  • Publication number: 20210294720
    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.

  • Patent number: 11029158
    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).

  • Publication number: 20210141518
    Abstract: Techniques are disclosed for user interface management in a movable object environment. A user interface manager can request sensor data associated with a movable object from a data manager. The user interface manager can provide the sensor data to one or more user interface elements associated with the user interface element. A first rendering of the at least one user interface element can be caused to be displayed in a user interface, the first rendering determined based on a type or amount of the sensor data associated with the movable object.
