[LONDON] The perils of the new Arctic shipping route, warmed by climate change, may diminish with a British-Russian radio navigation initiative, being developed to shore up vulnerable satellite-based alternatives.

The UK system, on trial in the hectic shipping lanes past Dover and drawing interest from South Korea - after the North jammed satellite systems - may tie up with parallel work underway in Russia, developers say.

The Arctic route still faces high risks from extreme weather and icebergs.Vessels increasingly rely on systems that employ satellite signals to find a location or keep exact time, including the Global Positioning System (GPS).
