Testifying before Congress in May, Stanford University professor Brad Parkinson–the chief architect of GPS and the original GPS program manager before his retirement from the USAF–echoed the concern of the Government Accountability Office (GAO) that there will be insufficient backup satellites to fill gaps in the constellation before the DOD’s forecast 2014 launches of its next-generation GPS III units. (see AIN, June, page one.)

Airbus engineers are never satisfied, and customers of the European airframe builder should have only one response... thank goodness. Despite myriad technological and manufacturing obstacles, the European consortium of Germany, France and Spain successfully built, flew and put into production the largest commercial aircraft in the world, the A380, and the airframer currently has orders for 200 of the double-decker jetliners.

Honeywell has been chosen by Embraer to provide the air-conditioning and temperature-control system for the Brazilian manufacturer’s Legacy 450 and Legacy 500 executive jets. The Legacy’s air- conditioning system will use bleed air from either the Honeywell 36-150 auxiliary power unit or the Honeywell HTF7000 engines to cool the cabin. According to Honeywell, the AC-5000 series of environmental control systems deliver high reliability.

Atlantic Inertial Systems (AIS) has introduced a new generation of ruggedized solid-state inertial MEMS (micro electromechanical systems). The system improves noise performance and halves the bias of a current inertial measurement unit or single-axis rate sensor. This makes them compatible with long-endurance missions, the company claims.
