- Uttarakhand to get 179 weather stations in next 4 months
- For accurate weather predictions, the Himalayan state would get 179 weather stations in the next four months.
Besides, three locations – Mussoorie, Mukteshwar and Pithorgarh – have been finalized for the installation ion of Doppler radar.
- The Met authorities told the chief secretary that after the start of automated weather stations, making real time weather predictions would be possible. It will help provide updates on floods, rains, landslides, cloudburst and hailstorm. The timely information would provide major help in farming, disaster management and tourism.
- For the technical support in operation of the stations, an MoU has been signed with the Indian Met Department (IMD). The data provided by the weather stations would be linked with the IMD network and weather predictions would be available after every 15 minutes.
- The weather stations would have 28 auto rain gauge, 25 advance surface observation and 16 auto snow gauge.

· ISRO’s PSLV-C40 lifts off from Sriharikota
- ISRO’s PSLV-C40 carrying Cartosat-2series satellite and 30 other spacecraft lifts off from Sriharikota.
- The “Cartosat-2 Series” and 29 other satellites inserted into a 505-kilometer sun-synchronous orbit.
- Later, the payload Microsat developed by the ISRO will be taken down to a lower orbit at 359-kilometer height and launched using the ‘multiple engine switch-on’
- This is the fourth time the novel method has been used by the ISRO for placing satellites in multiple orbits in a single flight.
Gk bit – Space Satellites
- A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word “satellite” refers to a machine that is launched into space and moves around Earth or another body in space.
- Earth and the moon are examples of natural satellites. Thousands of artificial, or man-made, satellites orbit Earth. Some take pictures of the planet that help meteorologists predict weather and track hurricanes.
- There are different types of Satellites launched by ISRO as follows:
- The Indian National Satellite (INSAT) system is one of the largest domestic communication satellite systems in Asia-Pacific region with nine operational communication satellites placed in Geo-stationary orbit. Established in 1983 with commissioning of INSAT-1B, it initiated a major revolution in India’s communications sector and sustained the same later. GSAT-17 joins the constellation of INSAT System consisting 15 operational satellites, namely – INSAT-3A, 3C, 4A, 4B, 4CR and GSAT-6, 7, 8, 9, 10, 12, 14, 15, 16 and 18.
Earth Observation Satellites
ð Starting with IRS-1A in 1988, ISRO has launched many operational remote sensing satellites. Today, India has one of the largest constellations of remote sensing satellites in operation. Currently, *thirteen* operational satellites are in Sun-synchronous orbit – RESOURCESAT-1, 2, 2A CARTOSAT-1, 2, 2A, 2B, RISAT-1 and 2, OCEANSAT-2, Megha-Tropiques, SARAL and SCATSAT-1, and *four* in Geostationary orbit- INSAT-3D, Kalpana & INSAT 3A, INSAT -3DR.
ð Varieties of instruments have been flown onboard these satellites to provide necessary data in a diversified spatial, spectral and temporal resolutions to cater to different user requirements in the country and for global usage. The data from these satellites are used for several applications covering agriculture, water resources, urban planning, rural development, mineral prospecting, environment, forestry, ocean resources and disaster management.
ð Satellite Navigation service is an emerging satellite based system with commercial and strategic applications. ISRO is committed to provide the satellite based Navigation services to meet the emerging demands of the Civil Aviation requirements and to meet the user requirements of the positioning, navigation and timing based on the independent satellite navigation system. To meet the Civil Aviation requirements, ISRO is working jointly with Airport Authority of India (AAI) in establishing the GPS Aided Geo Augmented Navigation (GAGAN) system. To meet the user requirements of the positioning, navigation and timing services based on the indigenous system, ISRO is establishing a regional satellite navigation system called Indian Regional Navigation Satellite System (IRNSS)
(a) GPS Aided GEO Augmented Navigation (GAGAN):
ð This is a Satellite Based Augmentation System (SBAS) implemented jointly with Airport Authority of India (AAI). The main objectives of GAGAN are to provide Satellite-based Navigation services with accuracy and integrity required for civil aviation applications and to provide better Air Traffic Management over Indian Airspace. The system will be interoperable with other international SBAS systems and provide seamless navigation across regional boundaries. The GAGAN Signal-In-Space (SIS) is available through GSAT-8 and GSAT-10.
(b) Indian Regional Navigation Satellite System (IRNSS) : NavIC
This is an independent Indian Satellite based positioning system for critical National applications. The main objective is to provide Reliable Position, Navigation and Timing services over India and its neighbourhood, to provide fairly good accuracy to the user. The IRNSS will provide basically two types of services
Standard Positioning Service (SPS)
Restricted Service (RS)
Wherever, Standard Positioning Service (SPS) for civilian users and
Restricted Service (RS) for strategic users.
ð AstroSat is the first dedicated Indian astronomy mission aimed at studying celestial sources in X-ray, optical and UV spectral bands simultaneously. The payloads cover the energy bands of Ultraviolet (Near and For), limited optical and X-ray regime (0.3 keV to 100keV). One of the unique features of AstroSat mission is that it enables the simultaneous multi-wavelength observations of various astronomical objects with a single satellite.
ð AstroSat with a lift-off mass of 1515 kg was launched on September 28, 2015 into a 650 km orbit inclined at an angle of 6 deg to the equator by PSLV-C30 from Satish Dhawan Space Centre, Sriharikota. The minimum useful life of the AstroSat mission is expected to be 5 years.
Mars Orbiter Mission
ð Mars Orbiter Mission is ISRO’s first interplanetary mission to planet Mars with an orbiter craft designed to orbit Mars in an elliptical orbit of 372 km by 80,000 km. Mars Orbiter mission can be termed as a challenging technological mission and a science mission considering the critical mission operations and stringent requirements on propulsion, communications and other bus systems of the spacecraft.
ð Chandrayaan-1, India’s first mission to Moon, was launched successfully on October 22, 2008 from SDSC SHAR, Sriharikota. The spacecraft was orbiting around the Moon at a height of 100 km from the lunar surface for chemical, mineralogical and photo-geologic mapping of the Moon. The spacecraft carried 11 scientific instruments built in India, USA, UK, Germany, Sweden and Bulgaria.
- Chandrayaan-2 will be an advanced version of the previous Chandrayaan-1 mission to Moon.Chandrayaan-2 is configured as a two module system comprising of an Orbiter Craft module (OC) and a Lander Craft module (LC) carrying the Rover developed by ISRO.
