End of the road for Iolo?

20 Aug 2012

Since Iolo was tracked heading south over Libya on 5th August, we have received only one further unconfirmed location for him. This was four days later and placed him in northern Chad. Not only would we have expected him to have completed his desert crossing by then but his tag had lost charge in the intervening four days. Furthermore, during the transmission period prior to this final location being received, only two messages were received from his tag, neither of which was good enough to result in a location being estimated, despite his tag still having had some charge at that time. This suggests that it was not in a position to transmit clearly to passing satellites – its antenna could have been on the ground for instance. Taken together, these pieces of information suggest that Iolo died during his desert crossing, probably in northern Chad.
