[Giorgis]

Is it possible to measure distance, even behind walls to a few cm
accuracey over 50m ?

If you want to go through walls, how did you intend to define the endpoint for
your distance measurement? Are you thinking between, e.g., a transmitter and
receiver that might be on opposite sides of a wall?

Yes lets say I would like to mwasure the distance between the corners
of my house with no line of sight. Only with two devices at either end.

Is it possible

Thanks

Possibly, with DGPS. It depends on how clear a view of the sky you have.

Theoretically radar at the right frequencies could do what you want. You
might want to look at Ground Penetrating Radar, which does something
similar and is in use in the 'real world'. If you want to do it without
a big (military, corporate, research...) budget I think you're out of
luck.

A dgps unit with distance travelled between
waypoints.

Yes, for very large amounts of money.

Why not just pick a third point, visible from both A and B, call it C,
and just trig it out?

C

/ _____ \
/ [ ] \
A [HOUSE] B
[_____]

Measure the distances AC and AB, and the angle ACB, and it should be just
arithmetic from there.

Good Luck!
