Abstract: A central payload manager device may include a network switch, a central payload manager processing device, a plurality of connecting interfaces, a plurality of sensor processing devices connected to corresponding ones of the connecting interfaces and to the network switch, a cell modem or radio link connected to one or more of the connecting interfaces and to the network switch, a data storage device connected to the processing device, wherein the data storage device is configured to receive and store infoimation from the plurality of sensor processing devices and from the cell modem or radio link via the network switch and the central payload manager processing device; and an iridium modern connecting to the central payload manager processing device and to a corresponding one of the connecting interfaces, wherein the iridium modem is configured to receive and transmit the stored information from the data storage device to an iridium antenna.

Abstract: Systems and methods may include tracking one or a plurality features across a decreasing scale of tiled sets of one or more images. Aspects may include generating point data for each of the tracked features based on a coordinate system relative to the first camera or the second camera, and transforming the point data to a Global Positioning System/Inertial Navigation System (GPS/INS) coordinate system based on (1) an origin of a first GPS device coupled to the first camera and (2) a rotation of the first camera relative to an INS device coupled to the first camera. Aspects may include generating, based on the transformed point data, a geodetic mapping function, determining, based on the geodetic mapping function, georegistered coordinates of the tracked features, using the georegistered coordinates of the tracked features to characterize the water flow.
