The stealth capability of BrahMos enhanced by terrain contour matching system (TERCOM) and Digital Area Scene Matching and Area Co-relation system allow its high maneuverability as well as pinpoint accuracy.
The Granat has a range of 3,000 km with a CEP (Circular Error of Probability) of 150 metres and its inertial navigation system is complemented by Tercom guidance using a radar altimeter.
The missile also incorporates the most modern cruise missile technology of Terrain Contour Matching (TERCOM) and Digital Scene Matching and Area Co-relation (DSMAC), which enhances its precision and effectiveness manifolds.
Hatf-VII also incorpo-rates modern cruise missile technol-ogy such as Terrain Contour Match-ing (TERCOM) and Digital Scene Matching and Area Co-relation (DSMAC), according to Pakistan ilitary spokesman Major General Athar Abbas.
It said that the missile "carry strategic and conventional warheads, has stealth capabilities, is a low flying, terrain hugging missile with high maneuverability, pin point accuracy and radar avoidance features." It also incorporates the modern cruise missile technology of Terrain Contour Matching (TERCOM) and Digital Scene Matching and Area Co-relation (DSMAC), added the statement.

Summary: The Association for Lebanese Organic Agriculture (ALOA) held a conference on organic crops in Lebanon in Sin al-Fil on Thursday, partnering with UCODEP, TerCom, the Mediterranean Agronomic Institute of Bari (MAI Bari) and a collection of European NGOs in an effort to integrate institutional and community organic policies.
The navigation system consists of an inertial-navigation unit, GPS receiver, TERCOM (terrainaltitude/barometric-altitude comparison), and a Raytheon imaging-infrared digital camera.
In the midcourse phase, a radar-based terrain contour matching (TERCOM) system and/or satellite navigation system such as GPS or GLONASS correct for the inherent inaccuracies of the INS.
Building on the success of the first demonstration flight test August 23, the missile also successfully demonstrated GPS jamming perfo rmance, Terrain Contour Matching (TERCOM) processing and time of arrival performance.
Since TERCOM works only over hilly terrain, it is supplemented by systems that compare stored terrain images with images taken en route.
Tomahawks navigated by terrain-contour matching (Tercom) with digital scene-matching area correlation (Dsmac) in the terminal phase, while the Calcms used less accurate GPS/INS.
