receiving emergency instructions from the ATC system;
storing the emergency instructions in memory, the emergency instructions configured to be implemented during an emergency situation;
detecting when communication with the ATC system via the primary wireless network is disrupted;
responsive to detecting when the communication with the ATC system via the primary wireless network is disrupted, implementing a network switchover procedure to attempt to reestablish communication to the ATC system via a backup wireless network, the backup wireless network associated with a second cell tower; and
responsive to a failed attempt to reestablish communication to the ATC system via the backup wireless network, implementing the emergency instructions.
2. The method of claim 1 , further comprising:
during the process of implementing the emergency instructions, attempting to reestablish communication to the ATC system via one of the primary wireless network and the backup wireless network; and
receiving instructions from the ATC system.
3. The method of claim 1 , wherein the communication is disrupted due to one of a network disturbance and an outage.
4. The method of claim 1 , wherein the emergency instructions comprise an altitude to maintain and a flight plan to maintain until communication is reestablished.
5. The method of claim 1 , wherein the emergency instructions comprise nearby landing zones to proceed to.
6. The method of claim 1 , wherein the emergency instructions comprise continuing to a destination as planned.
7. The method of claim 1 , wherein the emergency instructions comprise immediate landing at one of a plurality of designated locations.
8. The method of claim 1 , wherein the emergency instructions comprise flying lane information.
9. The method of claim 1 , wherein the primary wireless network comprises a first wireless provider network and the backup wireless network comprises a second wireless provider network.
10. The method of claim 9 , wherein the first wireless provider network and the second wireless provider network comprise cellular networks.
11. The method of claim 9 , wherein the UAV comprises a wireless interface configured to communicate with the first wireless provider network via the first cell tower and with the second wireless provider network via the second cell tower.
12. The method of claim 1 , wherein the communicating with the ATC system comprises:
providing flight information to the ATC system; and
receiving instructions and updates from the ATC system for real-time control.
13. The method of claim 12 , wherein the flight information comprises weather and obstacle reporting, speed, altitude, location, and direction, and wherein the instructions and updates relate to separation assurance, traffic management, landing, and flight plan.
14. An Unmanned Aerial Vehicle (UAV) configured for network switchover to communicate with an Air Traffic Control (ATC) system, the UAV comprising:
one or more rotors disposed to a body and configured for flight;
wireless interfaces including hardware and antennas configured to communicate with a primary wireless network and a backup wireless network of a plurality of wireless networks, each of the plurality of wireless network being associated with communication equipment different from the communication equipment associated with the other wireless networks;
a processor coupled to the wireless interfaces and the one or more rotors; and
memory configured to store network switchover instructions that, when executed, cause the processor to:
communicate with the ATC system via the primary wireless network;
receive emergency instructions from the ATC system, the emergency instructions configured to be implemented during an emergency situation;
store the emergency instructions in the memory for use during the emergency situation;
detect a communication disruption with the ATC system via the primary wireless network;
responsive to detection of the communication disruption, implement a network switchover procedure to attempt to reestablish communication to the ATC system via the backup wireless network; and
responsive to a failure to reestablish communication to the ATC system via the backup wireless network, implement the emergency instructions.
15. The UAV of claim 14 , wherein the primary wireless network comprises a first wireless provider network and the backup wireless network comprises a second wireless provider network.
16. The UAV of claim 15 , wherein the first wireless provider network and the second wireless provider network comprise cellular networks.
17. The UAV of claim 14 , wherein, to communicate with the ATC system, the wireless interfaces are configured to:
provide flight information to the ATC system; and
receive flight instructions and updates from the ATC system for real-time control.
18. The UAV of claim 17 , wherein the flight information comprises weather and obstacle reporting, speed, altitude, location, and direction, and wherein the flight instructions and updates relate to separation assurance, traffic management, landing, and flight plan.
19. The UAV of claim 14 , wherein the ATC system is configured to monitor or control the flights of multiple UAVs.
20. The UAV of claim 14 , wherein the network switchover instructions, when executed, cause the processor to implement the emergency instructions in response to failed attempts to reestablish communication to the ATC system via the primary wireless network and the backup wireless network.
