1. 21. Aiding Navigation for Groups of Aircraft with Bearing and Distance Measurements

   University essay from Linköpings universitet/Reglerteknik

   Author : Mattias Olsson; [2018]
   Keywords : Navigational enhancing; consensus filtering;

   Abstract : This thesis extends previous work on navigational aidingof groups of aircraft, primarily intended for the fighter SAAB JAS 39 Gripen,as long as an aircraft gets GPS signals, it is easy to estimate position, but theGPS is relatively easy to jam, rendering alternative methods of positioning necessary.To use internal sensors measuring accelerations and angular velocities is agood replacement on short terms, but gives a drift in positioning over longer timeperiods.

4. 23. 5G Positioning using Machine Learning

   University essay from Linköpings universitet/Reglerteknik

   Author : Magnus Malmström; [2018]
   Keywords : 5G; Positioning; Non Line of Sight NLOS ; Urban Canyons; Machine Learning; Neural Networks; Random Forest; Detection; Neyman-Person; Generalized Likelihood Ratio Test; Kalam Filter;

   Abstract : Positioning is recognized as an important feature of fifth generation (\abbrFiveG) cellular networks due to the massive number of commercial use cases that would benefit from access to position information. Radio based positioning has always been a challenging task in urban canyons where buildings block and reflect the radio signal, causing multipath propagation and non-line-of-sight (NLOS) signal conditions.
