DARPA this week put out a request for submissions to build a new network of low-orbit satellites to enable near real-time satellite images enabling active ground troops to plan military missions directly from the field.
The program, the Space Enabled Effects for Military Engagements -- dubbed SeeMe -- aims to give individual fighters the ability to immediately call on low-cost satellites for up-to-the minute visual information.
Moving away from the slow, expensive, bulky, and complicated current satellite systems, DARPA envisions a swarm of small, easily deployable, and disposable satellites which will use non-aerospace hardware and manufacturing techniques to provide quick and cheap visual information anywhere on the ground -- for less than $500,000 each.
Currently, individual ground troops in remote locations are unable to obtain on-demand satellite imagery in a timely manner during missions. Lack of satellite overflight opportunities, delays due to current satellite mobility, and the inability of individual ground troops to to receive direct satellite information, are hindering military operational capabilities, says DARPA.
The SeeMe program seeks to offer nearly real-time tactical information directly to troops, giving them critical planning information for specific locations requests within minutes.
Launched from airplanes, the very low-Earth orbit satellites aim to provide more extensive coverage than current eye-in-the-sky systems. DARPA says SeeMe needs to "address a change in the satellite build model from 'performance centric' to 'cost centric'" by relying on non-aerospace vendors -- even conforming to internationally accepted commercial packaging, transport, and storage methods, such as FedEx, for logistical ease.
As satellite cost goes down, DARPA says, the constellation size increases, and information delay request times due to satellite overpass and travel-time decrease.
The small, missile-like launch vehicles will be deployed from planes into low-Earth orbit at an altitude of around 1,000 to 2,000 kilometers. DARPA says the initial SeeMe satellite cost goal is less than $500,000, a fraction of traditional satellites, which cost millions of dollars to manufacture, and millions more to launch.
Once the missile reaches orbit, the disposable satellites would deploy with non-aerospace components such as solid state, embedded control CMOS optics, lowering the fixed costs, and start providing coverage in as little as 90 minutes.
Troops on the ground will be able to directly contact the satellites to request information directly to their devices.
Swarms of the SeeMe satellites will deliver information to troops at a fraction of the cost of current airborne UAV systems. The proposals detail satellites each lasting 60 to 90 days, which will completely burn up in the atmosphere when no longer needed.
The program envisions swarms of satellites at a fraction of the cost of airborne systems, sending information to existing handheld devices, such as iPhones, to receive a satellite images of their precise location within 90 minutes.
One goal states capability for "'tablet' sized images, downlinked within 90 minute revisit time. Capable to respond to about 10 users requests simultaneously."
DARPA says rapid, low-cost manufacturing technologies from the mobile phone industry, propulsion technology from the automobile racing industry, solid state components from electronics manufacturers, valve technology from the medical pneumatic industry, and advanced optics, might all play a part in the next generation of battlefield planning and logistics.
“With a SeeMe constellation," says DARPA program manager Dave Barnhart, "we hope to directly support warfighters in multiple deployed overseas locations simultaneously with no logistics or maintenance costs beyond the warfighters’ handhelds.”
