I get it.

Why this baffled me is because I can accurately track my location on flights at 10,000+ feet with no data.
From time to time I would compare my location on Google Maps with my location on the plane's InFlight Tracker.

Cell phones typically use a form of GPS called Assisted GPS. That requires cell phone tower data for the your initial coarse location. There are no cell towers that accept data at sea.  You may also notice your cell phone clock will go wacky since it too gets it's time sync from cell towers. A reason why people recommend a wrist watch while cruising.

Thanks for the info.
My phone's time was ok, even with the DST going forward an hour during the cruise.

I'm just hung up on why that specific location (Grand Bahama Shipyard) for 4.5 days. I imagine it would have placed me at random places on the globe.
Maybe Royal Caribbean has some type of communications tower there. 🤔

Hello guys.
I just completed my first cruise & I noticed that after about 2-3 hours from leaving Miami, my Google Maps location said I was at the Grand Bahama Shipyard in Freeport, Bahamas.
I knew that was incorrect but paid it no mind until the next day when we arrived at Nassau, Bahamas, but the GPS stated that we were at Freeport.
During this time I had my Samsung device on Airplane Mode, but WiFi, Bluetooth, Location & Sync enabled, and I was connected to the Ship's VOOM Surf & Stream data service.
The only time my location was updated was when I got off the ship in Nassau, Bahamas, and in Montego Bay Jamaica & disconnected from VOOM & far away from the ship. But as soon as I reconnected to the WiFi, my position moved back to Grand Bahama Shipyard in Freeport, Bahamas.

Might I also add that I opened the Maps app on my MacBook and it showed the same
My Cabin-mate tried the same on their iPhone and maps would not load
All devices were connected to the Ships VOOM WiFi service.

From my understanding, GPS doesn't really need a data service to give your location, as long as the device has an unobstructed view of 2 or more satellites. The data is used to download the map to display to the user.
I wanted to have my first cruise documented in my Maps Timeline.

Any Idea why this is so?
