On 11 December, the Indian Area Analysis Organisation will launch India’s latest protection satellite tv for pc RISAT-2BR1, together with a string of economic small satellites for ISRO’s worldwide purchasers, by way of a industrial association with NewSpace India Restricted (NSIL). The launch is deliberate for 3.25 pm on 11 December, when ISRO will launch the ten satellites on a Polar Satellite tv for pc Launch Car (particularly, the PSLV-C48).
This would be the 50th launch of the PSLV, and will happen from the First Launch Pad on the Satish Dhawan Area Centre in Sriharikota, Andhra Pradesh. It should even be the second time that the PSLV is flown within the ‘QL’ configuration (with 4 strap-on motors).
Here is all the things we all know up to now concerning the varied payloads (satellites) that can be launched on this mission.
The RISAT-2BR1 satellite tv for pc is India’s radar imaging and earth commentary satellite tv for pc. Weighing about 628 kg, the satellite tv for pc can be positioned in a low-earth orbit of 576 km, at an inclination of 37 diploma.
RISAT-2BR1 comes with Artificial Aperture Radar (SAR) capabilities, which can give it superior, all-weather capabilities the place radar surveillance is anxious.
“The RISAT-2BR1 uses SAR that can penetrate clouds and observe images on the ground with a ground sampling distance of barely 35 cms,” mentioned Rajendra Prasad, chief enterprise officer, Satellize (previously Exseed Area).
Israel’s Duchifat 3
Three kids from an Israeli faculty have travelled to India to see a satellite tv for pc designed and constructed by them — the ‘Duchifat 3’ — being launched on the PSLV-C48 mission by ISRO. Duchifat Three is the third within the collection of Israeli student-made satellites, inbuilt a joint effort by college students of Herzliya Science Middle and Sha’ar HaNegev Excessive Faculty college students, the satellite tv for pc is designed to serve kids from throughout the nation to “observe the Earth”.
“It is a photo satellite used for ecological research of Earth from space. The size of the satellite is 10x10x30 cm (3U) and it weighs 2.3 kg. The students worked for almost two and a half years to build it. The satellite will be of good help to agriculturists,” one of many donors for the venture and head of ICA Basis Zeev Miller advised PTI.

The PSLV-C48 mission will function a revolutionary satellite tv for pc check expertise by Japan, within the QPS-SAR microsatellite. The 100-kg artificial aperture radar (SAR) microsatellite is wanting to supply all-weather, 24/7 earth commentary companies for rent. These satellites provide distant surveillance and “near real-time” views of Earth from house.
The satellite tv for pc, designed and constructed by the QPS Institute (iQPS) — precursors for a deliberate constellation of 36 satellites. In line with Gunter’s Area Web page, the satellite tv for pc can distinguish objects which can be a metre-long, and can be able to figuring out vehicles on the highway.
The 2 demonstration QPS-SAR satellites designed by iQPS can be launched by ISRO in PSLV missions in 2019 and 2020.
Italy’s Tyvak 0092/COMMTRAIL
The COMMTRAIL satellite tv for pc, which additionally goes by the manufacturer-provided designation ‘Tyvak 0092’, is a cubesat designed by Tyvak – an end-to-end satellite tv for pc manufacturing service based mostly in California. The COMMTRAIL cubesat will show Search & Rescue capabilities for Italy.
COMMTRAIL is a satellite tv for pc that may function an indication and validation for a machine-to-machine communication expertise that may purchase indicators from floor terminals and downlink to floor stations, dedicated to search-and-rescue missions. The payload is a Extremely-Excessive-Frequency (UHF) software-defined radio (SDR) outfitted with a custom-made deployable helix antenna.
USA’s Tyvak 012/Pathfinder Tech Demo
The Pathfinder Expertise Demonstrator, which additionally goes by the manufacturer-provided designation ‘Tyvak 0129’, is a cubesat tech demonstration designed by Tyvak – an end-to-end satellite tv for pc manufacturing service based mostly in California. It should put to check quite a lot of enhancements to the efficiency and effectivity of Tyvak’s cubesat techniques.
The principle objective of the mission is to check a brand new micro-electrospray thruster constructed by Busek Area Propulsion Programs.
The satellite tv for pc is the primary in a collection of pathfinding missions by Tyvak Nano-Satellite tv for pc Programs, which is operated by the NASA Ames Analysis Centre in California’s Silicon Valley.
A gaggle of 4 ‘LEMUR’ minisatellites will even be launched on the PSLV-C48 mission, constructed and designed by Spire International, a US-based satellite tv for pc producer. The LEMURs are a part of a community of satellites which have computerized identification techniques (AIS) that turn out to be useful for quite a lot of civil and navy functions.
The 4 satellites being launched on the PSLV-C48 mission will be a part of an present constellation of minisatellites (different LEMURs) already in orbit. The LEMURs will add to Spire’s capabilities in meteorology in addition to ship-traffic monitoring.
1HOPSAT (or, the 1st-generation Excessive Optical Efficiency Satellite tv for pc, expanded) is a satellite tv for pc a part of an earth commentary constellation designed by Hera Programs, a California-based satellite tv for pc startup. The HOPSATs are constructed based mostly on a previously-tested prototype (1HOPSat TD). Every of those HOPSATs will home an imaging telescope to document photos and video of customer-specified areas of the Earth at sub-meter floor decision. The visuals, as soon as recorded, can be relayed to Earth by way of floor stations.
A time frame after the satellite tv for pc is deployed by PSLV-C48, photo voltaic panels and antennas will deploy, and the primary imaging and communications will start. The satellites can be powered by electrical propulsion.
1HOPSAT is the primary in a collection of eight preliminary satellite tv for pc launches, the place it is going to be the secondary payload, in launch missions in 2020-2021, and can be positioned in a 600-km-orbit.
