In short

The Indian Space Research Organization (ISRO) is launching two pioneering scientific spacecraft this year, one to study the Sun, and the other to land on the moon – the nation’s first landing on a celestial body.

ESA’s deep communication antennas will provide critical support to the two missionaries at each level of the route, locating the aircraft, navigating their locations to critical levels, dispatching to orders and access to telemetry and economic science.


From Sri Lanka to the Himalayas

In June 2021, ESA and the Indian Space Research Organization (ISRO) signed an agreement to provide technical support to each other, including serving and communicating with future Indian space missionaries. measurement through ESA’s bases.

The first missions to benefit from this new support agreement will allow India to observe the Sun and moon with the Aditya-L1 solar observatory and Chandrayaan-3 lunar lander and rover, both for launch in 2022 from the Satish Dhawan Space Center at Sriharikota Famous (SDSC SHAR), India.

“Talking about the deep space of each air missionary is an important part,” said Ramesh Chellathurai, ESA Director and ESA Director for ISRO. “Airports are keeping a close eye on the earth as they search for objects and weather problems. Without the support of the base, data cannot be retrieved from them. an airplane, to know how it works, to see if it is safe or to know where it is.

A place in the Sun.

The tower was named Aditya-L1 after the Hindu Sun god. Aditya, and the home of the next spacecraft, L1 – the first Lagrange point of the Earth -Sun system. He will learn some properties of the Sun, such as the dynamics and cause of coronal mass ejections.

Her home on L1 allows Aditya to orbit the Sun at a perpetual distance from Earth, but the Earth does not cover her vision of our star.

“The plane will always be on the same path from Earth to the Sun,” Ramesh said. “Therefore, when searching the Earth, no single site will always detect Aditya-L1. Using a global database such as ESA is the best way to exchange data and data. order with this aircraft as soon as possible. ”

ESA is one of the only agencies in the world with a network of deep -seated sites located in the world. The Estrack system can track and communicate with aircraft at any time or in any direction, up to two billion kilometers from Earth.

ESA New Norcia’s deep space tourism

The 35-meter-deep Estrack antennas, located in New Norcia, Australia, Malargüe, Argentina, and Cebreros, Spain, will all support the Aditya-L1. Additional support will be provided by ESA’s 15-meter antenna at the European airport in Kourou, French Guiana, and a 32-meter deep space antenna at Goonhilly airport in the UK.

The combination of ESA and Goonhilly antennas will provide support, telemetry and command (TT&C) for the Aditya-L1, with ISRO’s deep-sea antennas in India providing new communication time.

The data and telemetry sent by Aditya-L1 arriving through one of the bases will be sent to ESA’s ESOC mission control center in Darmstadt, Germany. From there, they will be sent to ISRO’s ISTRAC workshop for inspection.

ESA’s involvement with the missionary first began. The ISRO flight team tested the software they use to accurately determine the location and orbit of Aditya-L1 at ESA’s Gaia observatory. ESA’s flight simulation engineers have used their years of experience in flying aircraft across the Solar System to validate this program by comparing ISRO’s results to their own measurements. .

However, radio frequency compatibility testing is important to ensure that the device used by the two companies can work together by December 2021.

Support for Aditya -L1 was immediately extended to ISRO’s upcoming Chandrayaan -3 – “Moon craft” – mission to study the moon’s surface in the southern pole of the moon.

The missionary is on an island with a rover, spending two weeks leading science and technology projects on the skin. Chandrayaan -3 is India’s first level in any other celestial body – it is an important element for any celestial body.

ESA’s Kourou antenna and the Goonhilly base will be connected to NASA’s deep-sea spacecraft supporting the mission and providing the same support to Chandrayaan-3 as Aditya-L1.

ESA central support for Aditya L1 and Chandrayaan-3 begins with the critical start and first orbit phase and continues to the end of the two missions, if required by ISRO.

India and the sky

ISRO was founded in 1969 and is headquartered in Bengaluru. It employs a start -up base and a deep ground base in India.

The Organization was one of ESA’s first global partners in 1970, first participating in the supply of ESA equipment for ISRO’s Chandrayaan-1 lunar orbiter mission, established in 2008.
