HAIFA, Israel-Satellite designers at Israel Aerospace Industries Ltd. (IAI) at Ben Gurion International Airport, Israel, needed a space camera for the OPTSAT 3000 observation satellite they are building for the Italian government. They found their solution at Elbit Systems Electro-Optics (Elop) in Haifa, Israel.

IAI is awarding a roughly $40 million contract to Elop that involves the Jupiter advanced camera and additional services. Work on the contract should be finished within three and a half years, Elop officials say.
The IAI OPTSAT 3000 three-axis stabilized, autonomous satellite is designed under a low-weight, low-power, high-reliability concept to deliver a high geolocation accuracy and impressive weight-to-performance ratio. The satellite offers high resolution, high geolocation accuracy, simultaneous panchromatic and multi-spectral imaging capability, high image quality, and a weight of 400 kilograms that enables a wide range of launching options.
The low weight and compact dimensions of the satellite also result in low inertia for agility to take many images, widely spread in one satellite pass.
The IAI OPTSAT is designed for a mission life of more than six years, and is based on the IMPS II bus.

Raytheon to help develop small-satellite technology for front-line situational awareness
BY John Keller
ARLINGTON, Va.-Reconnaissance and surveillance experts at Raytheon Co. Missile Systems in Tucson, Ariz., are helping a U.S. military effort to provide useful, persistent-surveillance imagery on demand to the lowest-echelon warfighter in the field from small low-cost satellites.
Raytheon received a $949,679 contract from the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., for the Space Enabled Effects for Military Engagements (SeeMe) program.
SeeMe will develop enabling technologies that eventually could help make relevant battlefield imagery available to front-line warfight- ers in real time using constellations of temporary and inexpensive orbiting satellites that are launched quickly enough to support fast-moving military operations.
Future SeeMe satellites could fill gaps in battlefield situational awareness before, during, and after military engagements, DARPA officials say.
The SeeMe program is expected to yield technology that could provide reliable persistent-surveillance data to front-line forces using small, short-lived, very-low-cost satellites operating at low altitudes that are networked to fielded military communications systems and handheld devices.
For the SeeMe program, Raytheon engineers will try to find ways to build satellites that cost no more than $500,000 each, not counting launch and ground-support operations. Other contractors in addition to Raytheon most likely will become involved in the SeeMe program.
Ultimately, small satellites developed with SeeMe program technology should receive support from the DARPA Airborne Launch Assist Space Access (ALASA) program, which is trying to develop the ability to launch a 100-pound satellite for a total cost of less than $1 million, which is about one-third of today's satellite launch costs.
DARPA awarded five ALASA research contracts in 2012 to Space Information Laboratories LLC in Santa Maria, Calif.; Ventions LLC in San Francisco; the Boeing Co. in Huntington Beach, Calif.; Northrop Grumman Corp. in El Segundo, Calif.; and Lockheed Martin Corp. in Palmdale, Calif.
The SeeMe short-duration satellite constellations would compensate for today's weaknesses in gathering situational-awareness data that currently does not provide the lowest-echelon warfighters with on-demand satellite imagery due to priority conflicts, classification restrictions, and a lack of satellite overflight opportunities and information distribution channels.
At the same time, terrorists and other enemy forces have access to commercial imagery information that gives them an advantage. The SeeMe program would give small U.S. squads and fire-teams reliable information in remote and beyond-line-of-sight conditions, DARPA officials say.
Rather than using expensive high-orbit reconnaissance satellites that are tasked remotely and their products analyzed through a centralized organization, the SeeMe program would use short-lived, low-cost satellites to large global coverage at lower cost than a set of unmanned aerial vehicles (UAVs) flying simultaneously over several theaters per day, officials say.
SeeMe satellites would be designed based on cost, rather than on performance, and would seek to revolutionize the existing satellite-development model to cut costs to a fraction of manned or unmanned aircraft-primarily using commercial off-the-shelf (COTS) components.
SeeMe satellites also would use non-traditional RF and optical apertures and imagery processing techniques, as well as innovative manufacturing and rapid launch systems to match the speed of military operations.
The combined SeeMe and ALASA programs will culminate in an on-orbit demonstration in 2014 or 2015 of a constellation of 24 SeeMe satellites operating in low orbits between 125 and 185 miles above the Earth.
The program seeks to deliver a constellation of small reconnaissance satellites within 90 days of order at a cost of about $12 million-a fraction of the cost of an existing UAV. SeeMe satellites would provide persistent coverage of any point on the Earth with no coverage gaps greater than 90 minutes, and would last for at least 45 days.
The preliminary phase of the SeeMe program is to last for 14 months, while the second phase of the program would span 15 months and demonstrate a production run of at least six satellites. The third phase would last a year and produce a constellation of 24 satellites.
