This is the 11th mission using PSLV-XL confi guration Vehicle. PSLV-C31 launch is from Second Launch Pad (SLP), SDSC, SHAR. The previous mission of PSLV from SLP was PSLV-C27/IRNSS-1D. In SLP, the Vehicle stacking and Satellite assembly are carried out at Vehicle Assembly Building (VAB). Subsequent to closure of Payload Fairing and integrated checks, the Launch Vehicle is moved to launch pad for fi nal countdown and launch.

IRNSS-1E is I-1K Bus based satellite which has a lift off mass of 1425 kg. This satellite is similar to that of the previously launched satellites viz. IRNSS-1A, 1B, 1C and 1D. This is a navigation satellite realized to provide navigation solution in a constellation with land coverage over India and spreading around 1500 km around Indian main land. IRNSS-1E structure uses standard I-1K CFRP sandwich central internal structure with all exposed aluminium sandwich panels. This type of structure has good launch heritage in PSLV meeting the launch vehicle stiffness and strength requirement. The satellite is powered by two solar arrays, which generate power up to 1,660 W and has a life-time of more than ten years. PAYLOADS • Navigation payloads The navigation payloads work in L5 and S bands, employ dual helix antenna and transponders working in both bands. It employs Rubidium Atomic Frequency standard as the atomic clock which is the heart of the Satellite. • Ranging payload This is working in C band and used for meeting the ranging requirement of the Satellite.

  • Orbital Lifetime Predictions
    Orbital LIFETIME PREDICTIONS An ASSESSMENT OF model-based BALLISTIC COEFfiCIENT ESTIMATIONS AND ADJUSTMENT FOR TEMPORAL DRAG co- EFfiCIENT VARIATIONS M.R. HaneVEER MSc Thesis Aerospace Engineering Orbital lifetime predictions An assessment of model-based ballistic coecient estimations and adjustment for temporal drag coecient variations by M.R. Haneveer to obtain the degree of Master of Science at the Delft University of Technology, to be defended publicly on Thursday June 1, 2017 at 14:00 PM. Student number: 4077334 Project duration: September 1, 2016 – June 1, 2017 Thesis committee: Dr. ir. E. N. Doornbos, TU Delft, supervisor Dr. ir. E. J. O. Schrama, TU Delft ir. K. J. Cowan MBA TU Delft An electronic version of this thesis is available at http://repository.tudelft.nl/. Summary Objects in Low Earth Orbit (LEO) experience low levels of drag due to the interaction with the outer layers of Earth’s atmosphere. The atmospheric drag reduces the velocity of the object, resulting in a gradual decrease in altitude. With each decayed kilometer the object enters denser portions of the atmosphere accelerating the orbit decay until eventually the object cannot sustain a stable orbit anymore and either crashes onto Earth’s surface or burns up in its atmosphere. The capability of predicting the time an object stays in orbit, whether that object is space junk or a satellite, allows for an estimate of its orbital lifetime - an estimate satellite op- erators work with to schedule science missions and commercial services, as well as use to prove compliance with international agreements stating no passively controlled object is to orbit in LEO longer than 25 years.

  • Remote Sensing in India
    Remote Sensing in India India’s Remote Sensing starts following the successful demonstration flights of Bhaskara-1 and Bhaskara-2 satellites launched in 1979 and 1981, respectively, with the development of indigenous Indian Remote Sensing (IRS) satellite program. Indian Remote Sensing (IRS) satellite system was commissioned with the launch of IRS-1A, in 1988. With many satellites in operation, IRS is the largest civilian remote sensing satellite constellation in the world providing imageries in a variety of spatial resolutions, spectral bands and swaths. Data from Indian Remote Sensing satellites are used for various applications of resources survey and management under the National Natural Resources Management System (NNRMS in following: Pre harvest crop area and production estimation of major crops. Drought/irrigation monitoring and assessment based on vegetation condition. Flood risk zone mapping and flood damage assessment. Hydro-geomorphologic maps for locating underground water resources for drilling well. Snow-melt run-off estimates for planning water use in downstream projects. Land use and land cover mapping. Urban planning. Forest survey. Wetland mapping. Environmental impact analysis. Mineral Prospecting. Coastal studies. India’s Recent IRS satellites 2012: Radar Imaging Satellite-1 (RISAT-1) imaging of the surface features during both day and night under all weather conditions. 2011: Megha-Tropiques, for studying the water cycle and energy exchanges in the tropics. 2011: RESOURCESAT-2 to continue the remote sensing data services to global users provided by RESOURCESAT-1, and to provide data with enhanced multispectral and spatial coverage as well. 2010: Cartosat-2B to provide multiple spot scene imageries. It is capable of imaging a swath (geographical strip) of 9.6 km with a resolution of better than 1 metre.

  • Sapphire-Like Payload for Space Situational Awareness Final
    Sapphire-like Payload for Space Situational Awareness John Hackett, Lisa Li COM DEV Ltd., Cambridge, Ontario, Canada ([email protected]) ABSTRACT The Sapphire satellite payload has been developed by COM DEV for a Surveillance of Space mission of the Canadian Department of National Defence, which is scheduled to be launched later in 2012. This paper presents a brief overview of the payload, along with the potential for using this optical instrument as a low cost, proven Space Situational Awareness hosted payload on geostationary satellites. The Sapphire payload orbits on a dedicated satellite and hence the payload was not required to actively point. The proposed hosted payload version of Sapphire would be enhanced by incorporating a two dimensional scan capability to increase the spatial coverage. Simulations of the hosted payload version of Sapphire performance are presented, including spatial coverage, approximate sensitivity and positional accuracy for detected resident space objects. The moderate size, power and cost of the Sapphire payload make it an excellent candidate for a hosted payload space situational awareness application. 1. INTRODUCTION The Sapphire payload is described elsewhere [1] and was developed by COM DEV on a moderate budget for MDA Systems Ltd. and the Canadian Department of National Defence and is scheduled to fly in 2012. The Sapphire payload combines the SBV heritage [2] through the telescope design/contractor, with high quantum efficiency CCDs and advanced high reliability electronics. The Sapphire mission [3] was developed by the Canadian Department of National Defence (DND) as part of its Surveillance of Space project. MDA Systems Ltd. was the mission prime contractor, and COM DEV was the payload prime contractor.

Angelo, I-80126 Napoli, Italy * Correspondence: [email protected] Abstract: The Virgo detector, based at the EGO (European Gravitational Observatory) and located in Cascina (Pisa), played a significant role in the development of the gravitational-wave astronomy. From its first scientific run in 2007, the Virgo detector has constantly been upgraded over the years; since 2017, with the Advanced Virgo project, the detector reached a high sensitivity that allowed the detection of several classes of sources and to investigate new physics. This work reports the Citation: Bersanetti, D.; Patricelli, B.; main hardware upgrades of the detector and the main astrophysical results from the latest five years; Piccinni, O.J.; Piergiovanni, F.; future prospects for the Virgo detector are also presented.
