I told you. SSLV is Indian equivalent of Chinese Kuaizhou.
Air launched orbital too has been envisaged and in study by a private company called Agnikul. A submarine launched version too might be there.

Low cost, mass produced & quickly assembled rockets to launch any satellite immediately during trouble. I hope we see at least submarine launched variant in next decade.

May be orbital launch not detected by any country. So, can be kept secret.

Launch will be detected when the object starts flying. The rocket is generally very big to be able to hide its launch

FRANCE-INDIA SPACE COOPERATION, FIRST ARGOS4 INSTRUMENT TO FLY ON OCEANSAT3 SATELLITE SET FOR LAUNCH IN JANUARY 2020

Argos is the only global satellite-based data collection and location system of its kind dedicated to studying and preserving the environment. Created in 1978 on the initiative of CNES and the U.S. National Oceanic and Atmospheric Administration (NOAA), it is today operated by CLS (Collecte Localisation Satellite), a subsidiary of CNES. Since Argos entered service, three generations of instruments have succeeded one another. Eumetsat and the Indian Space Research Organization (ISRO) joined the programme in 1997 and 2007 respectively.

Measuring variations in ocean temperature, currents and salinity, monitoring volcanic activity, tracking ice cover and wildlife migration, and supporting maritime transport management are some of the many applications that Argos serves. The Argos system is built around radiotransmitters whose signals are received by dedicated instruments flying on Earth-orbiting satellites. These signals are recorded and then downlinked to receiving stations and data centres for processing.

The first fourth-generation Argos4 instrument is set to fly in January 2020 on India’s Oceansat3 satellite, which will serve marine biology and ocean-observing and monitoring applications. Delivery of the payload module is scheduled this June. CNES is system architect and overseeing development of the ground and space components, in partnership with a consortium of Toulouse-based SMEs—Mecano ID, Soterem, Alten SO, Nexio Steel, Scalian and NEXEYA—federated under the NewSpace Factory banner. In its role nurturing the space SME industrial base, CNES is giving close support to these firms to help them hone their skills. The instruments are being supplied by Thales Airborne Systems. Argos4’s objective is to assure continuity of the Argos2 and Argos3 missions while offering better performance and capacity, thanks chiefly to a wider range of frequencies.

Alongside this fourth generation of instruments, CNES is investing in the future to develop the Argos-Neo demonstrator, a miniaturized Argos4 instrument built with commercial-off-the-shelf telecommunications macrocomponents. Argos-Neo will fly on the ANGELS nanosatellite scheduled to launch at the end of this year.

France and India have established a longstanding partnership like no other in space. This cooperation has left an indelible mark on their relations, encompassing many areas of science, technology and applications, notably to develop sounding rockets and liquid-propulsion engines, to fly payloads, build joint satellites, devise training programmes, conduct satellite communications experiments and launch satellites.

PSLV-C45/EMISAT MISSION

India’s Polar Satellite Launch Vehicle (PSLV), in its 47th mission (PSLV-C45), will launch EMISAT, the primary satellite and 28 international customer satellites from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch is tentatively scheduled at 0930 Hrs on April 01, 2019, subject to weather conditions.

Weighing about 436 kg, EMISAT based on ISRO’s Indian Mini Satellite -2 (IMS-2) bus platform. The satellite is intended for electromagnetic spectrum measurement.

The PS4 orbital platform is envisaged to provide a microgravity environment for research organisations and academic institutes to perform experiments. In this mission, the PS4 hosts three payloads, namely, Automatic Identification System (AIS) from ISRO, Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India and Advanced Retarding Potential Analyzer for Ionospheric Studies (ARIS) from Indian Institute of Space Science and technology (IIST).

The 28 international customer satellitesare from four countries, viz. Lithuania, Spain, Switzerland and USA. All these satellites are being launched under commercial arrangements.

Chandrayaan 2 scheduled to launch in April will carry NASA's laser instruments to Moon

India's lunar mission Chandrayaan 2, scheduled to launch next month, will carry NASA's laser instruments that allow scientists to make precise measurements of the distance to the Moon, according to the US space agency officials.

During the Lunar and Planetary Science Conference held at Texas, US last week, NASA confirmed that Chandrayaan 2 and Israeli lander Beresheet, due to touch down April 11, will each carry NASA-owned laser retroreflector arrays.

"We're trying to populate the entire surface with as many laser reflector arrays as we can possibly get there," Lori Glaze, acting director of the Planetary Science Division of NASA's Science Mission Directorate, was reported as saying by Space.com.

Retroreflectors are sophisticated mirrors, that reflect laser light signals sent from the Earth. The signals can help pinpoint precisely where the lander is, which scientists can use to precisely calculate the Moon's distance from Earth.

While five such instruments already exist on the lunar surface, they have some flaws, according to Simone Dell'Agnello, a physicist at the National Institute for Nuclear Physics National Laboratory at Italy.

"The existing reflectors are big ones," said Dell'Agnello adding that individual reflectors instead of arrays, would waste fewer laser pulses and allow more-precise measurements of the moon's surface.

Those analyses could become so detailed that scientists could see the daily rise and fall of any lander surface the device is resting on as that surface expands and contracts with the Moon's dramatic temperature changes.

Operational not commercial. They have yet to find commercial user for Mk2 let alone Mk.3

Not intended rather than found. India's launch frequency isn't enough to fulfill what India wants at first place.

Isro finally opens door for people to watch rocket launches

HIGHLIGHTS

• Isro has built a viewing gallery in the form of a stadium which can presently accommodate around 5,000 people
• The gallery facing the two launchpads will give a clear line of sight of the rocket and its launch

NEW DELHI:

Indian Space Research Organisation
(Isro) has finally opened its door to people who wish to catch a glimpse of spectacular launches of its multi-storeyed tall and tonnes-heavy rockets from the

Satish Dhawan Space Centre
in Sriharikota, an island in Andhra Pradesh.


Monday's liftoff of PSLV-C45 carrying a DRDO payload Emisat and 28 foreign satellites will be the first such launch which spectators can witness at the space agency's island, which is over 100km north of Chennai. The agency's move to open its high-security launch facility for people for free is on the lines of National Aeronautics and Space Administration (Nasa), which too allows people in the US to watch its space activities, including rocket launches.


The viewing gallery, built like a stadium, can accommodate around 5,000 people. The gallery faces the two launchpads and will give a clear line of sight of the rocket and its launch.

Talking to TOI, Isro chairman K Sivan said: "The new stadium set up on the island can accommodate 5,000 spectators. But as a precautionary measure, we will allow only 1,000 people for Monday's launch. As the launch is at 9.30am, the entry at the stadium will only be till 8am to avoid last-minute hassles. The gallery is located 2-3km from the launchpad and will give a clear and better view of PSLV and GSLV launches. If all goes smoothly, we will allow 5,000 people for the next launch. We will later make some changes at the stadium to accommodate 10,000."



The Isro chief, who will inaugurate the viewing gallery on Sunday, said the opening of the launch centre for the public has been part of his vision to "take Isro to people" to increase public awareness about space activities.


On the eligibility criteria, Sivan said, "Only Indian citizens and children above 10 years will be allowed entry. People have to first register themselves online at the Isro website. They also have to sign an agreement online that will make it clear that Isro won't be liable for any untoward incident at the stadium or Sriharikota launch centre. On filling up all required documents online, people will get an entry pass which they have to download, take a print and show it to security while entering the island."

On safety measures and other arrangements for visitors, Sivan told TOI, "Adequate safety systems have been placed at the stadium for the public. We have also chosen food vendors who will provide snacks to people for money. Toilet and washroom facilities have also been built. There are big screens installed at the stadium that will provide information about the launch, inside view of the space control room and post-launch space activities and the press conference."


The Isro chief said the "stadium is a part of the theme park, which will also have a museum and life-size rocket models to help visitors get a better understanding and feel of rockets".


He said Isro is taking these efforts with an objective to encourage youngsters to join the space sector and increase people's knowledge about India's advancement in space activities.
