Abstract: Abstract Aiming at the security requirement of command information system and domestic platform, the aerospace command decision-making platform was built under the independent and controllable condition based on do- mestic GIS software. Using the method of path optimization selection by integrating the path planning and the national road network model, the plotting work about coordination service of multiple seat and multiple role was solved, and based on SGP4 orbit and investigation scope calculation model, transit forecast of satellite was realized. The platform has the function of optimization path selection, coordination plotting work, satellite investigation scope and multi-mode situation display. Thus the platform can provide the valuable analytical data and task information for the decision of commanders.
