Galactic Positioning System


The GPS works so well for cars, ships and even planes, but have you ever wondered how the Sci-Fi space ships find their way in galaxy?? Yeah GPS, help them too, not the Global Positioning System but the Galactic Positioning System which is now under development. NASA’s new autonomous X-ray navigation system could provide deep-space missions with a cosmic version of GPS.  Instead of satellite signals, they use X rays from pulsars.  Pulsars are a type of dead star having enormous magnetic fields, whose rotation produces X-ray signals with an highly exact rhythm. Pulsars are called “cosmic lighthouses” because their rapid pulse of radio emission is so predictable, that it can be used as a simple straightforward method of Navigation. The system works by combining pulsar pulse data from a reference location such as Earth allowing spaceships to determine their location in space to an accuracy of 3 miles.

All eyes to ISRO…….. ISRO ROCKS AGAIN….

The PSLV-C37 blasting off from the Satish Dhawan Space Centre in Sriharikota

India is all set to rule the space… Heard right?? With its mega-launch program on February 15, India will create history by launching a record 104 satellites, including 101 foreign ones, into the polar sun-synchronous orbit(SSO), about 500 km above the earth. The launch is expected to be a world record when it comes to the number of satellites put into orbit by a launch vehicle in a single mission, surpassing the 37 satellites launch record set by a Russian rocket on June 19, 2014.
