SunSpace was established in 2000 as a spin-off from Stellenbosch University following the successful launch of SUNSAT by NASA with a Delta-II launch vehicle. During the past decade SunSpace has developed and delivered numerous satellite components, subsystems and two flight model satellite, now operational in space. This blog documents the mission of Sumbandila (funded by the DST), launched on a Soyuz-2.1b on 17 September 2009. SunSpace places a high premium on a strong partnership with the South African Government for supplying the ongoing satellite needs of our government.

Fine Sun Sensor image

This image of the sun was taken by die Fine Sun Sensor today.  The sun centroid is then extracted by SW using a region-growing algorithm.  The centroid is required by the more advanced attitude determination estimators in order to 3-axis stabilize the satellite.

Below is a graph depicting the extracted X and Y coordinates of the centroid, calculated 1s apart, for a duration of 1 hour and 4 minutes (total sunlit part of one complete orbit).
