Hello,
Is anyone aware of anti-collision systems (projects or products) for
gliders
based on GPS and short range radio? Such systems broadcast position at
random times, allowing equipped vehicles (e.g. gliders) to be informed
when
they have a dangerous trajectory relative to other equipped gliders).

I think that most collisions are due to happen when pilots KNOW about each
other i.e. while thermalling.
So we'd have the horn blowing much of the time, still not getting much info
from it.
Of course other problem is on glides, but there the probability is quite
low. The trajectory also may change quite rapidly (as opposed to
power-flying) and I think the GPS-based systems couldn't react that fast to
course and altitude changes.
Still a good idea... at least theoretically
