摘要:
The invention enables the average user of an internet-capable mobile telephone (1), by evaluation of the detected or input location coordinates, the calendar dates and the time of day and by means of detected and/or input data for the real horizon, to also predict the position of the sun and the solar radiation to be expected for said location for a defined period of time. The invention relates to a device for pre-determining the solar radiation in a defined location, by means of an internet-capable mobile telephone (1) provided with an image recording device (6), an gravitational acceleration sensor and a compass application, the mobile telephone (1) also being provided with a laser (4) for recording the real horizon, and a module for calculating the position of the sun such that the course of the solar radiation can be determined, for a defined point in time and/or period of time, in the location defined by location coordinates, on the basis of location coordinates, calendar dates and data relating to the real horizon.

A method and apparatus for autonomous navigation for deep space missions using the sun as the reference body and determining the spacecraft orbit based on observations made on the sun using onboard instruments. Two types of observation data, the direction of the spacecraft relative to the sun as a function of time and the optical Doppler shift due to the motion of the spacecraft relative to the sun, can be used for the spacecraft orbit determination. A dual imaging system which functions as a sun imager taking images of the sun against star backgrounds during the cruise phase and as a regular optical imager taking pictures of the targeting planetary body during the approaching phase is also described.

An instrument (20) determines the attitude of a spacecraft (3) on which it is mounted, by interacting incident light (11) from the Sun with one or more light conditioning elements (12) and thereby forming a diffraction pattern at a photo- sensitive detector (13). The intensity distribution of light on the detector (13) is dependent on the angle of incidence of the light (11). An on-board computer (16) determines a direction vector to the Sun based on the light diffraction pattern detected by the detector (13).

摘要:
This invention deals with the general topic of adaptive non-imaging tracking of the sun. A transmission-mode electro-optical system is presented for solar energy tracking and col¬ lection. The scale of the system may range from small portable systems to large-scale industrial power plants used for the production of environmentally benign energy. It maybe integrated di¬ rectly into buildings and other platforms without the need for heliostats to hold photovoltaic cells or other energy conversion devices above the building or other host platform. It makes solar energy harvesting systems practical by allowing the separation of tracking, collection, concentration, ag¬ gregation, distribution, and energy conversion. This novel system is unique and distinct from other sun tracking and energy conversion systems because it allows adaptive solid-state electronics to be used in place of conventional mechanical tracking heliostats. Furthermore, it is highly precise and therefore allows very high levels of concentration to be achieved in an dynamic environment. It is also cost effective because it leverages integrated opto-electronics instead of mechanical devices to perform sun tracking.

摘要:
Die Bestimmung des Sonnenstandes und der Sonneneinstrahlung ist im Stand der Technik seit vielen hundert Jahren, etwa aus der Seefahrt und der Navigation bekannt. Heutzutage ist es darüber hinaus möglich, anhand von entsprechenden Tabellenwerken oder mittels entsprechender Software unter Berücksichtigung der tabellarischen Daten für jeden durch Ortskoordinaten definierten Ort den Sonnenstand zu einem definierten Zeitpunkt sowie den Verlauf der weiteren Sonneneinstrahlung mit erheblicher Genauigkeit vorherzusagen. In allen Fällen sind hierzu aber entsprechende Spezialgerätschaften erforderlich. Die Erfindung versetzt den Durchschnittsbenutzer in die Lage eines internetfähigen Mobiltelefons (1) unter Auswertung der erfassten oder eingegebenen Ortskoordinaten, der Kalenderdaten und des Zeitpunktes sowie mittels erfasster und/oder eingegebener Daten zum realen Horizont ebenfalls den Sonnenstand und die für den besagten Ort zu erwartende Sonneneinstrahlung für einen definierten Zeitraum vorherzusagen.
