Initialize the Stamp Module
IMPORTANT NOTES
The initialization procedure is required for Modes 2 & 3 Only.
The initialization procedure must be performed prior to operating the Stamp
Module the first time OR if the board has travelled more than 100Km from the last
computed position.
T
he initialization procedure can be performed repeatedly without causing any harm
to the Stamp Module. If unsure, repeat the initialization procedure.
The initialization procedure usually takes seconds to complete but many factors
could cause the initialization procedure to take up to 15 minutes to complete. To
reduce the time required for the initialization process, use the @POS command to
define initial position and uncertainty as described in section 4.1.
