Abstract: Example embodiments are directed to generating an optimized network of flight paths and an operations volume around each of these flight paths. A network system creates a source network of paths, whereby the source network comprises a set of possible paths between two locations. The network system assigns a cost for traversing each edge of each path of the source network and aggregates the cost for traversing each edge of each path to obtain a cost for each path of the source network. Based on the cost for each path, the network system identifies a path having the lowest cost, whereby the path having the lowest cost is the optimized route between the two locations. The network system then generates an operations volume for the optimized route. The operations volume represents airspace surrounding the optimized route. The operations volume is transmitted to a further system for use.

Abstract: Systems and methods for battery-based aircraft performance are provided. An example computer-implemented method includes accessing, by a computing system, flight plan data for a first flight. Based on the flight plan data, the computing system can compute a first expected power demand on the aircraft's battery system for the first flight. The computing system can access initial battery state data of the aircraft. The computing system can compute, using a battery model, a first capability output based the first expected power demand and the initial battery state. The first capability output can be indicative of a range/ToF of the aircraft for the first flight. The computing system can determine an ability of the aircraft to perform the first flight based on the first capability output and generate an itinerary accordingly. The computing system can transmit, over a network, instructions associated with implementing the itinerary for performance by the aircraft.

Abstract: Disclosed are embodiments for employing off board sensors to augment data used by a ground based autonomous vehicle. In some aspects, the off-board sensors may be positioned on another autonomous vehicle, such as an aerial autonomous vehicle (AAV). The disclosed embodiments determine uncertainty scores associated with ground regions. The uncertainty scores indicate a need to reimage the ground regions. An AAV may be tasked to reimage a region having a relatively high uncertainty score, depending on a cost associated with the tasking.

Abstract: Example embodiments are directed to providing periodic vertiport usage and capacity data exchange, A cloud service system generates, based on historical data, a flight operation set that comprises a simulation of flight operations for time buckets in the future, where the simulation of flight operations include transportation services between vertiports. The system then receives, within a predetermined time period of the time buckets, real-time data including weather forecasts and actual demand for transportation services. The real-time data is analyzed to determine any deviations from the flight operation set for the time buckets. The system then presents the flight operation set including any deviations. Additionally, the system receives, after the time buckets has passed, real-time data indicating actual flight operations, compares the real-time data to the flight operation set to identify deltas, and provides the deltas as feedback to refine the generating of future flight operation sets.
