Square kilometer array, or SKA is a new powerful radio telescope that has been developed for better sensitivity, wider dynamic range, wider field of view, and other parameters that may not be considered. According to PN Wilkinson, KI's astronomy Kellermann, R. D. Ekers, J. M. Cordes and T. Joseph W. Lazio (2004). Since SKA can provide explanation and evidence of phenomena such as space network, transcendental hypothesis, gas forming galaxy, semi analytical model, etc., it is closely related to the understanding of the universe.
Known as the square kiln array (SKA), it explores the universe, identifies potential external threats to our planet, and answers some of the astronomer's basic questions I hope. Thousands of receptors are about 1 kilometer apart and connect the whole continent. Please read a higher 6 feet of aluminum, 500 lbs high, this is not your ordinary teddy bear.

GMRT is an array of 30 parabolic antennas (disks) dispersed in 25 kilometer region. In 30 square kilometers, 12 dishes are centered in a random way of 1 square kilometer, 18 dishes are spread along three arms of a Y-shaped arrangement, and the length of each arm is about 14 kilometers. The position of GMRT as SKA detector of the world's largest telescope project will be completed in 2024. As part of this, GMRT is undergoing major scientific and technical upgrades to improve its sensitivity. Most upgrade work is synchronized with the SKA project team. GMRT provides valuable feedback to the team that designs SKA. resource
