Field of view is the area of the inspection captured on the camera’s imager. The size of the field of view and the size of the camera’s imager directly affect the image resolution (one determining factor in accuracy). Working distance is the distance between the back of the lens and the target object.
Each camera has a 24° × 24° field of view, a 100 mm (3.9 in) effective pupil diameter, a lens assembly with seven optical elements, and a bandpass range of 600 to 1000 nm. [34] [3] The TESS lenses have a combined field of view of 24° × 96° (2300 deg 2, around 5% of the entire sky) and a focal ratio of f/1.4.
In remote sensing, ground sample distance ( GSD) in a digital photo of the ground from air or space is the distance between pixel centers measured on the ground. For example, in an image with a one-meter GSD, adjacent pixels image locations are 1 meter apart on the ground. [1] GSD is a measure of one limitation to spatial resolution or image ...
Satellite geodesy is geodesy by means of artificial satellites —the measurement of the form and dimensions of Earth, the location of objects on its surface and the figure of the Earth 's gravity field by means of artificial satellite techniques. It belongs to the broader field of space geodesy. Traditional astronomical geodesy is not commonly ...
A star tracker is an optical device that measures the positions of stars using photocells or a camera. [ 1] As the positions of many stars have been measured by astronomers to a high degree of accuracy, a star tracker on a satellite or spacecraft may be used to determine the orientation (or attitude) of the spacecraft with respect to the stars.
290 km field of view; Free and open data policy; To achieve frequent revisits and high mission availability, two identical Sentinel-2 satellites (Sentinel-2A and Sentinel-2B) operate together. The satellites are phased 180 degrees from each other on the same orbit. This allows for what would be a 10-day revisit cycle to be completed in 5 days. [5]
Photo interpretation at the U.S. National Photographic Interpretation Center during the Cuban Missile Crisis. Aerial photographic and satellite image interpretation, or just image interpretation when in context, is the act of examining photographic images, particularly airborne and spaceborne, to identify objects and judging their significance.

The Near Earth Object Surveillance Satellite ( NEOSSat) [8] is a Canadian microsatellite using a 15-cm aperture f/5.88 Maksutov telescope (similar to that on the MOST spacecraft), with 3-axis stabilisation giving a pointing stability of ~2 arcseconds in a ~100 second exposure. It is funded by the Canadian Space Agency (CSA) and Defence Research ...
