Industrial visit at Azista Industries Pvt Ltd

A total of 20 students from the 6th and 8th semesters visited organization. Despite the protocol restrictions and limited access to cleanroom facilities, the visit was well-coordinated, informative, and highly enriching for our students. The detailed explanations about satellite manufacturing processes, cleanroom operations, quality standards, and space technology applications provided valuable practical exposure beyond classroom learning. The interaction with experts significantly enhanced the students’ understanding of real-world industrial practices and advanced technological systems. 1. INTRODUCTION The Department of Electronics and Communication Engineering organized an industrial visit to Azista BST Aerospace located in Sanand, Ahmedabad. The visit aimed to provide practical exposure to satellite system design, assembly, integration, and environmental qualification processes. 2. OBJECTIVES OF THE VISIT • To understand satellite system architecture. • To study Assembly, Integration & Testing (AIT). • To observe environmental testing facilities. • To learn about space-grade electronics and reliability standards. • To understand applications of communication, control, and embedded systems in satellites. 3. COMPANY BRIEFING During the technical briefing session, engineers introduced the company's infrastructure and discussed their first satellite mission, ABA First Runner. The satellite supports remote sensing, maritime monitoring, and surveillance applications. 4. ENVIRONMENTAL TESTING FACILITIES 4.1 Thermal Vacuum (TVAC) Testing The Thermal Vacuum Chamber simulates space conditions including vacuum and extreme temperature cycles to validate satellite performance in orbit. 4.2 Vibration Testing The electrodynamic vibration shaker simulates rocket launch conditions to verify structural integrity and mechanical robustness. 4.3 EMI/EMC Testing The EMI/EMC chamber ensures electromagnetic compatibility between subsystems and validates RF communication stability. 4.4 Magnetic Field & Attitude Control Testing Helmholtz Coil setup is used to simulate Earth's magnetic field. This testing validates the Attitude Determination and Control System (ADCS), reaction wheels, magnetorquers, and magnetometer calibration. 5. CLEAN ROOM EXPERIENCE Before entering the clean room, special clean room coats, hair covers, and shoe covers were provided. The facility maintains Class 100,000 clean room standards to prevent contamination. 6. SATELLITE BUS STRUCTURE The satellite bus structure forms the backbone of the spacecraft. It supports payloads, power systems, onboard computers, and communication modules. 7. SATELLITE SUBSYSTEMS OBSERVED • Battery System – Provides energy during eclipse phase. • Power Control Unit (PCU) – Regulates voltage distribution. • Payload Power & Data Handling (PPDH) – Manages payload communication. • Reaction Wheel Assembly (RWA) – Controls satellite orientation. 8. FIBER TESTING & IMAGE DECODING Engineers demonstrated fiber-based data transmission and conversion of encoded digital signals into reconstructed image output, showing practical applications of digital communication and signal processing. 9. TECHNICAL LEARNING OUTCOMES The visit provided practical understanding of embedded systems, power electronics, RF communication, control systems, magnetic interaction in satellites, and environmental qualification. 10. CONCLUSION The industrial visit to Azista BST Aerospace was technically enriching and provided real-world exposure to satellite manufacturing and testing processes. It strengthened the interest of students in aerospace and satellite communication engineering.
