RISAT-2 was launched before RISAT-1 with a mission life of 10 years. So I thought this would be its replacement. Wiki says RISAT-1 has been declared non-operational. So we just have the RISAT-2BR1 operational now ? Or does the RISAT-2 still have some life left ?Replacement for RISAT 1??? (C band vs X band)
We should be having RISAT 2B(PSLV C46 / 22 MAY 19), 2BR1(PSLV C48 / 11 DEC 19) now operational. Risat 2, i couldn't find much about it. But given 10 year declared lifetime, and given the history of past satellites overshooting the expected lifetime, it may still be active.RISAT-2 was launched before RISAT-1 with a mission life of 10 years.

Does SSAB have space to integrate full vehicle? IIRC wasn't SSAB for gs1 and boosters ? And vehicle had to be shifted to vab for further process. If so isn't gslv f10 already in vab?GSLV F10/GISAT-1 : Spacecraft GISAT-1 has arrived at SDSC SHAR on 23 December, launch aiming for late January 2020.

According to regional media report GISAT-1 has been delivered to SDSC SHAR Sriharikota from URSC, Bangalore on 23 December 2019. GSLV F10 is being integrated in SSAB (Solid Stage Assembly Building) and launch is targeting late January 2020 from Second Launch Pad.

The launch of GISAT-1 is expected to happen in late January. We still should have about a full month left to launch, so why was the satellite sent to SDSC this early ? Usually satellites arrive a week or so ahead of the launch, this is too early.Does SSAB have space to integrate full vehicle? IIRC wasn't SSAB for gs1 and boosters ? And vehicle had to be shifted to vab for further process. If so isn't gslv f10 already in vab?
Read with this the cartosat launch was held recently from SLP, so VAB was occupied till then. Any chance we could see the utilisation of SVAB? (I know it's remote, as it isn't inaugrated yet)
This is entirely new information for me. Kudos to you sir for digging this up.Bit old news. We are investing in Galileo ? Since when ? @BMD @vingensys you guys have anything more on this ?
EU SNUB: India to join European satellite project Galileo which Britain is LOCKED OUT OF
INDIA is ready to pump more than £170 million (€200million) into the EU’s Galileo satellite system, which Britain is likely to locked out of despite having invested more than £1 billion, as well as developing much of its technology.

However, no decision has been taken about whether India will have access to the Public Resource Signal (PRS), an encrypted service for public authorities for “security sensitive use”. A report on the Indian news website the Business Standard suggested the country’s Government was ready to invest €200million. It quoted a “European Commission official” as saying: “The Indian government is expected to take a final decision on its equity contribution for the project by June.”
The official said it was not yet clear whether India would be able to access the PRS.
Officials said it was not clear if India would have access to the Public Resource Signal (PRS), which was vital for certain commercial applications.
The official added: "Once, it is sorted out, a decision will be conveyed at the earliest.”
A European Commission spokeswoman did not dispute the accuracy of the report, but told Express.co.uk it was important to distinguish between two things.

She said: “First, it is possible for third countries to access the Public Regulated Service signal ('user segment'), subject to certain preconditions.
“It is for the Council to decide whether the conditions to do so are met at the end of the negotiating process. The Council adopted negotiating mandates with US and Norway in July 2016.
She added: “Second, there are security-related restrictions for third countries when it comes to accessing information related to the evolution of Galileo, and in particular, procurement.
“Third countries (and their companies) cannot participate in the development of security sensitive matters, such as the manufacturing of PRS-security modules.

“Those rules do not prevent a third country from using the encrypted signal of Galileo, provided that the relevant agreements between the EU and the third country are in place as stated above.”
Dr Stuart Eves, an independent consultant who was previously Lead Mission Concepts Engineer for Surrey Satellite Technology Limited, told Express.co.uk he would "not be greatly surprised" if India had decided to invest in Galileo.
He added: "The UK's departure from the Galileo programme creates a hole that this engagement with India may be designed to fill.
"The Indians have a regional navigation system based on GEO satellites called IRNSS.
"Historically there was proposed Chinese involvement in Galileo, but they were subsequently excluded."
The bitter row over Britain’s contribution to Galileo has been raging for more than a year.
In March 2018, the Commission confirmed the UK was likely to excluded from some aspects of the project, especially relating to PRS.
In August, UK Prime Minister Theresa May announced the Government was to spend £92 million on a feasibility study to consider the development of a British rival system.

Speaking to the BBC, UK Space Agency boss Graham Turnock said: “If we want to build our own system now we’d benefit from a lot of learning and we have a simpler project to deliver because it would not be a project that is being managed by 28 separate member states.
“There’s no reason why we shouldn’t do.
“It’s perfectly within our capability on the basis of the initial analysis we have made.”
Andrew Stroomer, business development director with Airbus Defence and Space, told Express.co.uk in October: “We would like Galileo to continue with the participation of the UK.
“But if you look at Galileo, the UK has contributed some of the most complicated parts of that.
“We don’t do everything – but we do enough to show we are capable of building such a system for the UK. From an industry point of view, we have the capability."
Just before the end of the year, Mrs May said the UK would no longer be seeking to reclaim the €1.4billion (£1.2billion) spent so far on the project, prompting the resignation of Science Minister Sam Gyimah.
Meanwhile India signalled its interest in the space sector in November by launching a rocket carrying 31 hi-tech satellites, prompted UK critics to ask why Britain STILL pays the country almost £100million a year in emergency foreign aid.
EU SNUB: India to join European satellite project Galileo which Britain is LOCKED OUT OF
Well this is just speculation on my part. The Americans, I believe, are developing a global GNSS system by linking together a lot of Geo-positioning systems together. The US' GPS, Japan's QZSS, India's IRNSS et al. A civillian variant already exists but the Americans want to make it for military use. That way one user can use signals from another's satellites for military positioning and targeting. That also makes it very difficult any type of ASAT weapon against military satellites. I don't know if Galileo is a part of the system, it probably is.This is entirely new information for me. Kudos to you sir for digging this up.
But I'm baffled with this. I can't figure out the imp question WHY? & WHY GALILEO?
Yes, i had read those report of clubbing various sat-nav systems with gps. Good idea and should considerably reduce the probability of jamming the signals.Well this is just speculation on my part.

The EU, on the other hand wants to make sure the US doesn't have a monopoly in GPS systems. Thus are developing the Galileo and positioning it as a competitor to the US GPS in the civilian market. Of course any such venture is expensive, thus the EU wanted China to be a part of it initially. But that isn't possible anymore given the recent history with China. So who is left ? India.
Of course the article in the media says UK is being kept out, don't know much about it but I reckon the Brexit has something to do with it. If UK is really out as the article suggests, then the funding needs would be greater allowing India to increase equities in the venture.
