The determination of the orbital parameters of binaries is an important constituent of fundamental astronomy. It can provide orbital parameters of component stars, which are necessary for a high-precision and dense catalog of stars. Also, it is the only reliable way of determining stellar masses, a crucial parameter for many astronomical researches. A large amount of high precision data about binaries has accumulated, and it is increasing rapidly these days. As a result, the determination of the orbital parameters of binaries is now a hot joint topic between astrometry and celestial mechanics. Historical background is briefly introduced, and recent progress is reviewed, including various kinds of observational data, theoretical models, fitting methods, and published and on-line results. Future perspective is also presented.
