Cosmic GPS ionospheric sensing and space weather
As our civilization becomes more dependent on space based technologies, we become more vulnerable to conditions in space weather. Accurate space weather specification and forecasting require proper modeling which account for the coupling between the sun, the magnetosphere, the thermosphere, the ionosphere and the mesosphere.
Impact of Eccentricity on East-West Stationkeeping for the GPS Class of Orbits
The investigation will reveal that the influence of luni-solar perturbations contributes to the growth of eccentricity, thus increasing the probability of encountering chaotic motion during a typical satgellite lifetime.
Impact of Eccentricity on East-West Stationkeeping for the GPS Class of Orbits
A strong relationship exists between eccentricity and the potential for an orbit with a mean motion commensurability to the Earth's rotation rate to be chaotic.
