The invention discloses a space target orbit determination method and system based on multi-data source fusion. The method comprises the steps that a TLE file of a space target at the latest moment is acquired; making an observation plan, performing optical angle measurement on the space target, and performing radar distance measurement on the space target through a radar system; based on the angle measurement data and the relative distance, carrying out initial orbit determination on the space target by utilizing a Good algorithm; taking the initial orbit result as an input parameter of a precise orbit, determining a condition equation of precise orbit determination, and solving to obtain a precise orbit determination result; and generating a space target new calendar table according to the precise orbit determination result. The satellite relative distance is provided based on a radar ranging system, multi-data-source combined orbit determination including initial orbit determination and precise orbit determination is carried out on a space target, an initial orbit determination result is obtained based on data fusing optical angle measurement and the radar relative distance, the precise orbit determination takes the initial orbit determination result as an input parameter, the process is simplified, and the orbit determination precision is improved. And the orbit determination precision requirement of the space target can be met.
