IAF inducts indigenous warning system - Netra
- The IAF has formally inducted the first indigenously built Airborne Early Warning and Control System ‘Netra’. DRDO - Center of Airborne Systems (Bengaluru) handed over the first indigenous Airborne Early Warning and Control System (AWACS) to the Indian Air Force (IAF) on 14 February 2017.
- AWACS project developed by the Defence Research and Development Organisation costs a total of Rs 2,400 crore and is capable of detecting in-coming drones, cruise missiles and fighter jets from countries like China and Pakistan.
- These airborne warning systems, capable of long range surveillance, are huge force multipliers.
- AWACS are radars mounted on an aircraft to provide seamless 360-degree coverage of the airspace. Built on an Embraer 145 platform, it can track over 500 targets simultaneously. It acts as a Command base in support for all Air-Defence operations.
Defence Vehicle Interceptor Missile
- DRDO successful test fired of the Prithvi Defence Vehicle (PDV) Interceptor Missile and thus now made India to join a select group of nations having such an effective Ballistic Missile Defence System.
- This is a significant milestone in boosting India’s defence capabilities and will provide enhanced security against ballistic missile threats.
Japanese researchers have successfully gone past 5G data speeds
- Japanese researchers have successfully gone past 5G data speeds to reach speeds that are 10 times faster than 5G Terahertz (THz) Data Transmission.
- A research group of from Hiroshima University has developed a transmitter that achieves 105 gigabits per second throughput between 290 GHz to 315 GHz frequency range. This speed is almost 10 times the speed achieved for the 5G data speed.
ISRO develop TTCP for Spacecraft
- ISRO has indigenously developed Telemetry and Telecommand processor for communication TTCP that was developed by Isro Satellite Centre (Isac) in Bengaluru.
- The TTCP will be first used on the GSAT-19, which will be launched on the first development flight of the indigenously developed GSLV-Mk III-D1.
Arunachal Pradesh to implement e-Cabinet solution
- Arunachal Pradesh on 7 February 2017 became the first state in the northeast to implement e-Cabinet solution for the state cabinet members and therefore the average length of the cabinet meetings will go down from 4-5 hours to just 30-90 minutes
