Lagrange Drifting Buoy (nooca SVP) ee la tuuri karo si loo eego Badweynta/ Dusha sare ee Badda Xogta salinity Heerkulka ee hadda oo leh Goobta GPS

Booska qulqulaya wuxuu raaci karaa lakabyo kala duwan oo qulqulaya hadda qoto dheer. Goobta GPS-ka ama Beidou, cabir mawjadaha badda adoo isticmaalaya mabda'a Lagrange, oo ilaali heerkulka dusha sare ee Badweynta. Dusha sare ee qulqulaya waxay taageertaa in meel fog la geeyo Iridium, si loo helo goobta iyo inta jeer ee gudbinta xogta.
