nope - but then again you have to want to be found.
the DASS system when it comes online will be capable of way much more than the current Sat system,
it would be possible to acivate a new generation beacon
remotely to locate a missing plane or boat.
Return messaging is possible, because the 60 bit limit of the current system will not apply.
However, the constraints on DASS - certainly on launch, will be those placed on it by each countries authorities.
New generations will be Return link capable with DASS.
When a new distress event is created, it will be sent to the French Space Agency in Toulouse,
the Return Link provider, and they will then send the acknowledgement of receipt to the satellite
– which will be broadcast through the GPS signal – the Gallileo satellite,
not Copsas Sarsat anymore, the navigation signal itself will contain a specific message dedicated to your beacon,
that will let you know that they have now received a distress alert from your beacon.
You will not have any information about the Local Rescue co-ordination centre being active and dispatching rescue resources, because authorities are afraid of liability.
"Mmm all so well and good relying on the electronic stuff. I Know 4 people who were NEVER rescued even though they had the electronic Gizmo's !!"
Are you referring to the Cheeky Rafiki crew?
Assuming you are, rescues are only possible when assets can reach you to perform that rescue,
and in the context of this post, flares would not have helped them.
If anything, it illustrates the need for full exploitation of the DASS system and Return Link Capability.
An emergency is still an emergency, but information is key. The more you can give a Rescue centre the better.
If your not referring to the above, then I would like to know more about the incident(s) your referring to.
