Transient Detections and Other Real-Time Data Processing from MASTER-VWF Wide-Field Cameras

Figure 10

Parallax of an artificial satellite. Here we show the 4^∘×4^∘ frames of a sky area taken with the MASTER-VWF4 Northern and Southern cameras. Triangulation yields a height of 𝐻_satell∼4500 km. Given the accuracy of astrometric measurements for strip-shaped objects, 𝜎^line_astrom∼20^′′, and the baselength of Δ𝑙=702 m, the maximum height that can be determined via triangulation is 𝐻_max=Δ𝑙 * arcsin(𝜎^line_astrom)∼10000 m.
