Abstract Satellite Laser Ranging (SLR) is a powerful technique able to measure spin rate and spin axis orientation of the fully passive, geodetic satellites. This work presents results of the spin determination of LARES – a new satellite for testing General Relativity. 529 SLR passes measured between February 17 and June 9, 2012, were spectrally analyzed. Our results indicate that the initial spin frequency of LARES is f0 =86.906mHz (RMS=0.539mHz). A new method for spin axis determination, developed for this analysis, gives orientation of the axis at RA=12h22m48s (RMS=49m), Dec=−70.4° (RMS=5.2°) (J2000.0 celestial reference frame), and the clockwise (CW) spin direction. The half-life period of the satellite’s spin is 214.924days and indicates fast slowing down of the spacecraft.
