High Speed Rail IDEA Project 14 [Completed (IDEA)]

Low Cost Multiple Sensor Inertial Measurement Sensor for Locomotive Navigation

  Project Data
Funds: $84,691
Staff Responsibility: Chuck Taylor
Effective Date: 6/30/1998
Completion Date: 12/1/2008
Fiscal Year: 1998

This project included the development and field testing of an Inertial Navigation System for locomotive navigation.  The system used a distributed array of MicroElectroMechanical Systems (MEMS) accelerometers configured to provide both linear and rotational data, thus eliminating the need for gyros.  A design prototype was laboratory and field tested.  Based on these test results, a follow-on project was conducted (HSR-27) to develop and field test a production prototype.
