OPERATING OCTANS NANO
As soon as OCTANS NANO is powered up, it starts its alignment phase.
Alignement uses as initialization parameters the "Manual position" and "Manual velocity" (see page 11) saved in the
nonvolatile memory of the system; alternatively, if available, any external input position and velocity.
During the alignment phase, heading and attitude data are available, but have not reached full accuracy.
Specified accuracy on heading, roll and pitch is reached at the end of the alignment phase.

Important
OCTANS NANO is delivered with default latitude set to iXBlue’s factory location.
Without user update or external GPS connected, OCTANS NANO will start seeking north with France latitude, which
may be quite different from the current latitude.
Latitude has to be modified by the user (see page 11). Once this modification is performed, it is recommended to save
it and restart the system. This procedure allows OCTANS NANO to enter the correct latitude value as an input in the
North finder algorithm as soon as computation starts. OCTANS NANO will then reach full accuracy after the
alignment phase.
Otherwise OCTANS NANO will not perform according to its specification.
At any power supply outage, OCTANS NANO restarts its full alignment process. It is recommended to secure power
supply on UPS.
