Satellite launch: ISRO to earn half the cost from foreign parties

Of the 104 satellites to be launched on February 15, only three are Indian.

ISRO will recover half of the total cost incurred for next week's launch of 104 satellites from the foreign capsules mounted on its workhorse rocket PSLV-C37.
ISRO will recover half of the total cost incurred for next week's launch of 104 satellites from the foreign capsules mounted on its workhorse rocket PSLV-C37. Of the 104 satellites to be launched on February 15, only three are Indian.

"We want to make optimum use of our capacity. We are launching our three satellites. One is of 730 kgs while other two are 19 kgs each. We had additional space of 600 kgs. So we decided to accommodate 101 satellites," ISRO chairman A S Kiran Kumar said.

"Roughly half of our cost will be covered by the foreign satellites we are launching," he said, without revealing the exact amount ISRO will earn from foreign customers.

The space agency has earned more than USD 100 millions by launching foreign satellites. It also has achieved mastery on launching smaller satellites.

ISRO will launch a record 104 satellites through its workhorse rocket PSLV-C37 on February 15 from the Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh.

These 101 satellites are nano-satellites and belong to foreign nations, including the US and Germany.

The Indian satellites are from the Castrosat series.

Last year, ISRO launched record 20 satellites at one go. The highest number of satellites launched in a single mission is 37, a record that Russia set in 2014. The US space agency NASA launched 29.

Kumar said ISRO is at present doing tests on its lander for Chandrayaan 2 at its facility in Mahendragiri in Tamil Nadu and Challakere in Karnataka.

"It is an indigenous development and tests are on. It's a control descend. So it has engines that allow a control descend," Kumar said.

Chandryaan 2 mission seeks to make a landing on the moon.

The ISRO said that all SAARC countries, except Pakistan, have given their consent for the South Asian satellites project envisioned by Prime Minister Narendra Modi as "India's gift to its neighbours".

Kumar said that the manned mission project is "not a top priority" for the ISRO, as he emphasised on enhancing space infrastructure.

Story of the Week - Indian Space Research Organization
Indigenous development of Telemetry & Telecommand Processor (TTCP)

ISRO Satellite Centre (ISAC), Bengaluru, is the lead centre for conceptualisation, design, development, fabrication, integration and testing of complex satellite technology. Spacecraft Checkout Group of ISAC is responsible for integrated spacecraft testing to ensure the flight worthiness of the spacecraft built at ISAC. During the testing, ground systems will communicate to spacecraft via the same uplink and downlink signals, as in space. The spacecraft typically use ISRO formats for telemetry and telecommand (downlink and uplink), for which indigenous equipment are being used. However, the interplanetary spacecraft use an international standard known as CCSDS - Consultative Committee for Space Data Systems. Presently equipment are being imported for telemetry reception and telecommand transmission requirements.

As part of ‘Make in India’ campaign, indigenous development of Telemetry & Telecommand Processor (TTCP) was taken up by ISRO and successfully realised. This processor replaces the expensive imported equipment. This will be used in Integrated Spacecraft Testing of Low Earth Orbit, Geostationary Orbit and Interplanetary Spacecraft. This system is configurable to meet uplink and downlink requirements of both CCSDS and ISRO standards. Multiple Clients can remotely access this system for data and monitoring. Productionisation of this system will be initiated with the help of Indian industry.

The system was developed on an FPGA (Field Programmable Gate Array) platform taking advantage of System On Chip (SOC) features. Telemetry & Telecommand sections were realised as separate hardware. Telemetry input can be received at 70 MHz Intermediate Frequency (IF) and Pulse Code Modulation (PCM) level. Telecommand outputs are available at PCM, Frequency Shift Keying (PSK) / Phase Shift Keying (FSK) and 70 MHz IF. All the features of TTCP are programmable remotely, using the soft-core processor onboard FPGA. A computer with server software is used for configuration management, remote monitoring, Telemetry data streaming, Telecommand echo and secured access for Telecommand & Control from multiple remote clients. This system is an amalgamation of diverse software, hardware devices and digital signal processing techniques which work in tandem to provide the required functionalities.

This indigenously developed Processor was successfully deployed for the first time in checkout of GSAT-19, which is scheduled to be launched shortly.

I am posting regarding the ISRO's Second Vehicle Assembly Building (SVAB) which will be completed this year in June.

Here are some highlights from tender issued in 2013-14, I have this 117 page document in PDF format, so I can't upload all of it's pages but I have lost the link too.
My purpose is to indicate about Indian HLV program!

[Indx TechStyle]

The new VAB that would be ready for operations before the end of this year is designed to accomodate larger rockets that are under study by ISRO in addition to LVM3. Especially the 10T to GTO class HLV. There are a few associated design changes like provision to support an auxiliary umbilical tower, cranes that handle larger solid boosters etc..
Third Launch Pad will have lot more.

Anyway, Height of building is 96 metres! Capable of storing even super heavy rockets if estimates are true!:biggrin2:

India is going to make much bigger rockets than it currently operates.

PSLV-C37 / Cartosat -2 Series Satellite

India's Polar Satellite Launch Vehicle, in its thirty ninth flight (PSLV-C37), will launch the 714 kg Cartosat-2 series satellite for earth observation and 103 co-passenger satellites together weighing about 664 kg at lift-off into a 505 km polar Sun Synchronous Orbit (SSO). PSLV-C37 will be launched from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. It will be the sixteenth flight of PSLV in 'XL' configuration (with the use of solid strap-on motors).

The co-passenger satellites comprise 101 nano satellites, one each from Israel, Kazakhstan, The Netherlands, Switzerland, United Arab Emirates (UAE) and 96 from United States of America (USA), as well as two Nano satellites from India. The total weight of all the satellites carried onboard PSLV-C37 is about 1378 kg.

PSLV-C37 also carries two ISRO Nano satellites (INS-1A and INS-1B), as co-passenger satellites. These two satellites carry a total of four different payloads from Space Applications Centre (SAC) and Laboratory for Electro Optics Systems (LEOS) of ISRO for conducting various experiments.

The 101 International customer Nano satellites are being launched as part of the commercial arrangements between Antrix Corporation Limited (Antrix), a Government of India company under Department of Space (DOS), the commercial arm of ISRO and the International customers.

PSLV-C37 is scheduled to be launched on Wednesday, February 15, 2017 at 9.28 Hrs IST from Sriharikota

Regarding timeline, India had first launched 10 satellites in single launch but was beaten up by US, Russia & China later.
India again caught up with 20 in a launch last year (as that of China's).
Currently, Russia has record of 37 satellites in a single launch, which is to be cracked on Feb 15th.

@Indx TechStyle
Good news brother, thanks for all the heavy lifting.
A ironical question-- Even though the last post was very satisfying,there is a lot of technical data in this post, is it safe?

[Indx TechStyle]

there is a lot of technical data in this post, is it safe?

This isn't even a fraction of data what I daily collect.
BTW, it's very safe.
I just posted about few drawings for assembly facility for HLV. Not blueprints of HLV.
Hope you understand.

And trust me, I'm a responsible person regarding any such issue.

I do brother and I know about you being a responsible person, I have been reading your posts for last one year, still had to ask, for what its worth this thread is really great and your content is really great.
BTW, I wanted to ask about one of your posts In India's Defense Proc. thread about Pinaka 2 having an accuracy of 60 m accuracy, is that true ?
Post#484, India's Defence Proc. thread, Ma. Parrikar's report to parliament.

Pinaka 2 having an accuracy of 60 m accuracy, is that true ?
Post#484, India's Defence Proc. thread, Ma. Parrikar's report to parliament.

There are two versions of Pinaka.
(Please note between Pinaka 2 & Pinaka Mk2).
Guided version has high accuracy.
