    Abstract: Solar modules including a solar panel, a sensor for acquiring a power generation state of the solar panel, and a power generation control unit for controlling power generation of the solar panel based on the power generation state are connected to each other. A scan control device for controlling a scan process for scanning an output voltage of each solar panel executed by each power generation control unit to search for a maximum power point includes a determination unit for determining whether or not a power generation state of each solar panel satisfies a predetermined condition, and an instruction unit for instructing a power generation control unit of a solar panel to be controlled based on a result of a scan process in a specific solar module when there is a solar module to be controlled whose power generation state of the solar panel does not satisfy the predetermined condition.

    Abstract: A method for controlling the orientation of a solar module including a single-axis solar tracker orientable about an axis of rotation, and a photovoltaic device supported by said tracker and having upper and lower photoactive faces, including: measurement of a distribution of the solar luminance called incident luminance originating from the incident solar radiation coming from the sky to reach the upper face, said distribution being established according to several elevation angles; measurement of a distribution of the solar luminance called reflected luminance originating from the albedo solar radiation corresponding to the reflection of the solar radiation on the ground to reach the lower face, said distribution being established according to several elevation angles; determination of an optimum orientation considering the measurements of said distributions of the incident and reflected solar luminance; and servo-control of the orientation of the module on said optimum orientation.

    Abstract: Systems and methods for pointing photovoltaic arrays for optimal power generation. One or more methods among a plurality of methods for pointing an array may be used by a spacecraft control system to point the array. Example methods to use to point the photovoltaic array relate to analyzing current output, analyzing image data, and analyzing computational knowledge of reflective bodies or light sources. The spacecraft may be further controlled to reduce shadow by re-orienting, receiving light reflected off spacecraft, and orienting a photovoltaic array relative to incoming light sources based on topographic properties of the array such as cell grooves.

    Abstract: A method and system determines object orientation using a light source to create a shadow line extending from the light source. A camera captures an image including the shadow line on an object surface. An orientation module determines the surface orientation from the shadow line. In some examples a transparency imperfection in a window through which a camera receives light can be detected and a message sent to a user as to the presence of a light-blocking or light-distorting substance or particle. A system can control illumination while imaging an object in space using a light source mounted to a support structure so a camera captures an image of the illuminated object. Direct illumination of the camera by light from the light source can be prevented such as by blocking the light or using a light-transmissive window adjacent the camera to reject light transmitted directly from the light source.

    Abstract: A management server in communication with one or more object tracking devices is disclosed. The management server may receive location information, configuration information, and orientation information associated with the one or more object tracking devices. Based at least in part on the location information, the management server may receive weather information associated with the locations of the one or more object tracking devices. Based at least in part on the location information, the weather information, the configuration information, and the orientation information, the management server can determine power generated and power consumed by the one or more object tracking devices, which then can be used to determine estimated operation time for the one or more object tracking devices.

    Abstract: Analyzing electro-optical imagery from a telescope observing one or more satellites includes capturing one or more images of a plurality of stars and the one or more satellites, and sequentially or randomly selecting each one of a plurality of diagonal lines of pixels in the one or more images. The plurality of diagonal lines of pixels represent one of the plurality of stars in the one or more images. Additionally, a moving average filter is applied to the selected one of the plurality of diagonal lines of pixels to find a location of one of the plurality of start on an x- and y-axis coordinate. Furthermore, the location of the one of the plurality of stars is provided in the one or more captured images to be cross referenced with angular coordinates and radiometric quantities in stellar catalogs.
