Abstract

A method is disclosed for an unmanned vehicle using a Short Message Service (SMS) to relay information to and from a separate management system is disclosed. All or portions of the payload/data to be transmitted to and from the unmanned vehicle and management system uses this SMS, specifically payload/data that aids in the operation and location determination (such as GPS data) of the unmanned vehicle.

Claims

1. A method for short message service (SMS) between an unmanned vehicle and a cellular network, the method comprising:

compiling a short message from information obtained from at least one of a current location, a speed, an altitude, a destination, and a power reserve of the unmanned vehicle; and

sending the short message on a repetitive interval over a communication path between the unmanned vehicle and the cellular network, the communication path supporting at least one communication protocol;

wherein the short messages are sent from the unmanned vehicle using a first communication protocol, if no reply or conformation received within a time threshold, the short messages are sent via a second communication protocol different from the communication protocol, if still no reply or conformation received within the time threshold, the short messages are sent via the first communication protocol again;

wherein the time threshold is smaller than the repetitive interval;

wherein the short messages are refreshed on the repetitive interval; and

when the power reserve of the unmanned vehicle is below a reserve threshold, the short messages are sent via both the communication protocols and with a reduced repetitive interval.

2. The method of claim 1 wherein the repetitive interval is a predetermined parameter stored within the unmanned vehicle.

3. The method of claim 1 wherein the repetitive interval is determined by a request received at the unmanned vehicle.

4. The method of claim 1 wherein the repetitive interval is dynamically determined based on at least one parameter selected from the group consisting of the current location, the speed, the altitude, the destination, and the power reserve of the unmanned vehicle.
