Abstract [en]

Real-time asset tracking can be used to increase personnel safety, security and workflow in

different types of facility’s or assembly lines. There is many ways this can be done but one way

is by using an Ultra Wide-band sensor network. This thesis describes a specific part of such a

system. The task was to construct and evaluate the server software that will handle incoming

data from the sensor network, but also how it uses the data to calculate the position of the

tracked asset. The goal was to create an efficient and flexible server application that can

handle multiple assets that uses an accurate positioning algorithm. The result showed with the

best recorded configuration that towards the middle of the test area the accuracy measured

was nine centimeters. With the maximum amount of positions that the test server could

handle was 6000 positions per second. The conclusions about this thesis are that the

positioning application is promising because of its accuracy, its dynamic ability’s and its


Abstract [sv]

Positioneringsalgoritm och positioneringsserver till ett positioneringssystem

Möjligheten att spåra tillgångar kan användas för att öka personalens säkerhet, minska

stöldrisker och förbättra arbetsflödet. Ett sätt att göra detta på är genom att använda sig av ett

sensornätverk som i sin tur kommunicerar med Ultra Wide-band. Den här rapporten beskriver

en del av ett sådant system. Uppgiften var att konstruera och utvärdera en servermjukvara

som kan hantera data från ett sådant sensornätverk men som också kan beräkna positionen av

de spårade tillgångarna. Målet var att applikationen skulle vara flexibel, kunna spåra många

tillgångar samtidigt och bestämma dess position med hög noggrannhet. Resultatet visade att

mot mitten av testområdet var noggrannheten nio centimeter. Samt att testservern kunde

hantera 6000 positioner per sekund. Slutsatsen var att positioneringsapplikationen är lovande

tack vare dess positionsnoggrannhet, dynamiska konfigurationsmöjlighet och prestanda.
