India's Indigenously Developed Multi-Object Tracking Radar for Space Applications Nears Completion

[Chanakya's_Chant]

Indigenous radar to be ready soon

The totally indigenous Rs. 240-crore multi-object tracking radar, which was developed and built by scientists of the Indian Space Research Organisation (ISRO) and some industries of the country, will be ready for operation during the first quarter of 2015.

“The electronics, mechanical structure and radom of the radar are ready and integration of all components will start during the month-end. This is the first totally indigenous multi-object tracking radar,” SHAR-ISRO Associate Director and Project Director of the radar V. Seshagiri Rao said here on Monday.

“The new radar which will operate from Sriharikota range can track nearly 10 objects simultaneously in a distance as far as 1000 km in space, while the conventional radars spot a single object at a time. This is useful in many ways since it can detect 10 objects at a time and in case space debris is approaching an Indian satellite, the path of satellite can be diverted to avoid collision and damage,” Mr. Seshagiri Rao explained about the radar while talking to The Hindu.

“Antenna of a radar would move to track an object but in the case of the new multi-object tracking radar, its 12x6 meter antenna does not move but its electronic beam moves,” he said about the radar.

Multi-Object Tracking Radar (MOTR)​

ISRO’s future missions will need tracking of multiple objects. For this purpose, a Multi-Object Tracking Radar or MOTR is being realized indigenously, which will contribute to Range safety, Impact point monitoring, recovery and re-entry missions. The MOTR will track different stages of launch vehicles simultaneously during nominal and non-nominal missions. The tracking data will be used for computing the Instantaneous Impact Points (IIPs) of the descending/separated objects of the launch vehicle, more accurately.

The configuration of MOTR is derived based on long range tracking requirement of 50 cm x 50 cm object size at a slant range of 1000 km for objects and 30 cm x 30 cm size at a slant range of 800 km in LEO for space-debris. The MOTR operates in L-band frequency (1.3 to 1.4 GHz) with active phased array antenna, capable of tracking ten objects simultaneously. The radar is designed to have a maximum peak power of 830 kW with 4608 radiating antenna elements.

Further, MOTR will also provide the data related to close approach of space debris to the remote sensing satellites in Low Earth Orbit (LEO) and to plan the collision avoidance manoeuvres of these satellites, thus contributing to the safe operation of ISRO’s Space Assets and Space Situational Awareness.

All these radar applications ISRO works with hopefully will have trickle down affect to DRDO labs and some private firms. It worked out that way with rocket tech, etc.

When will the Indian Deep Space Network be completed? Right now it isn't capable enough to tract spacecrafts in the outer space like in the case of Mangalyaan.

IDSN capability is being gradually enhanced . But what is the volume of deep space missions that we will be undertaking in near future ? so obviously ISRO is going slow on that .

India or for that matter any other country will always need to take help of network of antennas across the globe to track the space-crafts traveling in deep space .
this has got nothing to do with capability of IDSN. It is a constrain imposed by geography and physics .

Not much - by the end of this decade we will have three - Chandyaan 2 with a lander (can be handled by IDSN solely) - Mangalyaan 2 with lander and a mission to Venus.

You are comparing Apples and Oranges.

Ok just for Mango man lets see which is better----
---------------------------------------------Tracking Range---------Object size---------Max. number of objects tracked
Upgraded swordfish(DRDO)--------1500 km------------------Cricket ball---------more than 30(un-upgraded version)
MOTR(ISRO)-----------------------------1000/800 Km-------------30X30 cm---------10

Acharya Nagarjuna University will now partner Satish Dhawan Space Centre (SDSC)-SHAR, Indian Space Research Organisation (ISRO) in designing a Multi Object Tracking Radar (MOTR) to be used in defence surveillance.

Vice-Chancellor K. Viyanna Rao said on Friday that ANU has entered into a Memorandum of Understanding with SDSC-SHAR to design the MOTR, becoming the first university in the country to have a tie-up with SDSC-SHAR in designing indigenous radars. India is the fourth nation in the world, after the US, Japan and Germany to design MOTRs, he said.

Because of its enhanced maneuvering capabilities, the GSSAP satellite can get the best possible vantage point for collecting images of other satellites, according to Shelton.

He said the imagery capabilities on the new satellites are “a big leap forward” compared with the ones the U.S. has been using to monitor objects circling the earth.

“Today the way we track threats in geosynchronous orbit is by basically points of light, and as we take a picture of the sky and dwell on that part of the sky, [we know] things that are moving are satellites, things that are stationary are stars … Through our points of light and various other means, we make inferences on what a particular [foreign] satellite can do,” Shelton explained.

But the GSSAP “gives us an ability … to look at literal images of objects in geosynchronous orbit … A picture is worth a thousand inferences because we can see literally what that [foreign] satellite looks like, and you can effectively reverse-engineer and understand what the capabilities are … to a much greater extent than you can today,” Shelton said.

The launch comes at a time when China is rapidly improving its space and anti-satellite capabilities. Pentagon planners worry that in a future conflict, Beijing might shoot down or disable American military satellites that are critical for communications, intelligence-gathering, and targeting.

“There are myriad counter-space threats that we are seeing on the near horizon,” Shelton said. “We’re going to have to adjust our spacecraft constellations to survive in a very different environment from what we’ve had in the past,” and we need “much better situational awareness of what’s going on; hence GSSAP.”

Shelton was asked specifically whether he was worried about space-based weapons or electromagnetic pulse weapons being used against U.S. military satellites.

“All of the above,” he replied.

Shelton declined to go into detail about what capabilities the Pentagon is developing to thwart enemy anti-satellite weapons.

Thanks for Nice Info; But I think any war with two well weaponed nations is the hell; If China can do; Even US can destroy satellites of the China, and that would be create hell for any nation in this edge. No.2 Possibilities are more for Cold War like the US-RUS as US-China, rather of Full Fledge War. China has limited Jurisdiction raise in the Getting Taiwan and All Neighbour's lands where as China is not seems interested to be world power like US to observe and make policy connected to whole world countries. they are only interested in buisness, and their claim lands, and not at all seems interested to be US like world POLICE MAN.

Indeed. Just recently China told the U.S. that there is room for both countries in the Pacific Ocean. China wants the other half.

ISRO Says Multi-Object Tracking Radar Ready for Trials

The indigenously designed Rs. 245-crore multi-object tracking radar (MOTR) is ready to undergo trials, said a senior space scientist at Sriharikota on Saturday.

"The multi-object tracking radar has been installed. It has to undergo trials. Once the trials are satisfactory then it will be ready for use," M.Y.S. Prasad, director, Satish Dhawan Space Centre, told reporters.

According to him, the radar can track around 10 objects simultaneously.

He said the radar can track space debris so that a satellite's direction could be altered to avoid collision.

Prasad said the entire radar is fully developed by the Indian Space Research Organisation (Isro).

He also said the Isro's commercial arm Antrix Corporation has signed an agreement with a US company to launch one of its small satellites.

Great news

So AESA Am i right?
