Development of a Mission Design Tool for Computing Libration Point Formations Using Differential Corrections Initialized with a Genetic Algorithm
<p>"The growing interest in deep space spacecraft missions and distributed spacecraft formations has established the need for state-of-the-art advancements in the areas of relative dynamics and mission design. The focus of this research is to develop methods for identifying natural (i.e. ballistic) …

Relative Accuracy and Precision of Differentially Corrected GPS on a Moving Vehicle
Differential corrections provide a method to improve the real-time accuracy and precision of GPS, but there are several sources of differential corrections and each have an associated accuracy and precision. In dynamic applications, the speed and heading of the rover may also have an effect on the …

Orbit determination for medium altitude eccentric orbits using GPS measurements
… determination process was performed using the differential corrections function of GTDS. The determined orbit was compared to the orbits used in the production of the simulated navigation solutions. The results of this comparison implied that the orbits could be reproduced from GPS navigation …

A Localization Solution for an Autonomous Vehicle in an Urban Environment
… dead reckoning or an off-the-shelf GPS with differential corrections. However, as the surroundings become more complex, so does the localization problem. The urban environment is a prime example of a situation in which a vehicle's surroundings complicate the problem of position estimation. …
