Ofeq-7

Ofeq-7 belongs to the Ofeq series, a line of indigenously manufactured Israeli imaging satellites.[4] The program is overseen by the Defense Ministry's Space and Satellite Administration, an agency established in 1981 that led eleven successful Ofeq-series launches beginning with Israel's first Ofeq launch in 1988.[5]

Israel Aerospace Industries developed and manufactured the Ofeq satellites.[1] The Ofeq program used the Israeli-built Shavit launcher.[3] The Ofeq series uses an east-to-west orbit at approximately 600 kilometers altitude, a configuration intended to provide optimal daylight coverage of the Middle East.[1]

The satellites were designed to function as a constellation so that a surveilled area would not be left unwatched, enabling the Israel Defense Forces to use them as tactical tools during operations as well as for strategic intelligence gathering.[1] By 2009, Ofeq-5 and Ofeq-7 were both listed as deployed reconnaissance satellites; Ofeq-7 was also reported as operating alongside TecSAR.[4][1]

Israel preferred to launch its Ofeq-series surveillance satellites independently using Shavit rather than relying on foreign participation.[3] This approach had a strategic rationale: independent launch capability could remain available during a crisis or embargo when foreign assistance might not be.[3] A practical constraint shaped launches from Israeli territory: they had to be directed westward over the sea to prevent launcher stages, or a malfunctioning satellite, from falling on populated areas or foreign territory. Flying against Earth's rotation restricted achievable orbits and reduced the payload weight Shavit could carry.[3]

The program suffered a notable setback when Ofeq-6 failed to reach orbit in October 2004 and fell into the sea.[2] Engineers fully studied the design fault behind that failure and incorporated its lessons into Ofeq-7 after extensive testing.[2] The successful launch was consequently described as particularly significant.[2]

Ofeq-7 lifted off from Palmahim Base at 2:40 a.m. on a Monday morning in June 2007.[2] The satellite entered orbit, and Israel expected to receive its first images within 48 to 72 hours while engineers conducted comprehensive system tests.[2]

Its reported components included a GPS system, central computer, gas tank, and telescope.[2] The satellite was expected to complete one orbit around Earth every 90 minutes and to remain in orbit for four to six years.[2] Brigadier General Dr. Kobi Bortman, head of the Air Force's equipment squadron, said Ofeq-7 incorporated the project's best available technology, was better than Ofeq-5, and should provide improved images; the program aimed to receive images for at least four years.[2]

The launch of Ofeq-7 in June 2007 augmented the Israeli intelligence community and placed the satellite alongside Eros-B and TecSAR within Israel's growing space-based surveillance capability.[4][3] A senior security source said at the time that the satellite was intended to improve intelligence, particularly concerning Iran, and that its capabilities, combined with those of satellites already in orbit, would significantly improve Israel's operational and intelligence capabilities.[2]

TecSAR, launched in January 2008 using an Indian Polar Satellite Launch Vehicle, added radar imaging that enabled day-and-night, all-weather coverage and complemented Ofeq-7.[3] Together, the satellites increased the frequency and range of Israel's overhead reconnaissance coverage in the Middle East.[3]

Published sources differ on Ofeq-7's relationship to Ofeq-5. The 2009 INSS Strategic Survey described Ofeq-7 as replacing the outdated Ofeq-5, while a separate INSS reference table listed both as deployed reconnaissance satellites.[6][4] The available sources do not reconcile those descriptions.
