Why "a pair of light houses" ? Do they only come in couples ?

TWO LIGHTHOUSES DEFINE THE TERRITORIAL SEA OF CHINA'S SOUTH CHINA SEA ISLANDS.

If you know the distance between two lighthouses, and you can determine the angle formed between the line of sight observations of the lighthouses and the line from the ship to the closest point on the shore, armed with these three values, you can calculate the distance between your ship and nearest point on the shore.  For that matter, you can pick any point on the shore, as a matter of fact, measure the above angles between your line of sight to that point and the light of sight to each lighthouse, and you can compute your distance to that point on the shore, using the Law of Sines.

To any navigator, therefore, there will be no excuse for entering China's 12-mile-radius of territorial sea measured from its shoreline, entry into which would be considered intentional, and if not explainable by necessity or emergent reasons, would therefore constitute an act of aggression on a peaceful country, justifying a defensive reaction from the country so attacked.

In short, you cannot blame your faulty GPS if you intrude into China's sovereign territorial sea.  With two lighthouses, you should have known.

Is China providing all ships with new charts to include the extra bits they are building in the SCS?

Do ships not have radar?

What do these artificial islands do for China? In perhaps a century from now, they will be submerged ...

Not is they pile all the BS on them to keep the height up

CHINA'S ACTION SPEAKS LOUDER THAN WORDS - WELCOME TO THE SOUTH CHINA SEA!!!

Who needs GPS to sail ...

GPS is useless in overcast cloudy conditions, my satnav in my car works when it is cloudy, foggy, rainy and worse, surely those on ships are better than the one I bought for 500 RMB on TaoBao

"the angle formed between the line of sight"

But how can you see these distant lighthouses on such a dark and stormy night when you claim that satnav is not practicable ? Lighthouses around the world are built many miles apart yet you propose China sets up this "couples /pairs" system which would require that they be relatively close together in order for the navigation calculations to be made. How many sovereign "islands" and how many of such lighthouses would need to be built in order for this system to operate ?
