[time-nuts] Timing Distribution in Mountainous Terrain

[Peter Monta]

Each pair of sites could maybe do two-way time transfer over VHF or
UHF meteor scatter.  I don't know what the achievable resolution might
be; I suppose it would depend on the size of the scattering entity
(plasma cloud) and its geometry relative to the two sites.  Sparse and
unpredictable measurement times shouldn't be a problem so long as
they're not too sparse.  Even if 30 ns were unachievable single shot,
averaging over multiple events would help given reasonable flywheel
oscillators (say rubidium).

The common-view UAV or mountaintop ideas would be simpler, though, if
they pass muster in other respects.  The mountaintop could also be
passive if that helps: pairs of antennas connected by a transmission
line and appropriately pointed.

Cheers,
Peter Monta
