reliable sources of high power-density will be required in future for military
drones and could have applications in biology.
There will also be improved automation. Time-difference of arrival (TDOA)
systems may become available for automated tracking of the smallest VHF tags.
Analyses will become automated to minimize the need for decisions that now
complicate them, leading ultimately to automation of complex modeling sys-
tems. Improvements in reliability and automated decision support will tend
toward radio-tagging techniques that are developed initially by professionals,
then adopted by trained volunteers. Spatially specific population modeling, based
on thrice-annual checks by volunteers, is practical already.
