Initialization Packets to Speed Start-up
If you are not supplying the receiver with battery power when main power is off, you
can still “warm-start” the receiver by sending the following sequence of commands
after the receiver has completed its internal initialization and has sent Packet 82. Hot
start times can be achieved using packet 0x38-06 to upload the ephemeris. Only time
and position are necessary for the hot start since the almanac and ephemeris are
stored in flash. Position is also stored in flash which improves first fix accuracy.

Packets Output at Power-Up
The following table lists the messages output by the receiver at power-up. After
completing its self-diagnostics, the receiver automatically outputs a series of packets
which indicate the initial operating condition of the receiver. Messages are output as
listed in the table below. After Packet 82 is output, the sequence is complete and the
receiver is ready to accept commands.
