1.4. Power Consumption
The Iridium Modem typically draws 333mA at 12 volts during
transmission (max. 2500 mA). The standby current is 125mA (12
volts). The C2462 will be used to control power to the modem
with the use of 5V trigger on a datalogger control port (CP:
orange wire, G: Black). It is recommended that a separate power
source be used for the modem to avoid catastrophic loss of data
in case of power failure. The C2462 must draw power directly
from the 12V power supply (power +: Red, power -: Black)

Where it works
Unlike other satellite systems the Iridium satellite system is
located in a low polar orbit, giving the system complete global
coverage.
Their relatively low altitude (780 km) means that they are
situated close to transmitting modems and therefore require less
transmission energy. Additionally, the Iridium network consists of
66 satellites in eleven planes with an extra 6 satellite reserved as
backups. This redundancy potentially gives the iridium system
excellent reliability versus other systems that rely on two or three
satellites.
