光电惯性技术的发展及现状
 What Do Inertial Sensors Measure?
 These papers address fundamental questions on the
definition of parameters measured by inertial sensors;
inertial angular rate measured by gyros and specific
force measured by accelerometers. Implicit to the
definition for these parameters is the existence of an
inertial frame of reference.

 What Do Inertial Sensors Measure?
 Gyros measure angular rate relative to "non-rotating
inertial space". What is this space and what does non-
rotation mean when rotation itself is defined as a
relative angular measurement between two reference
spaces?

 What Do Inertial Sensors Measure?
 We have been taught that specific force measured by
accelerometers is "total acceleration minus gravity". Is gravity
an absolute or relative parameter? If it is a relative term,
relative to what? What is total acceleration? Acceleration is
defined as the time rate of change of velocity relative to a
reference inertial velocity, and velocity is defined as the time
rate of change of position relative to a reference inertial
position. But what is inertial velocity and position? "Inertial"
implies non-change, but non-change relative to what?
