    Abstract: Described herein are techniques for determining motion characteristics (e.g., position, velocity, acceleration, etc.) of one or more trains traveling along a train track, such that train control systems may have the information needed to safely operate the trains at higher speeds and with shorter separation between trains. In accordance with various embodiments, systems and methods described herein may be configured to determine a position, velocity, and/or acceleration of a train traveling along a train track. In some embodiments, the motion characteristics may be determined one or more radio frequency antennas onboard the train, such as in communication with one or more anchor nodes positioned adjacent the train track. Alternatively or additionally, in some embodiments motion characteristics may be determined using one or more one or more inertial measurement units (IMUs) onboard the train.
