India’s Earth imaging satellite, in the Cartosat-2 series satellite, is the primary satellite carried by PSLV-C37. The CartoSat-2D is the fifth earth observation satellite in the CartoSat series, and is the heaviest satellite on board.This satellite is similar to the earlier four satellites of the Cartosat-2 series. After its injection into a 505 km polar Sun Synchronous Orbit by PSLV-C37, the satellite will be brought to operational configuration following which it will begin providing regular remote sensing services using its Panchromatic and Multi-spectral cameras. It is powered by solar arrays which generate 986 watt and two Li- ion batteries and has its own fuel. The satellite can be controlled through reaction wheels, magnetic torquers and hydrazine thrusters. Various aspects of the satellite has been thoroughly tested on the ground, including a dynamic balancing test, a solar panel illumination test and a solar panel deployment test. The planned operational period of the satellite is 5 years.
The imageries from Cartosat-2 series satellite will be useful for:
1)cartographic
applications
2)urban
and rural applications
3)coastal
land use and regulation
4)utility
management like road network monitoring
5)water
distribution, creation of land use maps
6)change
detection to bring out geographical and manmade features
7)various
other Land Information System (LIS) and Geographical Information
System (GIS) applications.
The
two Inertial Navigational System (INS-IA & INS-1B) use a
computer, motion sensors and rotation sensors (gyroscopes) to
calculate the position, orientation and velocity (direction and
speed) of a moving object without external references. It is
a versatile and modular Nano satellite bus system envisioned for
future science and experimental payloads. INS-1A
and INS-1B will 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 INS-1A
and INS-1B satellites
are expected to be operational for 6 months.
-
Design and develop a low cost modular Nano satellite in the weight range of 10 kg capable of carrying payloads up to a weight of 5 kg.
-
Provide an opportunity for ISRO technology demonstration payloads.
-
Provide a standard bus for launch on demand services.
-
Provide an opportunity to carry innovative payloads for Universities / R&D laboratories.
Out
of 96 satellites from USA, 88 satellites are from Planet
Labs, a company that sells Earth imaging service. Yes, the
company which purchased Terra Bella, Google’s
satellite imaging business. These satellites are
small CubeSats known
as Dove satellites, Dove(
flock-3p) nano
satellites are
a group of remote sensing satellites which will image the earth every
day for its commercial, environmental,
humanitarian purposes. Flock
2p, which is a constellation of 12 Dove satellites, was also launched
by Isro in the PSLV-C34
mission in
last June, that had 20 satellites on board. Flock 3p will form
a constellation with an ideal mid morning pass timing, that
allows for clear images with minimum shadows.
Next
8 satellites are called LEMUR nano
satellites meant for providing vessel tracking using automated
identification system, besides carrying out weather measurement using
GPS Radio Occulatation. The
Lemur satellites are owned and managed by Spire
Global. These are
a part of a constellation of satellites that track ships in open
waters which is useful for real-time monitoring of large ships.
The data is used by insurance companies, for the safety of the
ships, to monitor illegal fishing and to take measures against
piracy.the Lemur satellites are also equipped with instruments for
monitoring the weather, which improves the accuracy of weather
forecasts.
The
PiezoElectric Assisted Smart Satellite Structure PEASS from
The Netherlands is a
nanosatellite meant
to test and qualify cutting edge “smart structures”, which
combine composite panels, piezoelectric materials and next generation
sensors.Smart
structures will enable fine angle control, thermal and vibration
compensation, improving all types of future Earth observations, such
as environmental and planetary mapping, border and regional imaging.
This new technology will help keep Europe on the cutting edge of
space research, potentially improving the cost and development time
for more accurate future sensor platforms including synthetic
aperture optics, moving target detection and identification, and
compact radars.The
results of the technology demonstration will be disseminated to the
industry through web sites, papers, presentations and courses. The
PEASSS is built by a European consortium of Partners, lead by Dutch
research institute TNO and owned by Innovative Solutions in Space.
The
Overall Project Goal is To develop and test the following smart
structures:
-
piezo actuated “smart panels” for pointing of optical instruments/sensors
-
piezo actuated “smart panels” for power harvesting
-
fiber bragg gratings for composite structure strain and temperature measurement
-
next generation of power conditioners for future applications in space missions.
The DIDO-2 is
a microgravity research nanosatellite built by SpacePharma
from Switzerland. a
platform for conducting biochemical and physical experiments in
microgravity, allowing scientists to investigate phenomena that are
normally obscured by gravity on Earth. Currently, access to
microgravity research is restricted to the International Space
Station, which is prohibitively expensive. SpacePharma
allows customers, mainly pharmaceutical companies, to design
experiments meant for space. The customers can monitor and control
the experiments from their own location. The DIDO-2 is the first
satellite to be launched by SpacePharma.
BGUSat is a technology demonstration nanosatellite from Israel based on the CubeSat architecture. The payloads on board are a camera, a space GPS, and an optical communication system. There is an automatic housekeeping program on board to monitor the communications and power functions. Israeli Aerospace Industries has built the satellite in cooperation with students from the Ben Gurion University. The main objective of the mission is so that students can learn the planning and development of satellites. The students will learn about telemetry systems, attitude control, power, sensors and integration. There are deployable solar panels for power.
The Nayif-1 is
a nanosatellite from the United Arab Emirates (UAE) is the
smallest and lightest passenger on board. The Nayif-1 is the first
nanosatellite by UAE, and has been built by engineering students. The
Nayif-1 was initially slotted to fly on board a Spacex Falcon 9. The
Nayif-1 will pass over the UAE twice a day. The morning pass will be
used by students, whereas the evening pass is for amateur radio
communications. The students have created a special ground station
for receiving telemetry data and have created a dashboard to display
greeting messages in Arabic. The satellite will also collect a large
amount of environmental space data.
The
Al-Farabi-1 is a nano-satellite from Kazakhstan. The Al-Farabi-1
is the first student nano-satellite from Kazakhstan, and is
built by the Al-Farabi
Kazakh National University. The
main payload is a 3MP sensor. There are solar panels on all the sides
of the satellite. There are 4 sun sensors on board, a 3 axis
magnetic sensor, a 3 axis gyro sensor, 3 reaction wheels and a 3 axis
magnetorquer, which will all be used to control the satellite. A
ground station has been built for downlink and uplink operations. The
satellite will orbit around the earth fourteen times every day, with
each orbit lasting 97 minutes
The
flight of the rocket is expected to last sixteen minutes. The
satellites will start separating after that, over a period of roughly
ten minutes. The CartoSat-2D will be deployed first, followed by
pairs of the nanosatellites. The nanosatellites are packed into
quadpack dispensers for being released into orbit. The entire
operation is expected to last about 28 minutes.
Isro will also be streaming the launch live on its site. Finally, a live web stream of the launch will also be available on the DoordarshanYouTube channel.
Wishing
team ISRO all the best....
WOW... ISRO go onn....
