Dave
is attaching the GPS Platform Transmitter Terminal (PTT) to the
crane's leg while Marty holds the crane. The solar-powered GPS transmitters
are expected to function for 3 to 5 years. We
are
collecting 4 high-resolution GPS fixes per bird bird per day. These
GPS fixes are within about 50 meters of the actual location of the
birds. Data are transmitted to the Argos satellite every 56 hours and
we access these data via a password-protected logon to the Argos Web
site.
