Systems and methods for unmanned aerial vehicle (UAV) navigation are presented. In a preferred embodiment, a UAV is configured with at least one flight corridor and flight path, and a first UAV flight plan is calculated. During operation of the first UAV flight plan, the UAV visually detects an obstacle, and calculates a second UAV flight plan to avoid the obstacle. Furthermore, during operation of either the first or the second UAV flight plan, the UAV acoustically detects an unknown aircraft, and calculates a third UAV flight plan to avoid the unknown aircraft. Additionally, the UAV may calculate a new flight plan based on other input, such as information received from a ground control station.

1. A method for navigation for an unmanned aerial vehicle (UAV) equipped with a processor, a camera, a wireless network interface and at least one acoustic sensor and a memory device storing data representing at least one flight corridor; and data representing at least one flight path, the method comprising: at the processor, calculating a first flight plan to avoid the at least one flight corridor and the at least one flight path,flying the UAV according to the first flight plan,calculating a second flight plan based on the first flight plan and input from multi-modal logic stored in the memory device based on signals received from the camera and at least one acoustic sensor and flying the UAV according to the second flight plan,wherein the camera detects navigational signals in the range of at least one of visible light or infrared light frequencies, and wherein the processor detects at the at least one acoustic sensor noise associated with an unknown aircraft;at the wireless network interface, receiving information transmitted from at least one ground control station; andat the processor, calculating a third flight plan, based on the second flight plan and the information received from the ground control station and flying the UAV according to the third flight plan. 2. The method of claim 1, wherein the at least one flight corridor comprises a commercial aircraft flight corridor. 3. The method of claim 1, wherein the flight corridor comprises at least one of a waypoint, a vector, a width centered upon the vector, an altitude range, and a time range. 4. The method of claim 1, wherein the at least one flight path comprises a UAV flight path. 5. The method of claim 1, wherein the flight path comprises at least one of a waypoint, a vector, a width centered upon the vector, an altitude range, and a time range. 6. The method of claim 1, wherein the input from the camera indicates an obstacle to the first flight plan, and wherein the second flight plan avoids the obstacle. 7. The method of claim 1, wherein calculating a third flight plan comprises at least one of the UAV changing direction and the UAV changing speed compared to the second flight plan. 8. The method of claim 1, wherein the wireless network is a point to point network between the UAV and the friendly UAV. 9. The method of claim 1, wherein the wireless network is a broadcast network. 10. An unmanned aerial vehicle (UAV) comprising: a processor;a camera configured to detect navigational signals in the range of at least one of visible light or infrared light frequencies;at least one acoustic sensor configured to sense acoustic signals;a memory containing: data representing at least one flight path of a different aircraft;data representing at least one flight corridor;program instructions executable by the processor to calculate a first flight plan to avoid the at least one flight plan and the at least one flight corridor and to store the first flight plan in the memory;program instructions executable by the processor for the UAV to fly according to the first flight plan;multi-modal logic executable by the processor to calculate a second flight plan based on the first flight plan and input from the camera and at least one acoustic sensor; andprogram instructions executable by the processor for the UAV to fly according to the second flight plan,wherein the UAV is capable of vertical takeoff and landing;a wireless network interface; andthe memory further comprising: program instructions executable by the processor to receive flight plan information from other UAVs via the wireless network interface;program instructions executable by the processor to calculate a third flight plan based on the second flight plan and the received flight plan information; andprogram instructions executable by the processor for the UAV to fly according to the third flight plan. 11. The UAV of claim 10, wherein the UAV is a ducted fan UAV.
