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.
