Position of A-ROSA ALVA
We currently have no AIS position for A-ROSA ALVA (A-ROSA). As soon as a receiving station picks it up again, the position will appear here automatically.
The usual reasons for a gap: the ship is on the open sea out of range, in dry dock, or simply not transmitting right now.
Questions about the position of A-ROSA ALVA
How current is the position of A-ROSA ALVA? +
AIS reports reach us around the clock; a fresh position is usually only a few minutes old. If it says “6 hours ago” above, the ship has not reached a receiving station since. The page always shows the most recent report we have and tells you how old it is.
Why is the position sometimes missing? +
AIS is line-of-sight radio. The stations stand on the coast and hear about 50 to 100 kilometres out. A ship in the middle of the Atlantic or the Pacific is invisible to them and only reappears as it approaches the next coast. Then there are yard periods when the transmitter is switched off. Neither is a cause for concern.
Where does the data come from? +
From AIS, the Automatic Identification System. Ships of this size must carry it. It transmits position, course, speed and destination by radio; receiving stations ashore pass the reports on. We match them to A-ROSA ALVA via its MMSI and IMO numbers and record the positions, which is also where the sailed route comes from. IMO: 9902158.
