Abstract:

There is an increasing need to accurately determine the position of a locomotive along a track for advanced train control systems such as Positive Train Control. For locations where Global Positioning System (GPS) reception is not acceptable, inertial navigation can provide the needed information. However, existing inertial navigation systems may be prohibitively expensive due to the high cost of the inertial sensors. The overall goal of this Innovations Deserving Exploratory Analysis (IDEA) project was to develop an inertial navigation system capable of accurately determining the location of a locomotive while using inexpensive MicroElectroMechanical Systems (MEMS) sensors. Navigation and Kalman filtering software was developed with innovative features to improve the performance of the low-cost sensors for rail applications. The algorithms and software were successfully tested with simulated data and verified by the use of recorded data. An inertial measurement system using MEMS accelerometers and gyros was developed and tested. However, the accuracy of the inertial system was too low for it to be used for successful navigation.
