Hjälp! Vem tog min GPS?: Studie av redundanta metoder i integrerade positioneringssystem

Abstract [sv]

Möjligheten att bestämma sin position med ett par meters noggrannhet varhelst på jordklotetman befinner sig har med tillgången till GPS blivit möjligt för alla som investerar i en GPSmottagare,således även Försvarsmakten. GPS har dock begränsningar som gör att tillgångentill tjänsten kan blockeras med enkla medel av såväl systemets ägare som andra. I Försvarsmaktenfinns det anvisningar inför anskaffandet av satellitpositioneringssystem som gör gällandeatt detta endast skall utgöra ett komplement till andra redundanta metoder. För militäraändamål har GPS ofta integrerats tillsammans med tröghetsnavigering där de båda metodernakompletterar varandra. Utan tillgång till GPS kommer positionsfelet i ett sådant system efteren kortare tid växa sig stort. I följande studie görs en inventering av alternativa positioneringsmetodervilka utöver GPS kan integreras tillsammans med tröghetsnavigering. Studienvisar att det finns metoder vilka antas kunna integreras i ett positioneringssystem samtidigtsom noggrannheten bibehålls.

Abstract [en]

The ability to determine one’s position with a couple of meters accuracy anywhere on earthhas become possible for all who invest in a GPS receiver, even the Swedish Armed Forces.However GPS has limitations that make it possible to deny access to the service by simplemeans from the owner of the system as well as of others. There are regulations within theSwedish Armed Forces for the procurement of satellite positioning systems that states theseshall be considered as complement to other, redundant methods. For military purposes GPS isoften integrated with an inertial positioning system where the two methods complement eachother. Without access to GPS in such a system the error growth is unlimited also within alimited period of time. The following study makes a survey of complementary methods thatbesides GPS is possible to integrate together with inertial navigation. The work indicates thatthere are methods which are assumed to use in an integrated positioning system with retainedaccuracy.
