Bidirectional UWB Localization with Rigorous Sectoral Evaluations
… implementation process. The ability to combine two unique positioning perspectives (i.e., navigation and tracking) within a single scheme is, indeed, a paradigm shift in the way location-based services are observed in the literature. Much to the author's surprise, there are no well-documented …

Peer-to-peer wireless ultrawide-band localization of fast-moving entities
This thesis presents peer-to-peer localization techniques such that a group of mobile nodes can continuously track its topology, without relying on external infrastructure. Ultrawide-band (UWB) radios worn by each node (humans in our case) perform time-of-flight (TOF) measurements between different …

Radio frequency ranging for wireless sensor network localization
Wireless sensor networks (WSNs) have a diverse range of industrial, scientific and medical applications where the sensor nodes are of low cost, standard with respect to hardware architecture, processing abilities and communicate using low-power narrow-band radios. Position information of the …

Lunar Surface Navigation Using Gravity and Star Tracker Measurements
… bias in the lunar gravity field at various waypoints during a surface mission. As a test case, the reference position is determined using two-way ranging measurements between the ground system and the Lunar Pathfinder satellite. These measurements are processed through a combined weighted …
