Optimized global positioning system correction message for interoperable train control messaging transport

A back office (BO) server for optimizing an error correction message for interoperable train control messaging transport (ITCM), comprising:

• a transceiver;
• a storage;
• a processor operatively coupled to the transceiver and the storage, the processor configured to:
• simultaneously receive:
• a first message containing error correction data from a reference station, and
• a second message containing satellite identification information from a rover,
• determine satellites that are common to the error correction data and the satellite identification information,
• normalize the data based on the determined satellites,
• generate an optimized error correction message based on the normalized data of the determined satellites, and
• transmit the standardized error correction message to the rover.
