Apparently the units are getting so good at picking up sat signals that they are picking up very low quality signals that are introducing error.

The T-AO touched bottom, gashed one of her tanks and subsequently spilled a large quantity of DFM in Sasebo Wan. JMSDF went out later and resurveyed the channel. It turned out the islet was actually the above water portion of an entire underwater ridge between two islands that wasn't on the chart. And Sasebo has been a major naval and commercial port since the late 19th century.
