This thesis studies algorithms to estimate an aircraft’s position with different information from various radio stations. Because aircrafts both civilian and military are heavily dependant on GNSS signals, it can be interfered from hostile sources. The aircraft shall then be able to navigate without the GNSS signals. This thesis focuses on three radio navigation systems, DME,VOR and TACAN. With the measurements from these three radio stations and measurements from the inertial navigation system one can estimate a position with an estimation filter.

Abstract:
In the case of one car following another to a destination, it is very effective at getting the second vehicle to the destination quickly; however, the driver of the second car may not learn the route. Yet, for individuals, such as firefighters, law enforcement, and military personnel, it is imperative that a route be learned quickly and accurately and that an awareness of the situation is maintained while they traverse the given route. This leads to three questions, (a) will navigation aids affect initial route navigation; (b) will navigation aids affect retention; and (c) will navigation aids

Abstract:
Le thème central de la thèse concerne l’utilisation des données de radio tracking pour le développement d’éphémérides planétaires, en particulier, dans deux cas : 1) analyse de données de navigation de la mission Cassini pour améliorer les éphémérides de Saturne et augmenter notre connaissance du système solaire externe ; 2) simulation des données radio de la mission ESA BepiColombo collectées durant la phase orbital à Mercure, pour évaluer leur contribution sur le développement des éphémérides planétaire de l’Intégrateur Numérique Planétaire de l’Observatoire de Paris (INPOP).Le premier sujet

Abstract:
Reliable and accurate positioning systems are expected to significantly improve the safety for first responders and enhance their operational efficiency. To be effective, a first responder positioning systemmust provide room level accuracy during extended time periods of indoor operation. This thesis presents a system which combines a zero-velocity-update (ZUPT) aided inertial navigation system (INS), using a foot-mounted inertial measurement unit (IMU), with the use of opportunistic multi-frequency received signal strength (RSS) measurements. The system does not rely on maps or pre-collected
