Last week I wrote about GPS and how there is a probability that other nations could jam or spoof the GPS constellation due to the fact the GPS satellite design information is publicly available, allowing threat actors to easily complete the Reconnaissance step in their attack. Also, the majority of nation’s navigational satellites have very similar RF link parameters. This vulnerability to a highly critical satellite constellation is being addressed by developing back up constellations to increase the capabilities resiliency. This resiliency is being realized through program named, R-GPS (Resilient-Global Positioning System). While the Space Force program’s name is on the nose, the intent allows security stance of GPS satellite constellation to add another layer of depth. Four companies will develop competing design with a goal to launch the 8 initial satellites in 2028.
The space news article states ‘Air Force Secretary Frank Kendall has designated R-GPS as a high-priority initiative, citing growing electronic and cyber threats to the current GPS infrastructure. The new satellites will broadcast military M-Code signals as well as standard GPS frequencies.’ 1.
This program is a great indication that the DOD is putting their money where there mouth is with regards to protecting critical space assets from cyber threats. It will be interesting to see this program mature and how much the government will share about the new fleet of satellites. The design concepts are set to be completed in the next 6 to 8 months.
