Systems and method of calibrating a range measurement system for a vehicle mounted on a guideway are disclosed. In some embodiments, a method includes: measuring a first time of transmission (TOT) between a first internal component of an on-board range measurement device and a second internal component of a wayside range measurement device. The first TOT is compared with a first pre-determined time. A health of the range measurement system is determined based on a difference between the first TOT and the first pre-determined time.

Systems and methods of calibrating a range measurement system

Systems and methods of calibrating an Inertial Measurement Unit (IMU) on a vehicle are disclosed. In some embodiments, a first tilt angle of the IMU is measured with the IMU while the vehicle is stationary. A second tilt angle of the IMU is measured with an inclinometer or tilt sensor while the vehicle is stationary. The orientation of the IMU is corrected based on the first tilt angle and the second tilt angle.

System and method of calibrating an inertial measurement unit on a vehicle

A method for determining rail vehicle location and identifying obstacles, which includes operations of transmitting, from at least two vehicle beacons on a first vehicle, a ranging signal to at least two external beacons; receiving, at the at least two vehicle beacons, a return signal from the at least two external beacons; and determining, based on the return signal from the at least two external beacons, a position of each of the external beacons with respect to the at least two vehicle beacons of the first vehicle.
