Copernicus Standby Current
When the Copernicus GPS Receiver is sent a command to go into Standby Mode,
there is a period of time between 10 and 200 ms (milli seconds) when the power
supply still has to supply almost full operating current. Only after this period has
elapsed will the current draw go down to the specified standby current which is
typically 8.5 uA (micro Amps).
