- elfchief 7y agoNominally, yes, but the positioning error (according to the spec) is expected to be up to 425m after 14 days, growing worse over time until it hits a positioning error of ~10km at 180 days. (later generation satellites have an 'autonav' mode that presumably makes this less severe (by using SV-to-SV ranging and such so they're not completely blind to changes), but Galileo may not have that capability or there might not be enough SVs to use that capability yet)
