LACHIT-1

LACHIT-1 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand LACHIT-1 rather than just read about it. In short: Live Amateur Communication Hub for Innovative Technologies – One or LACHIT-1 was a student-developed experimental satellite built by Assam Don Bosco University (ADBU) in Assam, India. It is widely regarded as the first satellite developed from the Northeastern region of India.

Key takeaways

LACHIT-1 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect LACHIT-1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of LACHIT-1 from memory before moving on to harder problems.

Reference excerpt

Live Amateur Communication Hub for Innovative Technologies – One or LACHIT-1 was a student-developed experimental satellite built by Assam Don Bosco University (ADBU) in Assam, India. It is widely regarded as the first satellite developed from the Northeastern region of India. The satellite was launched on 12 January 2026 aboard the PSLV-C62 mission from the Satish Dhawan Space Centre in Sriharikota. However, the mission was lost following an anomaly in the rocket's third stage shortly after launch, preventing the payloads from reaching orbit. The project involved more than 50 students and faculty members from across the northeastern states and was developed with technical support from the private space company Dhruva Space.

Background Assam Don Bosco University initiated its institutional space programme in 2022 with the aim of developing regional capacity in satellite technology, mission operations, and space engineering. The LACHIT-1 satellite emerged from this programme as a student-led mission designed to provide hands-on experience in spacecraft design, integration, and operations. The satellite was named after Lachit Borphukan, the 17th-century Ahom military commander remembered for his leadership during the Battle of Saraighat.

Development The spacecraft was developed under Dhruva Space’s ASTRA (Accelerated Space Technology Readiness & Access) for Academia programme. The satellite was built using Dhruva Space's P-DoT nanosatellite platform and integrated using a collaborative workflow between university students and professional engineers. Subsystem testing, launch integration, and mission readiness reviews were conducted in coordination with Dhruva Space engineers.

Mission profile LACHIT-1 was intended to operate in a Sun-synchronous orbit as a technology demonstration satellite for communications and environmental monitoring. The mission objectives included:

Demonstrating store-and-forward satellite communication using amateur radio frequencies. Testing Internet-of-Things (IoT) sensors in space. Providing training in spacecraft operations for students. Supporting emergency communication systems in disaster-prone regions. The planned operational lifetime of the satellite was approximately one year.

Payload The satellite carried:

Store-and-forward communication system — enabling short messages sent from ground stations to be stored onboard and retransmitted during later satellite passes. IoT environmental sensors — designed to measure atmospheric temperature, humidity, and pollution levels. The communication payload was intended to support amateur radio operators and emergency communication scenarios where terrestrial networks may fail.

Ground segment Mission control and satellite communication were planned to be managed from a dedicated ground station established at Assam Don Bosco University's Tapesia campus near Guwahati. The ground station included VHF/UHF communication systems and Dhruva Space's Integrated Space Operations Command Suite for satellite monitoring and telemetry reception.

Launch LACHIT-1 was launched on 12 January 2026 aboard the PSLV-C62 mission from the First Launch Pad at the Satish Dhawan Space Centre in Sriharikota. The launch was part of India's first space mission of 2026 and carried multiple payloads, including the hyperspectral Earth-observation satellite EOS-N1 as the primary payload.

Launch failure Shortly after liftoff, the PSLV-C62 launch vehicle experienced an anomaly in its third stage, resulting in loss of thrust and preventing the rocket from placing its payloads into orbit. The failure caused the loss of the primary payload EOS-N1 as well as all co-passenger satellites, including LACHIT-1. The incident marked the second consecutive failure of a PSLV mission within a year and prompted investigations by the Indian Space Research Organisation into the launch anomaly.

Timeline

Legacy Despite the mission failure, LACHIT-1 represented a milestone for Northeast India's participation in space technology and student-driven aerospace research. The project demonstrated the growing role of academic institutions and regional innovation ecosystems in India's expanding space sector.

Worked examples

Example 1 — a first encounter with LACHIT-1

Start with the simplest possible case. Write down what LACHIT-1 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to LACHIT-1 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about LACHIT-1 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of LACHIT-1

In research: LACHIT-1 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses LACHIT-1 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: LACHIT-1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2026 in spaceflight, Satellites of India, Spacecraft launched in 2026, so understanding it makes those chapters shorter.
In everyday life: Look for LACHIT-1 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
