摘要： A system and method of vehicular wireless communication over a Dedicated Short Range Communication service band is provided. The system includes a vehicle having a navigation means, a processor, and a communication means for transmitting a message via a wireless communications link. The system includes a control channel for communication a safety communication and a service channel for communicating a non-safety communication. The control channel is subdivided into a contention-free period having a safety exchange interval of time for transmitting a safety communication and a contention period having a non-safety service interval of time for transmitting a non-safety communication. The system further includes an access point in communication with the vehicle via the communications link within region. The method includes the steps of determining if the vehicle is within communications range of the region, determining if the vehicle is registered with the access point, and if the vehicle is within the communications range of access point, determining if a current time is within the safety exchange interval, and transmitting the safety communication by each registered vehicle during the safety exchange interval at the predetermined time for each registered vehicle. The method further includes the steps of determining if the safety communication exchange by every registered vehicle is completed, and permitting the vehicle to leave the control channel if the safety communication exchange is complete, and determining if a current time is within a contention period, and transmitting the non-safety communication if the current time is within the contention period.

摘要： A system and method of vehicular wireless communication over a Dedicated Short Range Communication service band is provided. The system includes a vehicle having a navigation means, a processor, and a communication means for transmitting a message via a wireless communications link. The system includes a control channel for communicating a safety message and a service channel for communicating a non-safety message. The control channel is subdivided into a contention-free period having a safety exchange interval and a contention period having a non-safety service interval. The system further includes a dedicated group manager that partitions the vehicles into groups. The method includes the steps of determining if the vehicle is within communications range of the region, determining if the vehicle is registered with the group manager, if the vehicle is within the communications range of the group manager, determining if a current time is within the safety exchange interval, and transmitting the safety communication by each registered vehicle during the safety exchange interval at the predetermined time for each registered vehicle. The method further includes the steps of determining if the safety communication exchange by every registered vehicle is completed, and permitting the vehicle to leave the control channel if the safety communication exchange is complete, and determining if a current time is within a contention period, and transmitting the non-safety communication if the current time is within the contention period.

摘要： A flight processor that calculates a 4-dimensional trajectory having a sequence of two or more position, time and cost (x, y, z, t, c) tuples that minimize a defined cost. Some embodiments generate cost-optimized trajectories with simple or complex constraints and bounds such as fixed AGL altitude; minimum AGL altitude; maximum AGL altitude; minimum MSL; maximum MSL; avoidance of restricted airspace; adherence to non-restricted airspace such as easements; adherence to ground-based guideways, if applicable; and the constraint to maintain adequate radio frequency signal-to-noise needed for communications to the ground station or backhaul systems. Constraint-enabled minimization of trajectory cost may leverage the aircraft's energy model; current atmospheric data (most notably wind vector data along the trajectory path); continuous-time and/or event-based risk models and fault trees; blacklisted and white-listed geo-fence boundaries; defined easements; and known or estimated RF signal-to-noise (SNR) minimum values needed for one or two-way communications.
