SSLV-D1
The SSLV-D1 was the first mission of the Small Satellite Launch Vehicle (SSLV). Due to a sensor fault during separation of second stage and subsequent initiation of Open Loop Guidance by onboard computer to salvage the mission, the upper stage did not fire for planned duration and payloads were ultimately injected into a decaying orbit not achieving the objectives of mission. Details ISRO developed a small satellite launch vehicle (SSLV) to cater the launch of up to 500 kg satellites to Low Earth Orbits on ‘launch-on-demand’ basis. SSLV-D1 mission launched EOS 02, a 135 kg satellite, with a planned Low Earth orbit of about 350 km altitude, at an inclination of about 37 degrees. EOS-02 was an Earth observation satellite designed and realised by ISRO. This microsat-type satellite offered advanced optical remote sensing operating in infrared band with high spatial resolution. The bus configuration was derived from IMS-1 bus. The mission also carried the AzaadiSAT satellite. Azaa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small Satellite Launch Vehicle
The Small Satellite Launch Vehicle (SSLV) is a small-lift launch vehicle developed by ISRO with payload capacity to deliver to low Earth orbit () or to Sun-synchronous orbit () for launching small satellites, with the capability to support multiple orbital drop-offs. SSLV is made keeping low cost, low turnaround time in mind with launch-on-demand flexibility under minimal infrastructure requirements. The maiden flight SSLV-D1 was conducted on 7 August 2022, from the First Launch Pad, but failed to reach a stable orbit. In the future, a dedicated launch site called SSLV Launch Complex (SLC) near Kulasekharapatnam in Tamil Nadu will handle SSLV launches to Sun-synchronous orbit. After entering the operational phase, the vehicle's production and launch operations will be done by a consortium of Indian firms along with NewSpace India Limited (NSIL). Vehicle description The SSLV was developed with the aim of launching small satellites commercially at drastically reduced p ...

EOS 02
EOS-02 (formerly known as Microsat-2A) was an Indian Earth observation microsatellite developed by the Indian Space Research Organisation as a test payload on the maiden launch of the Small Satellite Launch Vehicle (SSLV). EOS-02 was based on Microsat-TD. The objective behind EOS-02 was to realize and fly an experimental imaging satellite with short turnaround time to showcase launch on demand capability. It was intended to be used for cartographic applications at a cadastral level, urban and rural management, coastal land use and regulation, utilities mapping, development and various other GIS applications. The satellite carried two payloads: a mid-wavelength and a long-wavelength infared camera with a 6m resolution. Launch EOS-02 was launched on Small Satellite Launch Vehicle's maiden flight SSLV-D1 at 03:48 UTC / 09:18 IST on 7 August 2022, but due to the final VTM stage failure, the rocket entered a transatmospheric orbit of 356 km x 76 km (221 mi x 47 mi) instead ...

AzaadiSAT
AzaadiSAT was an Indian Earth observation 8U Cubesat weighing around 8 kg developed by the Space Kidz India as a test payload on the maiden launch of the Small Satellite Launch Vehicle (SSLV). It was hitching a ride with EOS-02, the primary satellite of the mission. The launch on 7 August 2022 was a failure in the rocket leading to imminent return to atmosphere for the rocket and the satellites (AzaadiSAT and EOS-02) it carried, destroying them all. Its successor AzaadiSAT-2 was launched onboard SSLV-D2. Development It was created to mark India’s 75th year of independence. This anniversary was being marked in 2022 by the Azadi Ka Amrit Mahotsav celebrations throughout the country, and the CubeSat was part of this campaign. AzaadiSAT was built by schoolgirls from 75 schools across India. 10 girls from each school were involved, for a total of 750 students involved. The mission was created to give girls from lower-income backgrounds the opportunity to learn the fundamentals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Satish Dhawan Space Centre
Satish Dhawan Space Centre - SDSC (formerly Sriharikota Range - SHAR) is a rocket launch centre (spaceport) operated by Indian Space Research Organisation (ISRO). It is located in Sriharikota, Tirupati district of Andhra Pradesh. Sriharikota Range was renamed in 2002 after ISRO's former chairman Satish Dhawan. History Sriharikota island was chosen in 1969 for a satellite launching station. The centre became operational in 1971 when an RH-125 sounding rocket was launched. The first attempted launch of an orbital satellite, Rohini 1A aboard a Satellite Launch Vehicle, took place on 10 August 1979, but due to a failure in thrust vectoring of the rocket's second stage, the satellite's orbit decayed on 19 August 1979. SHAR was named as 'Satish Dhawan Space Centre SHAR' (SDSC), on 5 September 2002, in memory of Satish Dhawan, former chairman of the ISRO. The SHAR facility now consists of two launch pads, with the second built in 2005. The second launch pad was used for launches ...

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Sensing
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Earth and other planets. Remote sensing is used in numerous fields, including geography, land surveying and most Earth science disciplines (e.g. hydrology, ecology, meteorology, oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others. In current usage, the term ''remote sensing'' generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation). It may be split into "active" remote sensing (when a signal is emitted by a satellite or aircraft to the object and its reflection detected by ...

Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Standard Time
Indian Standard Time (IST), sometimes also called India Standard Time, is the time zone observed throughout India, with a time offset of UTC+05:30. India does not observe daylight saving time or other seasonal adjustments. In military and aviation time, IST is designated E* ("Echo-Star"). It is indicated as Asia/Kolkata in the IANA time zone database. History After Independence in 1947, the Union government established IST as the official time for the whole country, although Kolkata and Mumbai retained their own local time (known as Calcutta Time and Bombay Time) until 1948 and 1955, respectively. The Central observatory was moved from Chennai to a location at Shankargarh Fort in Allahabad district, so that it would be as close to UTC+05:30 as possible. Daylight Saving Time (DST) was used briefly during the China–India War of 1962 and the Indo-Pakistani Wars of 1965 and 1971.
