In 1985, development of resonant fiber-optic gyros
began at Litef in Germany and was followed by the
development of interferometric fiber-optic gyros in
1987.
Development of fiber optic IMUs began
simultaneously at Guidance and Control Systems and
at Litef in 1988. Guidance and Control developed the
LN-200 and Litef developed the LCR-92/93 family of
IMUs. Both were in production by 1992. In 1995, Lital
began using the LN-200 in its LISA 200 family of
Attitude and Heading Reference Systems (AHRS).
In 1998, Fibersense started the development of the
IMU 600 for precision pointing applications and the
IMU 200 for missile defense applications.

1995 on the LN-251 INS product. The LN-251 entered
production in 2001 and is now in high rate production.
Navigation Systems Division began development
of the LN-260 product in 2005. This fiber-optic gyro
inertial navigation system was specifically designed
for the F-16 fighter aircraft and it was recently selected
for this aircraft by the U.S. Air Force.
In 2003, Navigation Systems Division began
development of the LTN-101E INS product for the
commercial airline market using fiber-optic gyros. The
LTN-101E is scheduled to be certified on Airbus
aircraft in 2008.
Litef started the development of the LTR-97 in
1997. This unit is a fiber-optic gyro vertical
gyro/directional gyro replacement for the commercial
airline market, which began production in 1999.
