The ISRO lost contact with the Vikram lander used in Chandrayaan 2 at around 1: 52 minutes of the night. ISRO uses IDSN (Indian Deep Space Network) to maintain contact with Chandrayaan 2‘s Vikram Lander and Orbiter. Right now ISRO is in contact with the orbiter orbiting the outer orbit of the moon with the help of this network technology. With this network technology ISRO exchanges data with orbiter and Vikram Lander. A robotic vehicle moving on the lunar surface, called the Pragyan Rover, does not use this technique. The Pragyan Rover can only communicate with low-frequency networks with Vikram Lander. This is the reason that after the ISRO scientists lost contact with Vikram Lander, the exact location of the Pragyan Rover could not be known.
What is IDSN?
IDSN is a communication technology that is used to communicate with satellites sent to ISRO space. A very large network antenna has been used to establish this network which is capable of sending high-frequency radio signals. The hub of this IDSN network of ISRO is located in Bylalu, Bengaluru, capital of Karnataka. It was established on 17 October 2008. This antenna has been designed by Hyderabad State Electronic Corporation of India Limited. A total of Rs 65 crore has been spent to set up this antenna. Similar to ISRO’s IDSN network, the US, China, Russia, Europe and Japan carry out their space programs.
ISRO uses ISRO Telemetry, Tracking and Command Network (ISTRAC) to send signals to space. It consists of three antennas, one 18m (59ft), one 32m (105ft) and one 11m antenna. The IDSN transmits signals through the baseband system. Its largest 32-meter entry wheel and the track is built on the basis of design. It is capable of uplinking both S-band and X band.
This 32-meter antenna was used for the operation of Chandrayaan 1. Apart from this, the 18-meter antenna is known as a deep-space antenna. At the same time, the third antenna is 11 meters, which is used as a terminal antenna. These antennas have been used to communicate with Chandrayaan 1, Chandrayaan 2 and Mangalyaan.
