What’s new: Interesting insight to a Space Force study about future space-based PNT for the military.
Why it’s important: It seems to give some interesting hints about DoD’s thinking and potential plans.
What else to know:
- The study abstract discusses leveraging existing commercial Space Data Networks (SDN) for military PNT
- We wonder if, since the defense establishment has ceased its own LEO PNT efforts, if it might be contemplating purchasing a LEO PNT system outright or establishing long term contracts with one or more providers.
- This is a Space Force effort, so everything under consideration is space-based.
- We wonder if anyone is looking at the department’s overall future PNT architecture and incorporating any terrestrial broadcast and/or autonomous systems like magnetic sensing and quantum.
