Methods and systems for vehicle position reporting and emergency messaging

An on-board communications device for vehicle information reporting of a vehicle, the on-board communications device comprising:

• a memory storing instructions;
• and
• a processor executing the instructions to perform a process including:
• obtaining GNSS data to determine position information, altitude information, speed information, track information, or vertical rate information for the vehicle, the obtained GNSS data being received by the GNSS receivers;
• receiving inputs from timers, sensors, or a user interface of the vehicle;
• determining whether to transmit a message based on rules applied to the obtained GNSS data and the received inputs;
• in response to determining to transmit the message, compiling the message based on a message content rule, the message being configurable with respect to a maximum size of a radio-determination-satellite service (RDSS) message of the satellite system, the message including an emergency message when the rules indicate an emergency situation;
• and
• transmitting the message via the satellite communication transceiver to a satellite of the satellite system.

A non-transitory computer-readable medium storing instructions that, when executed by an on-board communications device, cause the on-board communications device to perform a method for vehicle information reporting of a vehicle, the method comprising:

• obtaining GNSS data to determine position information, altitude information, speed information, track information, or vertical rate information for the vehicle, the obtained GNSS data being received by the GNSS receivers;
• receiving inputs from timers, sensors, or a user interface of the vehicle;
• determining whether to transmit a message based on rules applied to the obtained GNSS data and the received inputs;
• in response to determining to transmit the message, compiling the message based on a message content rule, the message being configurable with respect to a maximum size of a radio-determination-satellite service (RDSS) message of the satellite system, the message including an emergency message when the rules indicate an emergency situation;
• and
• transmitting the message via the satellite communication transceiver to a satellite of the satellite system.
