ISRO’s PSLV-C54/EOS-06 mission with Oceansat-3 and eight nano satellites, including one from Bhutan, lifted off from Sriharikota Space Center at 11.56 am on November 26 marking a major milestone for the Indian space agency Will happen. It will also be very important for NewSpace India Limited (NSIL). The OceanSat series of satellites have enabled the country to develop dedicated applications for oceanographic and atmospheric studies. The launch will include satellites from Dhruva’s Thibolt and Pixels Anand as well as Bhutan’s BhutanSat.

The OceanSat series satellites carry an array of sensors that help study chlorophyll concentration, phytoplankton blooms and atmospheric aerosols. These studies help in special predictive modeling like cyclone predictions. The first Oceansat carried an Ocean Color Monitor (OCM) and a Multi-frequency Scanning Microwave Radiometer (MSMR) for oceanographic studies. Followed with further enhancements. After the scatterometer on Oceansat 2 reached its end of life, Scatsat 1 was launched with another scatterometer at the same Ku-band as Oceansat 2. The latest satellite, Oceansat 3, is the main This will naturally be for continuity, but also increase sea surface temperature measurements,” explained Girish Linganna, space and aerospace expert and director at ADD Engineering Components India Limited.

BhutanSat is part of Prime Minister Narendra Modi’s space diplomacy initiative, and India is assisting Bhutan in building and launching its latest satellite, BhutanSat. ISRO provided assistance to Bhutan in more ways than one. Bhutanese engineers worked with ISRO to build the nanosatellite. “ISRO is working on the primary payload, which is an optical camera for remote sensing. The country can use the satellite for agriculture, forestry or land mapping. Prime Minister Modi had promised a satellite for the Himalayan nation in 2020 as part of his government’s Act East policy.

Bengaluru-based spacetech startup company Pixel’s third hyperspectral satellite ‘Anand’ will also be part of the launch. Pixel had earlier become the first Indian company to launch a commercial satellite into space by launching ‘Shakuntala’ in April through SpaceX. Anand is a hyperspectral microsatellite that weighs less than 15 kg and has a total coverage of over 150 wavelengths which enables it to observe the Earth in much greater detail than today’s non-hyperspectral satellites which cover more than 10 wavelengths. will enable Satellite images can be used to track pest outbreaks, map wildfires, identify soil erosion and oil spills.

Pixxel’s hyperspectral satellites have the ability to provide hundreds of bands of information with global coverage at very high frequencies, making them ideal for disaster relief, agricultural monitoring, energy monitoring and urban planning applications. They are equipped to beam down 50 times more information with unprecedented detail than other conventional satellites in orbit.

The company has already partnered with Rio Tinto and Data Farming, who will use hyperspectral datasets to identify mineral resources and monitor for active and prescribed cropping issues, respectively. The imagery captured from this satellite will provide the team targeted inputs for improving the form factor and imaging capabilities of the next batch of commercial-class satellites.

Dhruv Space, another space company, will launch its Thybolt 1 and Thybolt 2 satellites into low Earth orbit as part of this launch. “Dhruv Space, in fact, was the first to sign an MoU with IN-SPACe for space activities like testing and launch of satellites and satellite components. The current Dhruv payloads are CubeSats that the company will employ to support international CubeSat deployers. Their team in Austria is working on bringing in international clients,” said Linganna.

Space experts like Smt Kesson, Founder and CEO of Space Kidz India, pointed out that OceanSat will play a major role in studying surface winds, sea level and monitoring phytoplankton blooms, which are basically algae that play an important role. plays. Oxygen is produced in oceans and fresh water ecosystems. It’s also going to study sediments and aerosols suspended in water, and observe chlorophyll because we need to protect our ecosystems. “The study of tectonic plate movements in the ocean floor can be of great help to the general public and more so to fishermen who do not have proper warning systems to alert them when they are in the deep sea. As India is surrounded by three I think upgrading the system and launching the Oceansat 3 series will be extremely beneficial to the country,” Kesson told The Week.

He said all eyes will also be on Dhruva Space’s Thibault and Pixel Anand as they claim their satellites will be used to detect pest infestations, map wildfires and identify soil stress and oil slicks. Apart from this, identification and active monitoring of mineral resources will be done. Finding Crop Problems

“I think this launch is going to be very important for the country as one satellite will focus on the oceans and the other will reveal the secrets hidden under the earth. India has strong mineral reserves but, unfortunately, scientists are still Haven’t been able to find any equipment or tools that can go and identify the deep places of mineral deposits.
