Galactic Drifter SETI - description

Summary of the "Galactic Drifter SETI" search strategy:

This strategy is not intended to replace others currently under
consideration and in practice, but does offer an attractive economy of
effort to the Earth-side of the search, given its tight constraints in
look direction and time.

This strategy assumes the existence of automated stations in
counter-revolving galactic orbits. Such orbits are useful to survey,
monitor and revisit in situ large numbers of galactic targets,
including potential sites of intelligent life.

Communication between drifters and other sites in the presumed network
can be greatly enhanced by exploitation of microlensing and
gravitational focusing effects.

Drifters may participate in signaling experiments with sites suspected
of harboring communicative intelligence, using a mutually guessable
strategy to set the timing and source direction of query signals.

The Earth-side of the proposed mutually-guessable contact strategy
requires observations in the area of galactic latitude 0 degrees and
galactic longitude 90 degrees (approximately Right Ascension = 21 hours
12 minutes, Declination = 48 degrees 20 minutes) around the time (plus
or minus a few months) of Jupiter and Saturn's closest approach as seen
from the Sun. The next such event occurs approximately on 3 November
2020, and at roughly 19.9 year intervals following.
