INTRODUCTION

The LASEREF
R
reference system that computes aircraft position, velocity, heading and
attitude.
This brief description is a summary of the operation of the LASEREF
II and III. For a detailed description of system operation, refer to
Honeywell Pub. No. M95--8172--000 (LASEREF
YG1779) or M28--3343--001 (LASEREF
All IRSs have an inertial reference unit (IRU), an IRU mounting rack,
and a mode select unit (MSU). Each IRS requires a dedicated +24 V
dc backup battery.
