariance matrixes are analytically determined under the assumption of a white noise maneuver acceleration model in two dimensions. These results are verified by computer calculation of the Kalman filter matrix equations.

SWE,a comprehensive plasma instrument for the WIND spacecraft

The Solar Wind Experiment (SWE) on the WIND spacecraft is a comprehensive, integrated set of sensors which is designed to investigate outstanding problems in solar wind physics. It consists of two Faraday cup (FC) sensors; a vector electron and ion spectrometer (VEIS); a strahl sensor, which is especially configured to study the electron strahl close to the magnetic field direction; and an on-board calibration system. The energy/charge range of the Faraday cups is 150 V to 8 kV, and that of the VEIS is 7 V to 24.8 kV. The time resolution depends on the operational mode used, but can be of the order of a few seconds for 3-D measurements. Key parameters which broadly characterize the solar wind positive ion velocity distribution function will be made available rapidly from the GGS Central Data Handling Facility.

The gravitational potential for a moving observer, the perihelionshift of Mercury, and photon deflection

Acceptance of Einstein's second postulate, combined with the Principle of Equivalence, requires the introduction of space-time curvature in the presence of massive objects. In this paper, it has been demonstrated that the radiation continuum model (RCM) of light results in a modification to Newton's static gravitational potential. Applying this modified potential to the case of Mercury's anomalous perihelion advance accounts for the entire 43" per century, and provides a form equivalent to that of GRT. Thus, this model will work equally well for any system to which it is applied, all without resorting to the space-time curvature of GRT. The same potential, applied to the problem of a solar grazing photon, gives a solution identical in form and content to that of GRT as well. Such results lead to the conclusion that these effects are not attributable to massive objects curving space-time     

Helium, Oxygen, Proton, and Electron (HOPE) Mass Spectrometer for the Radiation Belt Storm Probes Mission

The HOPE mass spectrometer of the Radiation Belt Storm Probes (RBSP) mission (renamed the Van Allen Probes) is designed to measure the in situ plasma ion and electron fluxes over 4π sr at each RBSP spacecraft within the terrestrial radiation belts. The scientific goal is to understand the underlying physical processes that govern the radiation belt structure and dynamics. Spectral measurements for both ions and electrons are acquired over 1 eV to 50 keV in 36 log-spaced steps at an energy resolution ΔE _FWHM/E≈15 %. The dominant ion species (H⁺, He⁺, and O⁺) of the magnetosphere are identified using foil-based time-of-flight (TOF) mass spectrometry with channel electron multiplier (CEM) detectors. Angular measurements are derived using five polar pixels coplanar with the spacecraft spin axis, and up to 16 azimuthal bins are acquired for each polar pixel over time as the spacecraft spins. Ion and electron measurements are acquired on alternate spacecraft spins. HOPE incorporates several new methods to minimize and monitor the background induced by penetrating particles in the harsh environment of the radiation belts. The absolute efficiencies of detection are continuously monitored, enabling precise, quantitative measurements of electron and ion fluxes and ion species abundances throughout the mission. We describe the engineering approaches for plasma measurements in the radiation belts and present summaries of HOPE measurement strategy and performance.
