DUTY CYCLE: Solar 2g PTTs transmit continuously, rather than operating on an ON/OFF duty cycle as do our other PTTs. During normal operation, the 2g PTT transmits in a power-saving mode in which all messages contribute to Argos-calculated locations, but only every fourth message contains sensor data. As with all of our transmitters, the 2g PTT will not be able to transmit if its battery voltage becomes too low. Normal operation will resume once the PTT is exposed to sufficient sunlight to recharge its battery.
The smallest and lightest solar-powered satellite transmitter to date, this miniature PTT is being used to study several data-deficient and at-risk species, including Spoon-billed Sandpipers and Red Knots. The addition of the Solar 2g PTT to our line of transmitters now grants researchers the potential to conduct long-term satellite tracking studies of birds weighing as little as 67 grams.
