PSLV C16 - LAUNCH 20th April, 2011 at 10.12 a.m. - Video

Dear friends here is some of the information we compiled for you. Let us all convey our best wishes to ISRO for success of PSLV C16 Launch.

About PSLV - C16:
PSLV-CI6 is the eighteenth flight of ISRO's Polar Satellite Launch Vehicle, PSLV
In this flight, the standard version of PSLV with six solid strap-on motors is used.
PSLV-CI6 will place three satellites with a total payload mass of 1404 kg –
i. RESOURCESAT-2 weighing 1206 kg,
ii. the Indo-Russian YOUTHSAT weighing 92 kg and
iii.Singapore's X-SAT weighing 106 kg - into an 822 km polar Sun Synchronous Orbit (SSO).

PSLV-CI6 will be launched from the First Launch Pad (FLP) at Satish Dhawan Space Centre SHAR, Sriharikota.

Here is the Video cum powerpoint which can give your overview of PSLV C16 and what going to happen today.

History and Present of PSLV
In 1993 – 900 kg / 900 Km SSO:
PSLV was initially designed for launching 900 kg Indian Remote Sensing Satellites into a 900 km polar SSO. Since the first launch in 1993, PSLV has been successively improved to attain its present capability.

Changes in PSLV over period of time :
The major changes made in PSLV since its first launch include changes in strap-on motors ignition sequence, increase in the propellant loading of
the first stage and strap-on solid propellant motors as well as the second and fourth stage liquid propellant motors, improvement in the performance of the third stage motor by optimising motor case and enhanced propellant loading and employing a carbon composite payload adapter.

PSLV has also become a more versatile vehicle for launching multiple satellites in polar SSOs as well as Low Earth Orbits (LEO) and Geosynchronous Transfer Orbit (GTO). With sixteen successful launches, PSLV has emerged as the workhorse launch vehicle of ISRO and is offered for launching satellites for international customers also.

44 Satellites in last 16 Years :
During 1994-2010 period, PSLV has launched a total of 44 satellites, of which 25 satellites are from abroad and 19 are Indian satellites.

Eighteenth Flight
PSLV C-16 is Eighteenth Flight. So Far there have been two Failures (one in 1993 and 1997 Partial Failure).

RESOURCESAT-2 is the eighteenth Remote Sensing satellite built by ISRO. RESOURCESAT-2 is a follow on mission to RESOURCESAT-I, launched in 2003. RESOURCESAT-2 is intended to continue the remote sensing data services to global users provided by RESOURCESAT-I that has far outlived its designed mission life. Also, it provides data with enhanced multispectral and spatial coverage as well.
RESOURCESAT-2 carries three cameras which are similar to those of RESOURCESAT-I. They are: a high resolution Linear Imaging Self Scanner (LISS-4) operating in three spectral bands in the Visible and Near Infrared Region (VNIR) with 5.8 m spatial resolution and steerable up to ± 26 deg across track to achieve a five day revisit capability; a medium resolution LISS-3 operating in three-spectral bands in VNIR and one in Short Wave Infrared (SWIR) band with 23.5 metre spatial resolution; and a coarse resolution Advanced Wide Field Sensor (AWiFS) operating in three spectral bands in VNIR and one band in SWIR with 56 metre spatial resolution.

Important changes in RESOURCESAT-2 compared to RESOURCESAT-1 are: Enhancement of LISS-4 multispectral swath from 23 km to 70 km and improved Radiometric accuracy from 7 bits to 10 bits for LISS-3 and LISS-4 and 10 bits to 12 bits for AWIFS. Besides, suitable changes, including miniaturisation in payload electronics, have been made in RESOURCESAT-2.

Additional Payload - AIS : RESOURCESAT-2 also carries an additional payload known as AIS (Automatic Identification System) from COMDEV, Canada as an experimental payload for ship surveillance in VHF band to derive position, speed and other information about ships.

200 GB SOLID STATE RECORDERS : RESOURCESAT-2 carries two Solid State Recorders with a capacity of 200 Giga Bytes each to store the images taken by its cameras which can be read out later to ground stations.

The project of the Russian-Indian sceintific-educational satellite YouthSat is developed on the basis of an Agreement between the Federal Space Agency and the Indian Organization of Space Research dated d.d. January 25, 2007.

YouthSat was initially proposed by Dr. ABJ Kalam during his visit to Russia during 2005.

The micro satellite bus is planned and designed to carry different kinds of payloads like earth imaging, atmospheric applications, weather monitoring, stellar observations, scientific experiments etc. It will carry 3 payloads, one designed by Russian students and two by Indian students.

Youthsat 3 Payloads:

1. SolRad
SolRad, Solar Radiation, is the name of equipment being developed by Moscow state university. The experimental equipment SolRad is intended for registration of hard X-ray radiation within the energy ranges of 10-100 keV, measurements of gamma- radiation within the energy ranges 0.02-5.0 MeV and charged particles: electrons with energy of 0.3-3.0 MeV and protons with energy of 3-100 MeV.

2. RaBIT and LVHS
The payloads provided by ISRO are RaBIT (Radio beacon for Ionospheric Tomography) which will be meant for two-dimensional mapping of ionospheric structures- both top and bottom side along the satellite path. And, Limb Viewing Hyper Spectral Imager (Visible) for the altitude profile of neutral and ionized species of the upper atmosphere. Not much information is available on the  Indian institutes workingn on these payloads.

YouthSat is planned to be launched as auxiliary satellite along with ResourceSat-2


This is a developmental project undertaken by CREST (Centre For Research in Satellite Technologies) with partners such as CRISP (Centre for Remote Imaging, Sensing and Processing, NUS), and overseas collaborators (SaTReCi, ISRO, DLR, DTU etc.).

The XSAT project objectives are: (1) To develop a low cost micro-satellite bus capable of performing remote sensing operation in near real-time scenarios (2) To build-up in country capability (resources and facilities) in satellite engineering (3) To promote academic interest for R&D in this area
