Programming the satellite trackers

It is a complex business tracking sea turtles. The satellite trackers have to be programmed to ensure efficiency in transmission and longer battery life – this means making them automatically turn on during periods when the turtle is most likely surfacing. I have also programmed them to turn on during the peak times in which Argos satellites are passing over Cape York. There are 5 satellites in total and each pass only lasts 10-15 minutes each day. I have programmed them to go into ‘standby’ mode at 4pm each day and turn off at 10pm. They are then turned on when the turtle surfaces to breath by a change in the conductivity and wet/ dry sensor. This then sends a quick signal to a satellite which is hopefully in range at the time.
