Cosmic ray muons provide a viable replacement for GPS for 3D positioning on Earth and underwater

the verdict

Recorded sources
5 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Multiple studies demonstrate that cosmic-ray muon positioning and navigation systems (such as muPS and MuWNS) provide a viable 3D positioning alternative in environments like underground, indoor, and underwater where GPS signals cannot reach.

The analysis

All retrieved papers support the premise that cosmic ray muons can be used for positioning and navigation in environments where GPS fails, such as underground and underwater, with increasing accuracy over recent developments.
