This is old news from 2008, but, surprisingly, there's very little found about it on the net.
DARPA Gives Go Ahead to Underground SatNav
Homeland Security Today
Defense Advanced Research Projects Agency (DARPA) gave the ok to Failure Analysis to build the Defense Underground Mapping Satellite Tracking and
Ranging (DUMSTR) system. The company proposed $100,000,000.00/year proposal to the National Reconnaissance Office (NRO) in February, 2008. The project
is a a low-earth-orbiting, satellite-based, underground mapping matrix that will use existing Air Force satellite technology from the Defense Mapping
Satellite Program (DMSP) and the Global Positioning System (GPS). The technology will allow the mapping of underground civil and military facilities
around the world and “provide geological science information for plate tectonics, underground volcano structure and growth of lava chambers
promising to increase the likelihood of future earthquake prediction capability.”
Thus, we have the Defense Underground Mapping Satellite Tracking and Ranging (DUMSTR) system.
It was green lit back in 2008. I wonder where it is in developmental or deployment staging now.
Some further Information:
DUMSTR consists of a matrix of 100, 3-axis controlled satellites to provide 2-D and 3-D underground topology to a depth of over 5,000 ft. Failure
Analysis is experienced with satellite constellations such as GLOBALSTAR, GPS, INTELSAT and DMSP. “As international military and civil facilities
are being located deeper and deeper underground to improve their survivability, the U.S. military wanted a system to identify them”, said Dr. Len
Losik, President of Failure Analysis. DUMSTR was developed from telemetry prognostic signal intelligence technology developed and used on Air Force
GPS 28 satellite constellation of satellites. Telemetry prognostics stops satellite infant mortality failures in the first year of in-orbit satellite
operations and launch failures.
Details tout resolution down to and over 5000 ft. That's around one mile depth underground!
If, then, anyone has an underground base that isn't well over one mile underground, this satellite system should be able to map it out in all its
super secret glory.
Noting the civil engineering aspect listed, it might very well be feasible for laymen and conspiracy theorists to get their hands on some underground
maps on submitting requests through the proper channels.
What this could mean for non-military interests, including Conspiracy Theory types:
1. Put the question of magical mythical secret Alien bases under Dulce, mystical ancient underground cities like Kinkaid's cave, NAZI secret bunkers
under Antarctica, or even tunnels leading into Hollow Earth to rest once and for all.
2. Archaeology! Hunting for lost and buried Pyramids or temples and cities beneath the sands of Egypt? That spooky giant pyramid supposedly buried
in Alaska? Looking for the foundation stones to the lost city of Atlantis? There's now no need to travel and muck about in the dirt until
confirmation is had. Target your location and get it imaged.
3. Additionally, from a geological standpoint, Doom Porn enthusiasts could get updated 3-D underground maps of major fault lines, and even accurate
models of magma chambers like the one below Yellowstone.
I've no information on what channels one would need go through to obtain maps. Nor is there any confirmation on the working status of this project.
That, however, is something, perhaps, the ATS community might look into?
