# SWSU-55 satellites – determination of the spin rate

I am currently working on determining the spin rate of the SWSU-55 satellites. You see from most SSTV images that all SWSU-55 satellites spinning very fast. Now we are lucky and can read the angular velocity (xyz axis) from the beacon. This shows that the satellite is rotating in all 3 axes, i.e. it is […]
