Rakesh Sasibhushan, CMD Antrix said: “Antrix is looking at 50/60 launches SSLVs a year and in the next 10 years, we see a business potential of ₹1500-2000 crore annually.”


ISRO is developing SSLV with the intention of 50-60 launches per year by late 2020s. If it happens it would mean a SSLV launch every week!

ISRO is looking to outsource manufacturing of PSLV & SSLV in order to focus on the human spaceflight program:

The Indian Space Research Organisation (ISRO) and its commercial wing Antrix on Wednesday said they are willing to outsource manufacturing of Polar Satellite Launch Vehicle (PSLV) and the Small Satellite Launch Vehicle (SSLV) so that the space agency could focus on the proposed human space programme. ISRO held discussions a week ago with a consortium of industries regarding PSLV industrialisation with the objective of easing ISRO to focus on human space programme and research and development activities.

"Definitely, in my opinion, in the ISRO activity, industry is going to play a major role. If only the industry is taking the load, ISRO can work out on human space programme and research and development activities," ISRO chairman K Sivan said.

He said the industry should help in manufacturing PSLV as well as SSLV, adding ISRO had already worked out a model. With this model in a year, the PSLV was supposed to be produced by the industry. "That is our ambition and target," Sivan said.

He was addressing a press conference here to announce the Bengaluru Space Expo (BSX), a three-day event starting from September 6 at the Bengaluru International Exhibition Centre(BIEC).

BSX-2018 will have 100 exhibitors, 56 speakers, and 600 official delegates participating. There will be a separate pavilion for human space programme or Gaganyaan, which was announced by Prime Minister Narendra Modi in his Independence Day address this year.

PM Modi had said an Indian astronaut would be sent to space by 2022. India will be the fourth country after the USA, Russia, and China to send humans to space. Sivan said informal discussions had been initiated with the Indian Air Force on selection of the crew. Once selected, it would take two-three years to train them.

He also said ISRO would need to take the help of a foreign country for advanced training of the crew. "We have not decided which country we will choose for training. Russia, Germany, and USA have the facilities," Sivan added.

On the PSLV outsourcing, the ISRO chief said industry partners Hindustan Aeronautics Limited (HAL), Larsen and Tubro, Godrej were among those who took part in the discussions. "It is possible to produce PSLV from this consortium. Already we have started working on that," Sivan said.

Sivan said the industry would have a huge role to play in Gaganyaan and in building facilities for mission control centre and launch pad. Antrix Managing Director Rakesh Sasibhushan said the small satellite service was an $18 billion market (roughly Rs. 1.27 lakh crores) and they were looking at 50-60 launch vehicles per year.

"We are looking for a 50-60 vehicles per year, which is definitely going to make it commercially viable to produce...So the general capacity we are building, we are looking at a revenue of around Rs. 1,500 crores to Rs. 2,000 crores per year," he said. Atrix was discussing with various industry players in this connection, he added.

An interview of ISRO head stated that 85% of the cost is other cost and only 15% is for parts and fuel. So, 85% will go for labour and quality inspection. The reduction in labout to 10% of normal will reduce overall 75% of the cost directly. The reduction in weight and number of parts and fuel will reduce 10% of cost. So, I would not be surprised if the launch cost actually is 15% of normal launch cost


The cost of PSLV C28 rented to UK cost 28 million Euros. This would have been lower if it was for Indian launch. ISRO charges higher for foreign launches. So, even going by the figure of PSLV C28 for UK, the launch cost should come to 15% of 28 million Euros which is roughly equal to $4million USD. The Indian cost for launch is likely to be $3million whereas foreign launch is likely to be $5million. There may be premium added to get more profits. But the cut throat pricing will only come to this.

The labour cost will also involve cost to fund the development programmes, salary etc and hence it is unlikely to be reduced to 10% unless the scale goes up drastically. Even then, the cost is likely to be in $7-8 million. The cost of electron rocket launch is $5million for 150 kg and will still be 3 times less competitive than SSLV

Why does SSLV weigh 120tons? When other countries like USA has ICBM minuteman which can reach 1200km at 50 ton, why India can't make a similar ICBM type missile which can launch satellite to 500-600km orbit for 50-60tons?

One reason is the big dog-leg SSLV performs to avoid overflying Sri Lanka.

ISRO scouting for new location on Gujarat coast for SSLV
Quote
In addition, ISRO is scouting for a location on the western sea coast near Gujarat to set up another launch pad for Small Satellite Launch Vehicles (SSLV).
Quote
“We have evaluated several locations. The first two SSLV launches will take place from Sriharikota. After that they will move to the new location,” the official said.

This should avoid the payload loss due to dog-leg for SSLV.

But I hope the choice of Gujarat on the west coast wasn't a political move as it happens to be the home state of the Prime Minister. A launch base on the east coast would have been more safer for strategic reasons. Unless they plan to do launches to retrograde orbit as well that is, in which case a launch location on the west coast would have made better sense.

Why can't the launch be made from West bengal or odisha or even Lakshadweep?

As of equatorial launches,Shriharikota is an optimal location as earth additional 0.4 km/s advantage and Shriharikota is a very unique place that meets the requirement of ISRO.SHAR is both accessible as well as relatively less uninhabited.SHAR is on an island touching pulicat lake which has advantages for polar as well as equatorial launches.

How is it an advantage for polar when you have to do a huge dog-leg maneuver during flight to avoid overflying Sri Lanka?

The ideal location for polar launches is on the Tamil Nadu coast between Rameswaram and Kanyakumari. 

1. No dog leg maneuvers around Sri Lanka.  In fact, there is no land mass between this coast and Antarctica

2. This part of the coast sees fewer cyclones

3. Easy transportation from ISRO's development, testing and production centres at Thiruvananthapuram, Valiamala, Mahendragiri, Sriharikota and Bangalore. 

4. Safe from a strategic point of view

Gujarat coast does not make that much sense to me.

In fact, ISRO had considered a launch site at Kulasekarapatnam in Tuticorin district for these very reasons.

I would say the best location for polar launches would be from west bengal

- No overflying sri-lanka
- Able to stay in sight of indian ground stations the entire mission duration thereby simplifying mission planning
- No longer having all launch infrastructure in one part of country (Not a good idea from a strategic perspective)

I was wondering why we didn't choose to make LV manufacturing & launch facilities at Lakshdweep or A&N Islands.

Design for Small Satellite Launch Vehicle ready
https://www.thehindu.com/news/national/kerala/design-for-small-satellite-launchvehicle-ready/article25792402.ece
From article:
Quote
On the launchpad, the SSLV will stand 34 metres tall, 10 metres shorter than the Polar Satellite Launch Vehicle (PSLV) and around 15 metres shorter than the Mk-II version of the Geosynchronous Satellite Launch vehicle (GSLV). It is also a ‘thinner’ launch vehicle, possessing a diameter of just two metres.
Quote
With a lift-off mass of 120 tonnes, the SSLV can place a 500 kg payload at a height of 500 km in the Low Earth Orbit (LEO). The SSLV has three solid motor stages, and like the PSLV and GSLV, can accommodate multiple satellites, albeit smaller ones. Unlike the PSLV and GSLV, the SSLV can be assembled both vertically and horizontally.

SSLV:- This mini-PSLV can be assembled in 3-4 days as compared to 40 days for a normal-size rocket. The first test of SSLV, which will be used to launch small satellites weighing less than 500 kg, is due in June-July.

Source: NDTV <https://idrw.org/isros-new-rocket-likely-to-carry-2-defence-satellites/>

1. ISRO will fly two small defence satellites in July or August this year on its new rocket SSLV. ”We are planning to fly two defence satellites, each weighing about 120 kg in our new rocket SSLV this July or August. The rocket design recently underwent a detailed integrated technical review,” K Sivan, ISRO Chairman, told news agency IANS on Wednesday.
2. He said the total weight of the payload that will be carried by the SSLV on its first flight will be about 500 kg. While the two satellites would weight about 120 kg each, there will be adaptors and others that would weigh about 300 kg. The total weight of the rocket will be 110 tonne.

So the SSLV to carry DRDO sats in its maiden test launch?
