Solar radiation and water vapor pressure to forecast chickenpox epidemics
European Journal of Clinical Microbiology & Infectious Diseases, 2014The clear seasonality of varicella infections in temperate regions suggests the influence of meteorologic conditions. However, there are very few data on this association. The aim of this study was to determine the seasonal pattern of varicella infections on the Mediterranean island of Mallorca (Spain), and its association with meteorologic conditions ...

Several aspects of solar radiation pressure
2006The disturbing influence of solar radiation pressure must be taken into account in modeling GPS orbits. The mathematical description of this disturbing force is complicated. There exist several models with distinct complexity. In the special case of GPS satellites there arise difficulties because of the irregular shape and surface of the satellites and

Noise in Pressure Transducer Readings Produced by Variations in Solar Radiation
Groundwater, 2004Variations in solar radiation can produce noise in readings from gauge pressure transducers when the transducer cable is exposed to direct sunlight. This noise is a result of insolation-induced heating and cooling of the air column in the vent tube of the transducer cable.

Solar Radiation Pressure: Exact Analysis
2012Moving beyond gravity-only dynamics about small bodies, we first consider the combined effect of solar radiation and solar tide perturbations on a spacecraft orbiting about an asteroid or comet. In this section we assume the central body can be modeled as a sphere, and neglect gravitational perturbations. This situation models orbital dynamics when far

Lunar Formation Control Using the Differential Solar Radiation Pressure
2019 27th Mediterranean Conference on Control and Automation (MED), 2019Using differential solar radiation pressure (DSRP) for formation keeping is not new. However, there is no design of a DSRP-based controller for lunar satellite formation keeping, where the C 22 sectorial harmonic and third-body effects are large, other than the J 2 zonal harmonic.

Deflection of the Local Interstellar Dust Flow by Solar Radiation Pressure
Science, 1999Interstellar dust grains intercepted by the dust detectors on the Ulysses and Galileo spacecrafts at heliocentric distances from 2 to 4 astronomical units show a deficit of grains with masses from 1 × 10 –17 to 3 × 10 –16 kilograms relative to grains intercepted outside 4 astronomical units ...

Hybrid Estimation of Solar Radiation Pressure for a Spinning Solar Sail Spacecraft
Journal of Spacecraft and Rockets, 2014Nomenclature A = reference area, m a1;2;3 = characteristic optical sail coefficients B = Lambertian coefficients FXSF = transverse component of the solar radiation pressure force acting on the sail, N FZSF = normal component of the solar radiation pressure force acting on the sail, N h = offset, m k1;2 = solar radiation pressure torque coefficients P =

A simplified Solar Radiation Pressure model for GNSS autonomous orbit prediction
2016 International Conference on Localization and GNSS (ICL-GNSS), 2016We present a two-parameter Solar Radiation Pressure model for GNSS autonomous orbit prediction, in which the parameters vary with the daily and seasonal variations in the angle between the Sun and the satellite's orbital plane. The estimator for this model's parameters is described.
