DARPA developing On-demand Satellite Imaging for Soldiers

DARPA - Today, the lowest echelon members of the U.S. military deployed in remote overseas locations are unable to obtain on-demand satellite imagery in a timely and persistent manner for pre-mission planning. This is due to lack of satellite overflight opportunities, inability to receive direct satellite downlinks at the tactical level and information flow restrictions.

DARPA’s SeeMe program (Space Enabled Effects for Military Engagements) aims to give mobile individual US warfighters access to on-demand, space-based tactical information in remote and beyond- line-of-sight conditions. If successful, SeeMe will provide small squads and individual teams the ability to receive timely imagery of their specific overseas location directly from a small satellite with the press of a button — something that’s currently not possible from military or commercial satellites.





“We envision a constellation of small satellites, at a fraction of the cost of airborne systems, that would allow deployed warfighters overseas to hit ‘see me’ on existing handheld devices and in less than 90 minutes receive a satellite image of their precise location to aid in mission planning,” said Dave Barnhart, DARPA program manager. “To create inexpensive, easily manufacturable small satellites costing $500K apiece will require leveraging existing non-traditional aerospace off-the-shelf technologies for rapid manufacturing, such as the mobile phone industry’s original design manufacturers, as well as developing advanced technologies for optics, power, propulsion and communications to keep size and weight down.”

The SeeMe constellation may consist of some two-dozen satellites, each lasting 60-90 days in a very low-earth orbit before de-orbiting and completely burning up, leaving no space debris and causing no re-entry hazard. The program may leverage DARPA’s Airborne Launch Assist Space Access (ALASA) program, which is developing an aircraft-based satellite launch platform for payloads on the order of 100 lbs. ALASA seeks to provide low-cost, rapid launch of small satellites into any required orbit, a capability not possible today from fixed ground launch sites.

“SeeMe is a logical adjunct to UAV technology, which will continue to provide local or regional very high-resolution coverage, but which can’t cover extended areas without frequent refueling,” Barnhart said. “With a SeeMe constellation, we hope to directly support warfighters in multiple deployed overseas locations simultaneously with no logistics or maintenance costs beyond the warfighters’ handhelds.”
