TSAT-1A: INDIA'S FIRST PRIVATE MILITARY SPY SATELLITE

Tata Advanced Systems Ltd on April 7 announced the "successful deployment" of the country's first military-grade geospatial satellite, the Sub-metre Optical Satellite, which was assembled and tested in India. SpaceX's Falcon 9 rocket on Sunday (April 7) launched the TSAT-1A satellite from the Kennedy Space Center in Florida, US.

1. This achievement follows the collaboration agreement signed between TASL and Satellogic in November.

India’s current inventory of military spy satellites, primarily developed by ISRO, is limited. TASL, however, aims to address this gap by envisioning a constellation of similar satellites in the future. Reports suggest that the company’s manufacturing facility is equipped to produce up to 25 low earth orbit (LEO) satellites annually, in collaboration with Satellogic Inc., a key player in sub-metre resolution earth observation satellites.

What is TSAT-1A?

1. TSAT-1A is India's first privately built sub-meter resolution earth observation satellite.
2. TSAT-1A is an optical sub-meter-resolution Earth observation satellite that was built by Tata Advanced Systems Limited (TASL) in collaboration with Latin American company Satellogic Inc.
3. It was assembled in TASL's Assembly, Integration, and Testing (AIT) plant in Karnataka and was launched by SpaceX's Falcon 9 rocket from the Kennedy Space Center, Florida.

Strategic advantages of TSAT-1A’s inclined orbit, which enables it to frequently revisit certain areas of interest more, as compared to traditional satellites in Sun Synchronous Polar Orbits (SSPO).

Key Features of TSAT-1A

1. Key strengths in capturing military-grade imagery of Earth's surface with sub-meter resolution.
2. Equipped with both multispectral and hyperspectral imaging capabilities, allowing data collection across a wide range of wavelengths
3. Greater collection capacity, wider dynamic range, and low-latency delivery of data.
4. The satellite is equipped to deliver high-resolution optical satellite images and is expected to achieve full functionality in a few months.

Benefits for Indian Defense Forces

1. The TSAT-1A satellite will be used by the Indian Defense Forces to gather strategic information. It has the potential to enhance preparedness, response capabilities and strategic decision making.
2. The satellite is a major step forward for India's space program and will help the country to better monitor its borders and respond to natural disasters.
3. It is also a significant achievement for the private sector, which is playing an increasingly important role in India's space industry.

Despite ISRO’s satellite capabilities, which include imagery sharing, their application is constrained by coverage limitations. Consequently, India has often relied on US companies to meet its imaging needs, a dependency accentuated by recent tensions with China along the Line of Actual Control (LAC).

FAQs:

Q1: What is hyperspectral imaging?

Hyperspectral imaging (HSI) is a non-invasive technique that uses light to analyze the structure of objects and surfaces by breaking the light into spectral bands. HSI provides spectral information for each pixel, in addition to 2D spatial images.

HSI has many applications, including:

• Agriculture, Waste sorting and recycling, Eye care, Food processing, Mineralogy, Surveillance, Astronomy, Chemical imaging, Environment, and Civil engineering
