MTI revolutionized the animal tracking world in 1991 with the release of
the 95g PTT-100. This was the PTT that proved it was possible to use
the Argos system to track migrating birds by satellite with low-power
transmitters. Since the debut of the 95g PTT, miniaturization
and advances in microelectronics have allowed us to continually reduce
the size of our PTTs with the goal of providing remote telemetry for all
species, large and small.
