Inertial navigation system is a computerized mechanism that uses changes in the object՚s own position coupled with GPS, which is satellite based.
Passive homing head for guidance is a system that can detect, classify, and engage targets (radio frequency sources in this case) over a wide band of frequencies as programmed.
Rudram-1 is an air-to-surface missile, designed and developed by the DRDO.
DRDO conducted a successful test of the New Generation Anti-Radiation Missile (NGRAM) also called the Rudram-1 at the Integrated Test Range (ITR) in Balasore (Odisha) .
Rudram-1 is the first indigenous anti-radiation missile of the country.
Once the missile locks on the target, it can strike accurately even if the radiation source switches off in between.
The missile, integrated with SU-30 MkI aircraft, has the capability of varying ranges based on the launch conditions.
It can be adapted for launch from other fighter jets too.
It can be launched from altitudes of 500 m to 15 km and speeds of 0.6 to 2 Mach.
Rudram has been developed for the Indian Air Force requirement to enhance its Suppression of Enemy Air Defense (SEAD) capability.
Further, modern day warfare is more network centric, which means it comprises elaborate detection, surveillance and communication systems that are integrated with the weapons systems.
This is yet another test of indigenously developed weapons systems in addition to the recent tests of Shaurya missile or Hypersonic Technology Demonstrator Vehicle (HSTDV) , which is an unmanned scramjet vehicle, or the test flight of a Supersonic Missile Assisted Release of Torpedo (SMART) system.
