2.7 Power Consumption Profile
The LoCate-001 unit has three major operating modes:
Power Off This is the lowest consumption mode to maintain the RTC
and monitor external digital inputs. The current draw from
the supply lines in this mode is less than 100 microamperes at
12 volts.
Armed In this mode the unit checks for scheduled events (not
currently supported), external analog and digital inputs. Any
unused modules are powered down. When processing is not
required the unit runs in the power off state. The current draw
from the supply lines in this mode is nominally 150
milliamperes at 12 volts.
Active This is the full operating mode with both the GPS and the
Cellular Section powered on continuously. The unit monitors
exceptions, receives GPS position fixes and the Cellular
Section is in the standby mode ready to receive any messages.
The Cellular Section transmitter is turned on as required. The
current draw from the supply lines in this mode is nominally
150 milliamperes with periods at 600 milliamperes at 12 volts
when the cellular unit is in full power transmit.
