India successfully launched PSLV C-23 with 5 satellites

India’s ANTRIX (ISRO’s commercial arm) successfully launched 5 foreign satellites from four countries on board PSLV-C23 rocket which placed them in orbit.

The rocket was launched from Satish Dhawan Space Centre in Sriharikota and was also witnessed by PM Narendra Modi.

ISRO’s Polar Satellite Launch Vehicle PSLV-C23 placed all five satellites into their respective orbits.

The rocket carried with it primary payload of 714 kg French Earth Observation Satellite SPOT-7, 14 kg AISAT of Germany, NLS7.1 (CAN-X4) and NLS7.2 (CAN-X5) of Canada each weighing 15 kg and the 7 kg VELOX-1 of Singapore.

PM Modi extolled the efforts Indian space scientists and asked the space community to develop a SAARC satellite.

He referred to pictures showing rocket components being transported on bicycles.

  • SPOT 7: French satellite, it will be part of the existing Earth observation satellite. It has been built by European space technology company Airbus Defence and Space.
  • AISAT:  German nano-satellite, to focus on the global sea-traffic monitoring system with special emphasis on high traffic zones using AIS signals.
  • NLS 7.1 and NLS 7.2:  Canadian satellite, they will perform Two-spacecraft precision formation flying using differential GPS with centimetre-level relative position and sub-metre level accurate position control system.
  • VELOX-1: Singaporean satellite, it is a technology demonstrator for in-house design of image sensor, MEMS-based attitude determination and control system and inter-satellite RF link.

New Facelock Technology obviates the need to remember complex passwords

Researchers at the University of York in the U.K have developed a new technology named Facelock technology which provides an alternative to remembering complicated passwords.

Retaining complicated passwords has always been a difficult job for most people. There is also a risk of hacking if the passwords are kept too simple.

The new Facelock technology attempts to deal with these issues. It is based on human psychological trait of remembering familiar faces with close to 98% accuracy.

Facelock needs users to choose from a selection of faces that are well known to them. Then when they want to log in or get access to a secure system, a series of face grids is created, and users must select the familiar face in each grid.

As per researchers, it’s easy for users to select a familiar face from the crowd — but very difficult for others to hack, since none of the faces will stand out to them.

Project Android One: Google’s bid to build ultra cheap Smartphones

With a view to build ultra cheap Smartphone, search giant Google launched Project Android One at Google I/O 2014 in San Francisco. Google I/O is Google’s annual developer meeting.

Project Android One is a design reference platform that will enable manufacturers to build ultra-cheap smartphones with much more ease. Google wants to build a Smartphone within Rs. 6000 – 7000 range with a list of recommended apps from Play Auto-installs.

Google will launch the programme from India and it has already tied with Micromax, Karbonn and Spice as initial partners.
