Progress on the evaluation of systematic frequency shifts is described in the development of the optical frequency standard based on single-trapped {sup 40}Ca{sup +} with a ''clock'' transition at 729 nm. The overall systematic uncertainty of the 4s {sup 2} S{sub 1/2}-3d {sup 2} D{sub 5/2} clock resonance has been characterized to be 7.8 x 10{sup -16}. This uncertainty is at a level similar to the Cs fountain primary standard, while the potential stability for the {sup 40}Ca{sup +} clock exceeds that of Cs.
