    Abstract: Systems and methods for low-cost HAGL measurement and terrain database updates are provided. In one example, a system includes an image capturing device configured to capture first and second images and a navigation system configured to generate pose data. The system further includes processor(s) communicatively coupled to the image capturing device and the navigation system and a non-transitory, computer-readable medium communicatively coupled to the processor(s) that stores instruction(s) which, when executed by the processor(s), cause the processor(s) to: estimate optical flow between the first and second images; determine rigid flow per image for each depth bin of a group of depth bins based on the pose data, wherein each depth bin corresponds to a particular depth range; and generate a dense depth map by determining a depth bin, for each pixel, that minimizes a difference between the estimated optical flow and the determined rigid flow for the respective pixel.

    Abstract: In some examples, a system includes at least three receivers configured to receive a surveillance packet from another vehicle at respective arrival times. The system includes a first receiver configured to receive a surveillance packet from the other vehicle at a first time. The system also includes a second receiver configured to receive the surveillance packet from the other vehicle at a second time. The system further include a third receiver configured to receive the surveillance packet from the other vehicle at a third time. In addition, the system includes processing circuitry configured to determine a location of the ownship vehicle based on the received surveillance packet and the respective arrival times.
