Spectroscopic observations of radial velocity variations in the dwarf nova SS Cygni are presented, and the observing and analysis techniques are discussed in detail. Our analysis leads to the following orbital elements: K/sub R/=153 km s/sup -1/, K/sub B/=90 km s/sup -1/, P/sub ORB/=0.275129 days. Both K/sub R/ and P/sub ORB/ are significantly different from previously published measurements. We conclude that the white dwarf in SS Cygni may have a mass very near the Chandrasekhar limit.
