Gravitational field data processing involves in many aspects and related processing softwares. This paper applied software SPACASPS self-developed in 11th Five-Year period of the province to processing of gravitational field data on known ore district, such as reduction of curved surface into a horizontal plane, downward continuation, separation of local field from background field. These three key technologies proved good in application result.
