Comment
Supplying position assistance that is inaccurate by more than the specified
position accuracy, may lead to substantially degraded receiver performance.
This message allows the delivery of initial position assistance to a receiver in cartesian ECEF
coordinates. This message is equivalent to the UBX-MGA-INI-POS_LLH message, except
for the coordinate system. See the description of AssistNow Online for details.
