G-IV Inertial Reference System UpgradeThe G-IV aircraft at Armstrong Flight Research Center requires an upgrade to its inertial reference system, which currently operates on the unsupported Honeywell LASEREF II unit. The original equipment manufacturer no longer provides support for this system or any alternative iterations except the LASEREF IV, which is the only compatible replacement approved for the G-IV platform. The acquisition includes three LASEREF IV units, the necessary adapter kit to transition from the legacy system, and full installation services to be carried out by an approved avionics shop to ensure compliance and operational integrity. This procurement is forecasted under the NAICS code 334511 and is managed by NASA’s National Aeronautics and Space Administration through the Armstrong Flight Research Center located at Edwards AFB. The action is intended to restore and maintain critical navigation capabilities, as the existing system is no longer serviceable due to discontinued support from the OEM and third parties.
