A method for coordinating the paths of multiple autonomous vehicles and a vehicle configured to coordinate its path with the path(s) of other vehicles so as to enhance cooperation between the vehicles. The method also enables the vehicles to perform their respective missions more efficiently. The method is applicable to any system in which multiple autonomous vehicles may need to coordinate their paths with each other.

The method of claim 1, wherein the mission requirement assigned to the first autonomous vehicle is a first mission requirement, the method further comprising: receiving, at the first autonomous vehicle, a second mission requirement assigned to the first autonomous vehicle to replace the first mission requirement; andgenerating, at the first autonomous vehicle, a third planned path based, at least in part, on the current position of the first autonomous vehicle and the second mission requirement. 3. The method of claim 1, further comprising: determining, at the first autonomous vehicle, a future position of the first autonomous vehicle along the second planned path of the first autonomous vehicle; andwhen the future position of the first autonomous vehicle is within a predetermined distance of a future position of the second autonomous vehicle along the second planned path associated with the second autonomous vehicle during a future period of time, generating a third planned path for the first autonomous vehicle to avoid a close encounter with the second autonomous vehicle during the future period of time, the third planned path of the first autonomous vehicle not placing the first autonomous vehicle within the predetermined distance of the future position of the second autonomous vehicle at any point along the third planned path of the first autonomous vehicle. 4. The method of claim 1, further comprising: receiving, at the first autonomous vehicle, from a third autonomous vehicle, a planned path associated with the third autonomous vehicle,the generating the second planned path including generating the second planned path of the first autonomous vehicle based, at least in part, on the first planned path associated with the second autonomous vehicle, the planned path associated with the third autonomous vehicle, and at least one of the mission requirement assigned to the first autonomous vehicle or the first planned path of the first autonomous vehicle. 5. The method of claim 1, further comprising: receiving, at the first autonomous vehicle, from the second autonomous vehicle, a third planned path associated with the second autonomous vehicle when the second autonomous vehicle is unable to follow the second planned path due to at least one of an environmental factor or an equipment failure associated with the second autonomous vehicle;generating, at the first autonomous vehicle, a third planned path based on the third planned path associated with the second autonomous vehicle and at least one of the mission requirement assigned to the first autonomous vehicle or the second planned path of the first autonomous vehicle; andtransmitting the third planned path from the first autonomous vehicle to the second autonomous vehicle. 6. The method of claim 1, wherein the second planned path associated with the second autonomous vehicle differs from the first planned path associated with the second autonomous vehicle based, at least in part, on the second planned path of the first autonomous vehicle. 7. The method of claim 1, wherein the second planned path of the first autonomous vehicle incorporates at least one of an evasive horizontal profile, a temporary altitude adjustment, or a temporary speed adjustment into the first planned path. 8. The method of claim 1, wherein the generating the second planned path of the first autonomous vehicle avoids a projected collision with the second autonomous vehicle at a future location along the first planned path. 9.
