Abstract: A system for managing communication with a movable object includes one or more processors configured to receive a request for movable object data from a requester in a movable object environment, determine whether movable object data corresponding to the request is available in a cache associated with a movable object manager, and, in response to determining that the movable object data is available in the cache, provide the movable object data in the cache to the requester.

Abstract: A system for tracking and analyzing performance of a movable object and methods of making and using the same. Movable object performance can be tracked by creating a process log for a movable object manager of the movable object, and creating a movement record of the movable object for comparison to the process log. The process log can include, for example, records of application call processes to a movable object interface, protocol call processes transmitted to and from the movable object, and/or metadata. A movable object event can be analyzed by correlating the process log with the movement record. The present systems and methods are particularly suitable for tracking and analysis of unmanned aerial vehicles (UAV).

Abstract: A method of tracking performance of a movable object includes creating a process log for a movable object manager of the movable object, the movable object manager operating in a software environment; creating a movement record of the movable object from two or more sensors including two or more of a global positioning system (GPS) sensor, a motion sensor, an inertial measurement unit (IMU), a proximity sensor, an image sensor, an attitude and heading reference system (AHRS), a radar sensor, a lidar sensor, an ultrasound sensor, and an infrared sensor; and transmitting at least one of the process log or the movement record to a movable object monitoring station.

Abstract: A method for managing communication with a movable object includes receiving a request for movable object data from a requester in a movable object environment. The request includes a movable object data key that has data fields configured to identify a movable object component that corresponds to the movable object data. The method further includes determining whether movable object data corresponding to the request is available in a cache by determining whether the movable object data corresponding to the movable object data key exists in the cache and, in response to determining that the movable object data is available in the cache, providing the movable object data in the cache to the requester.
