Inertial Navigation System Repair

An Inertial Navigation System uses motion sensors in the form of accelerometers, rotation sensors in the form of gyroscopes and a computer to calculate position, orientation, and velocity of an aircraft with no need for external references. 

Inertial sensors can be supplemented by barometric altimeters, magnetic sensors, and/or speed measuring devices. Inertial navs, GPS, barometric altimeters, magnetic sensors, and/or speed measuring devices all may require repair and testing solutions and AESG has you covered. AESG repairs, overhauls and refurbishes INS’ used on fixed-wing, rotary-wing and unmanned systems.

Inertial navigation system testing and evaluation

Functional testing of the INS system is performed to identify what the issues/problems are and determine the cause. In the event this requires teardown (taking apart the system to determine the cause) we complete the teardown and identify the cause as well as provide a recommendation and cost to repair to be weighed against the cost of replacement. 

  • Go / No Go Testing
  • Card Edge Functional Test
  • Subsystem testing
  • Acceptance testing

Navigation systems provide input to flight directors, HUDS, and other pilot systems.  End use simulators are used to replicate/simulate these devices to test and verify the accuracy of repairs to an INS.

Development of automated testing procedures for a diagnostic testing environment –  Navigation systems may require external position and velocity information to test functionality and, to run the item continuously over a period of time.  In this scenario we develop automated test procedures that can run with no input or minimal manual input and record performance data.

Over time, both systems and the essential components necessary for maintaining operational functionality can become obsolete. To ensure the continued functionality of these items, it becomes crucial to anticipate and explore options for replacing various parts and systems. This proactive approach may include the acquisition and storage of components to preemptively manage potential issues through timely repairs. Moreover, in certain scenarios, the development of substitutes with equivalent form, fit, and function becomes essential for components or systems that are beyond repair.

Intertial Navigation System Testing and Repair

Inertial Navigation Systems

Inertial Navigation Systems (INS) are commonly used in aircraft, ships, submarines and other vehicles that provide continuous, autonomous navigation by measuring the vehicle’s accelerations and rotations. INS is particularly valuable when other external navigation references, such as GPS signals, are unavailable or unreliable.
