China launches the rival for the GPS-Beidou

China launches the rival for the GPS-Beidou

China has launched the Beidou Global Positioning Satellite system and has started providing location services for mainland china and nearby territories. China has 10 satellites for this purpose which it started launching in 2003. This system will rival US GPS and reduce china’s dependency on it. This is similar to individual global positioning systems like Galileo by Europe, GLONASS by Russia and IRNSS (Indian Regional Navigational Satellite System) by India. China plans to have 35 total satellites in 2020 which will provide total coverage of the whole world. The chinese system is meant to offer better precision with accuracy of 33feet (10meters) while GPS  offers around 66 feet (20 meters). It will also be able to record speed with 0.2-meter a second accuracy and sync clocks to 0.02 millionths of a second a necessity for guiding missiles and other weapons. So the main purpose of countries rushing for independent satellite systems are not to provide its citizens with a car navigation systems but to have a fool proof system for their defense navigation systems. ...

Why Iran’s capture of US drone is very significant

Iranian TV showed the unmanned “stealth” aircraft apparently undamaged Last week Iranian television showed the captured intact US drone – RQ -170 Sentinel , which it claimed was brought down using electronic warfare where as US insisted that the drone malfunctioned. Iran said it brought down the UAV using electronic ambush ,as the drone violated Iranian airspace by intruding 250Km into its airspace. It also launched a formal complaint to the UN security counsel on US intrusion. America had earlier asked for the return of the drone, to which the Iran has subsequently refused. If Iran had in fact brought  down the drone only using electronic warfare methodologies, then it is something the US has to be worried about. From the footage released by the Iranian television it is clear that the aircraft has sustained only minimal damage adding support to the Iran’s claim of electronic ambush methodology to bring down the drone. If the drone had really malfunctioned like the US claims, the drone would have suffered some significant damage....

Agni-IV launch video, India takes its Ballistic Missile technology to the next level

Agni-IV launch video, India takes its Ballistic Missile technology to the next level

India successfully tested it’s nuclear capable ballistic missile Agni-IV from an island off the odhisa coast. This missile has the range of 3000km  and was developed indigenously after world powers denied missile technology to India. Ring Laser Gyros for Internal Navigation System (RINS) and Micro-Navigation System (MINGS) was developed in Research Centre Imrat (RCI), Hyderabad complemented each other in redundant mode were successfully flown in guidance mode for the first time, said DRDO.   The high performance onboard computer with distributed avionics architecture and high speed reliable communication bus and a full digital control system have controlled and guided the missile to the target with very high level of accuracy.All the radars and electro-optical systems along the coast of Odisha have tracked and monitored all the parameters of the vehicle. No satellites where used during this test and two naval ships located near the target witnessed the final event, the sources said. Watch the Launch video after the jump,...
