Current Research
Bright fireballs that pass through the atmosphere, under the right conditions, can result in a meteorite falling to Earth. When observed from multiple locations, the atmospheric trajectory and orbit of the meteoroid can be determined. I work as part of the Australian Desert Fireball Network project and look at different methods of meteoroid trajectory analysis. These include extended Kalman filters, interactive multiple models (to investigate fragmentation modelling) and bootstrap particle filters (as this provides the ability to explore a larger range of poorly constrained trajectory parameters). The results aim to improve search area predictions for meteorite recoveries identified by fireball networks.
