Automated Service Agreements for Ground Station Scheduling Objective Develop and demonstrate autonomously scheduling or ground station assets owned and operated by third parties. Enable real-time access to space-based assets. Transfer technology to Aerospace and Networking community The techniques can be extended to space- based assets and between space-based assets.. Approach General Dynamics and SSTL have developed some machine-to-machine scheduling using GD’s VMOC and SSTL’s Mission Planning System GRC will develop a contract vehicle to have the existing Virtual Mission Operations Center developed by GD implement automated scheduling of Universal Space Networks’ ground assets in order to perform automated commanding of a space asset.
