Ofeq, also spelled Offek or Ofek (Hebrew: אופק, lit. Horizon) is the designation of a series of Israeli reconnaissance satellites. All Ofeq satellites have been launched on Shavit rockets from Palmachim Air Force Base on the Mediterranean coast into a Low Earth Orbit, completing one earth orbit every 90 minutes. The satellite launches caused Israel to become the eighth nation to launch satellites. Both the satellites and the launchers were designed and manufactured by Israel Aircraft Industries (IAI).

Description
While exact technical details and capabilities are classified, it is assumed that the Ofeq satellites have ultraviolet and visible imaging sensors, and an effective operational lifespan of 1-3 years. While some early reports state the reconnaissance capabilities as such that would allow "reading license plates in Baghdad", other reports place the imaging resolution at 6 ft (1.8 meters). Location of Baghdad within Iraq Baghdad (Arabic: , Persian: بغداد (Meaning in Persian : from angels) is the capital of Iraq and of Baghdad Province. ...
Most non-Israeli satellites are launched eastward to gain a boost from the Earth's rotational speed. However, Ofeq satellites are launched westward (retrograde orbit) over the Mediterranean to avoid flying and dropping spent rocket stages over populated areas in Israel and neighboring Arab countries. Other Israeli satellites (such as the Amos series) are launched from locations in other countries. This article is about retrograde motion. ...

Ofeq's east-to-west orbit at 36 degrees inclination is phased to give optimal daylight coverage of the Middle East. Ofeq makes a half-dozen or so daylight passes per day over Israel and the surrounding countries, whereas US and Russian spysats only get one or two passes per day from their higher inclination orbits. This optimal coverage degrades after several months, nevertheless keeping a very good coverage of the Middle East.

Launch history - Ofeq 1, launched September 19, 1988, possessed a weight of 155 kg and circled the earth on an orbit with a perigee of 249 km and an apogee of 1149 km on a course bent around 142.9 degrees. It accomplished mainly solar cell and radio transmission tests.
- Ofeq 2, was launched April 23, 1990 on a course with a perigee of 149 km and an apogee of 251 km, bent around 143.2 degrees. It also accomplished communication tests.
- Another satellite of the Ofeq series, possibly attempted to be launched on September 15, 1994, was possibly aborted or had a failure during launch.
- Ofeq 3, launched April 5, 1995, was the first operational Israeli satellite with reconnaissance (photography) capabilities. It weighed 225 kg and had a perigee of 369 km and was launched on a new version of Shavit.
- Ofeq 4, launched January 22, 1998, did not achieve earth orbit due to a launcher failure and was lost.
- Ofeq 5, was launched 28 May 2002. The 300 kg Ofeq 5 orbited the earth on a course with a perigee of 262 km and an apogee of 774 km, bent around 143.5 degrees. During the course of its mission, its perigee was raised to 369 km and its apogee was lowered on 771 kilometers, in an attempt to prolong the satellite's lifespan.
- Ofeq 6, launched September 6, 2004 encountered another launcher failure, failed to achieve low earth orbit and also crashed to the sea. The launcher failure was due to a new third stage of the Shavit launcher (all launchers until then used two stages only).
