Dynamic gas-surface interaction modeling for satellite aerodynamic computations Drag coefficients are a large source of uncertainty when predicting the aerodynamic forces on orbiting satellites. Accordingly, the focus of this research is to improve the fidelity of drag modeling by investigating the nature of gas-surface interactions in low earth orbit. The author has investigated to what extent oxygen adsorption can influence the parameters of drag coefficient models, most notably the energy accommodation coefficient. Published by: Published on: |

The Ionospheric Mid-Latitude Summer Nighttime Anomaly This paper presents monthly variations of the mid-latitude summer nighttime anomaly (MSNA) of the ionosphere for the first time by using global observations of the FORMOSAT-3/COSMIC (F3/C), NASA TIMED-GUVI, ground-based radars and GPS receiver network. The MSNA is characterized by greater nighttime (19:00 LT - 24:00 LT, or period of larger solar zenith angles) ionospheric electron density than that during daytime (08:00 - 18:00 LT, or period of smaller solar zenith angles) at middle latitudes during solstices.

Gyroless-extending the TIMED mission The TIMED spacecraft is now it its eighth year of a two-year mission, amassing an unprecedented, uninterrupted collection of upper atmospheric data. Over the course of this time, degradation of the gyros has forced the need to allow operation without them. As a result, the attitude estimation algorithms have been enhanced to allow continued operation under gyroless conditions. This paper describes the algorithms implemented to perform attitude estimation with a tracker-only solution, as well as operational issues encountered ...

Use of two-line element data for thermosphere neutral density model calibration Traditional empirical thermospheric density models are widely used in orbit determination and prediction of low-Earth satellites. Unfortunately, these models often exhibit large density errors of up to around 30\% RMS. Density errors translate into orbit errors, adversely affecting applications such as re-entry operations, manoeuvre planning, collision avoidance and precise orbit determination for geodetic missions. The extensive database of two-line element (TLE) orbit data contains a wealth of information on satellite drag ...

Solar EUV irradiance variability derived from terrestrial far ultraviolet dayglow observations Remotely sensed ultraviolet emissions from the Earth s upper atmosphere are shown to mirror fluctuations in solar EUV irradiance during July 2002, including the overall increase and decrease as the Sun rotated, and episodic increases associated with multiple solar flares. The TIMED/GUVI dayglow observations are used to derive a new quantity, QEUVGUVI, which is a measure of integrated solar EUV electromagnetic energy shortward of 45 nm. Both the absolute QEUVGUVI values and their modulation by solar rotation agree well with t ...
