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.
