A quality assessment of the GNSS systems Galileo and BeiDou [PDF]
, 2019 Denne oppgaven gir et innblikk i de to nye GNSS-systemene, Galileo og BeiDou, som i undersøkelsesperioden ikke var fullt operative. Vi skal se at de er bygd opp noe ulikt i forhold til det vi allerede kjenner til, GPS og GLONASS.
