Working Group C

Bridging Together Ground and Space Capabilities for Users and Operators


Monday – February 27, 2023
9:00 AM-11:30 AM PT


This working group looks to bridge the gap between space and ground capabilities for various users and operators, especially system customers. Specifically, this working group aims to identify the most pressing challenges facing integration of these types of capabilities. These capabilities range from basic low-bandwidth communications to moving massive amounts of data from observation satellites, typically high-bandwidth video and imagery. Position, navigation, and timing (PNT) capabilities, such as GPS’s Wide Area Augmentation System (WAAS), increasingly fuse together both space and ground based signals.

Various efforts to help bridge this gap are prevalent throughout civil, commercial, and national security space. For civil space, NASA has developed the Near Space Network (NSN), bridging together ground stations, low earth orbit, and deep space. An increasingly common example in the commercial space sector include cellular signals, broadcast from both satellites and ground, received from the same personal device (tablet or phone). On the national security space front, efforts such at the US Air Force’s Advanced Battle Management System (ABMS) and US Space Force’s meshONE-Terrestrial (meshONE-T) attempt to bridge the gap in moving massive amounts of data especially for warfighters in an increasingly mobile tactical environment.

Working group attendees will share their past experiences and thoughts through a whiteboarding and breakout session. A near-term strategic action plan to bridging this gap will also be developed during this session. We anticipate that these attendees will be representative of a cross-section of both ground and space system entities throughout the civil, commercial, and national security space sectors.
