Question 1

Where is JUPITER right now?

Accepted Answer

JUPITER has not broadcast an AIS position for 3 days. The most recent broadcast placed it in the Gulf of Mexico, on 5 Sep 2026, 21:31 UTC. It was sailing from PALM BEACH to CLASS B. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

Question 2

What are the identifiers for JUPITER?

Accepted Answer

JUPITER broadcasts MMSI 983191089. The MMSI is the radio identifier used by AIS; the IMO number stays with the ship for life and does not change with re-flagging or sale.

Question 3

What type of ship is JUPITER?

Accepted Answer

JUPITER is classified as a pleasure craft vessel. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full pleasure craft fleet at /vessel-type/yacht.

Question 4

Tap "View on map" to centre the live tracker on the vessel and watch its movement update in real time. The same data is available offline-friendly in the iOS and Android apps.

Question 5

How often is JUPITER's position updated?

Accepted Answer

AIS transponders broadcast position every 2 seconds when underway at high speed and up to every 3 minutes at anchor. The position you see refreshes whenever the ship is in range of a coastal AIS receiver or a satellite pass — typically seconds in coastal waters and minutes offshore.

Question 6

What class is JUPITER?

Accepted Answer

As a pleasure craft, JUPITER sits in the same design class as the other pleasure crafts listed in the Similar Vessels section of the vessel page, or in the full pleasure craft directory at /vessel-type/yacht.
