What does IRS stand for?

The Scalable SIRU(tm) is an inertial reference system that supplies critical data that enables the stabilization, pointing and attitude control of satellites and space vehicles.

The pilots did not detect and appropriately arrest the descent soon enough to prevent loss of control," it said, adding that they apparently had no training on what to do if the Inertial Reference System failed, nor if the autopilot unexpectedly disengaged.

The systems include the 131-9[A] APU and a full avionics suite that comprises EGPWS, ACAS II, RDR-4B weather radar, FDRs and CVRs, Quantum Line communications and navigation system and Air Data Inertial Reference System.

In a related case, a different federal court jury in Los Angeles awarded Litton $234 million in damages in February after determining that Honeywell illegally had monopolized the commercial aircraft navigation market for inertial reference systems.

Aircraft flight path and acceleration, derived from the inertial reference system, appear as overlaying the outside real-world view in a true one-for-one relationship, enhancing situational awareness, improving energy management, approach stability and touchdown precision.

Northrop Grumman's LTN-101E Global Navigation Air Data Inertial Reference System (GNADIRS), slated for deployment aboard Airbus commercial jet liners starting in 2006 and possibly sooner on other commercial transport aircraft, delivers a four-fold increase in reliability over traditional navigation systems, while providing significant reductions in weight and power consumption.

Both the AHRS400CB and AHRS500CB were flown on a number of Unmanned Aerial Vehicles prior to introduction and numerous missions were conducted incorporating a $125,000 military-performance ring laser gyro inertial reference system as a truth (control) system.
