Abstract
The aim of this article is to estimate the revisiting time of an observated site. The revisiting time is the time elapsed between two successive possibilities of taking an image the same site by the same satellite. First, we suppose that the satellite has a cyclical and heliosynchronical orbit and that the imaging captor observes perpendicularly to the motion of the satellite. Then, we talk about how we can use the results of this algorithm to estimate the revisiting time without a computer and under the constraint of obtaining an image without a great geometrical deformation. To do this, we use the curves calculated by our algorithm and which have in x-axis the latitude of the observated site and in y-axis the view angle of the image. These results could be a great help for scientits who need to simply estimate the operationnal potential of a particular satellite in the field of short revisiting time applications.
