Can GPS send message?
As befits a GPS device, it’s all done with satellites. Delorme’s InReach GPS Communicator lets you send text messages, even when you are in the wilderness and far away from cellphone coverage. As befits a GPS device, it’s all done with satellites.
How accurate is mobile GPS?
For example, GPS-enabled smartphones are typically accurate to within a 4.9 m (16 ft.) High-end users boost GPS accuracy with dual-frequency receivers and/or augmentation systems. These can enable real-time positioning within a few centimeters, and long-term measurements at the millimeter level.
Are there cell towers in the ocean?
The main reason there is no cell coverage on the seas it due to how the system is designed. A tower lies in the middle of a cell with multiple antennas and all the equipment needed to transmit calls or data. Cell towers are only designed to cover a small area, and they are all placed on land.
Is there GPS over the ocean?
The global positioning system (GPS) is commonly used on land and in the air to obtain position and timing information. However, the radio frequencies used by GPS cannot penetrate in seawater, requiring a different system for underwater positioning.

How accurate is the GPS on your phone?
If you’re outside and can see the open sky, the GPS accuracy from your phone is about five meters, and that’s been constant for a while. But with raw GNSS measurements from the phones, this can now improve, and with changes in satellite and receiver hardware, the improvements can be dramatic.
