Resumen

In the United States, smartphone ownership surpassed 69.5 million in February 2011 with a large portion of those users (20%) downloading applications (apps) that enhance the usability of a device by adding additional functionality. a large percentage of apps are written specifically to utilize the geographical position of a mobile device. One of the prime factors in developing location prediction models is the use of historical data to train such a model. with larger sets of training data, prediction algorithms become more accurate; however, the use of historical data can quickly become a down

Resumen

The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning. An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS rel

Resumen

Proximity Warning Systems are currently the focus of many research groups. Their goal is to produce a system that will reduce the number of run over incidents that occur in large mobile equipment operations. A majority of these incidents occur when the equipment starts from the In-rest state and begins to move. The addition of a transmission locking mechanism to a GPS based proximity warning system will prevent more run over incidents. This transmission locking mechanism will automatically prevent equipment from moving when there is a high risk for a potential run over incident to occur.

Navigation can be described as the art of finding the way from one location to another. Clearly navigation is something that we perform in our every day lives and the role of navigation can not be underestimated.

This paper is the result of a masters thesis performed at Linköping University for Saab Bofors Dynamics in Linköping, Sweden. Attitude is defined as the orientation of a coordinate frame in reference to another coordinate frame. This is often referred to as three consecutive rotations, called roll, pitch and yaw (or heading). Attitude determination is generally performed using inertial navigation systems composed of gyros and accelerometers. These systems are highly accurate but are very expensive and experience a drift when used for a long period of time. The global positioning system, or GPS

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California<br>In the last few years there has been a proliferation of GPS receivers and receiver manufacturers. Couple this with a growing number of DoD test programs requiring high accuracy Time-Space-Position-Information (TSPI) with diminishing test support funds and/or needing a wide area, low altitude or surface tracking capability. The Air Force Development Test Center (AFDTC) recognized the growing requirements for using GPS in test programs and the need for

Resumen

Micro aerial vehicles and other autonomous systems have the potential to truly transform life as we know it, however much of the potential of autonomous systems remains unrealized because reliable navigation is still an unsolved problem with significant challenges. This dissertation presents solutions to many aspects of autonomous navigation. First, it presents ROSflight, a software and hardware architure that allows for rapid prototyping and experimentation of autonomy algorithms on MAVs with lightweight, efficient flight control. Next, this dissertation presents improvments to the state-of-t

Resumen

This thesis examines the effect on height determination of the antenna phase centre variation of GPS user segment antennae. A discussion of the various antenna types in common use is followed by an explanation of the problem at hand. In particular the effect of the antenna's environment on the phase centre variation is covered more fully, since the phase variation phenomenon itself is largely unexplained in the engineering community to date. A number of examples of the heighting errors caused by this phenomenon are presented, followed by specifically designed experiments, which quantify the ef

Resumen

Eftersom att både GNSS GPS och GLONASS har många likheter så finns möjlighet att utnyttja systemen i kombination. Dock föreligger olikheter vilket gör att systemen inte är fullkomlig kompatibla med varandra. Diskrepans i koordinater och tidsram utgör ett stort hinder för att kombinera dessa system. Men lösningar för koordinatstransformering har tagits fram för att eliminera dessa divergenser (Roßbach, 2001) BeiDou GNSS system till skillnad från GNSS GPS/GLONASS är ett av det senaste etablerade navigationssystem, vilket ställer frågor för användare om systemets kvalitéer och brister.
