Bangalore, 16th May 2017: The PES University on Tuesday 16th May 2017 inaugurated a dedicated facility ‘Centre for Research in Space Science and Technology’ for satellite integration and testing. The facility is inaugurated by Dr. BHVS Narayana Murthy, Director, RCI/DRDO.
Dr. M R Doreswamy Chancellor PES University said that, PES University is always keen towards nurturing research and innovation. I am very confident that, this centre will promote creativity, innovation and excellence in space science with special focus on attracting young students to work in the field of space science and nurturing their innate talent.
I am happy to share that THIS CENTRE WITH A STATE-OF-THE ART CLEAN ROOM IS FIRST OF ITS KIND IN PRIVATE UNIVERSITY IN INDIA. We see such specialized centres only at space agencies like ISRO, NASA and abroad universities.
The research centre is established in PES University, Bengaluru to carry out research and provide hands on experience in space technology to the engineering students. The centre consists of Satellite design laboratory equipped with necessary design tools, software and a clean room.
Particulate contamination is extremely important since costly delays and failures in past spacecraft projects have been attributed to the inadequacy or lack of contamination control. In leading space agencies like NASA and ISRO, Spacecraft buildup and some engineering tests were conducted in class 100,000 conventional clean rooms. In line with the established practice for satellite building, PES University established a similar class 100 000 clean room of approximately 35 square meters area to carryout research in space technology leading to the development of small satellites. Temperature, RH and particle counts are maintained as FED STD 209E. The air flow inside Clean room is laminar. The Clean room flooring is of ESD epoxy as per international standard. ESD garments, ESD work tables along with ESD chairs are available inside the clean room for working persons.
RSAT will be the first satellite to be developed in this facility. RSAT is conceived to support the national cause. Major cities along the coastline are highly prone to sea/waterborne terrorist attacks. Supervising the ships, managing the traffic flow into harbors and preventing accidental collisions of ships over high seas is becoming a Herculean task. IMO mandates that Vessels on international voyage must install the Automatic Identification System (AIS) as specified in the SOLAS (Safety Of Life At Sea) Regulation V/19.2.4 implementation schedule. The AIS rule is part of domestic and international effort to increase the security and safety of maritime transportation. AIS provides information automatically and continuously to other ships and even to a competent authority without involvement of ships’ personnel.
AIS network, where several AIS base stations (or shore stations) are connected and controlled by a network technique, was constructed at coastal areas and harbors to improve the ship surveillance and traffic management.
The AIS system coverage range is similar to other VHF applications, essentially depending on the height of the antenna (Line Of Sight system). A typical value to be expected at sea is nominally 20 to 40 nm. The satellite antenna footprint is much larger than the self-organized area of a typical AIS cell and can get the data from a large area of the order of 1000km.
PES has planned to develop a nano satellite – RSAT which picks up AIS signals transmitted by ships over a large area on high seas and transmit them to ground station where the signals are processed and the data of the ships in visible area is extracted.
RSAT is a 3 axis stabilized agile nano satellite weighing 10 Kg and measuring 300mm x 300 mm x 300mm in size with deployable solar panels generating 45 watts solar power. The satellite payload receives AIS signals transmitted by ships in VHF band, stores onboard and transmits to ground station in X-band through a high gain phased array antenna during ground station visibility period. Satellite with S-band omni antenna system supports TTC. Onboard control system with four reaction wheels and three magnetic torquers controls the satellite for sun tracking to generate maximum power and also track ground station for data transfer during ground station visibility period.
RSAT is a satellite being developed as proof of concept which will lead to the development of a constellation of six to eight satellites to have continuous monitoring of ships on high seas.
