Write a short note on: (i) Mobile Satellite Services (MSS) (ii) Environmental monitoring

In short

Mobile Satellite Services (MSS) give voice and data links by satellite to users on the move, such as ships, aircraft and handheld terminals, while environmental monitoring uses satellites to track weather, land, water, forests and oceans. Assets like CMS-03 and INSAT-3D aid cyclone warnings and drought monitoring in Andhra Pradesh.

Model answer

Ghissu Editorial · Verified 4 Oct 2026

Introduction
Mobile Satellite Services (MSS) and environmental monitoring underpin India’s technological progress and climate adaptation, with ISRO’s CMS-031 satellite launched in 2025 marking a significant advance. These technologies are crucial for enhancing connectivity, disaster management, and sustainable resource use, aligning with national development goals.
Institutional Framework
•

ISRO’s Satellite Leadership

CMS-03 supports strategic communication in the Indian Ocean; the INSAT-3D series aids weather monitoring, reflecting strong space tech capacity.

•

State-Level Integration

Andhra Pradesh uses satellite data in MGNREGA and PMFBY, integrating satellite data into rural development3 and agriculture. The National Remote Sensing Centre (NRSC) also regulates data distribution, ensuring secure and efficient use of satellite imagery.

Implementation Challenges and Outcomes
•

Connectivity Gaps

Rural internet tele-density at 46.73%4 limits MSS reach; GSAT-11 targets improved broadband in rural and coastal Andhra Pradesh. This aims to bridge digital divides and support inclusive growth.

Technological and Social Impact
•

Telemedicine and Social Inclusion

MSS enables telemedicine linking remote Andhra Pradesh hospitals to urban centres, reducing healthcare disparities. Partnerships with the National Health Resource Repository (NHRR) enhance these services.

•

Environmental Monitoring

Remote sensing aids forest and water resource management in ecologically sensitive zones like the Eastern Ghats. It also supports agricultural advisories and soil health monitoring, boosting sustainability.

Way Forward
•

Boost Indigenous Satellites

Enhance ISRO’s development of cost-effective MSS satellites for rural and coastal needs in Andhra Pradesh.

•

Integrate Satellite Data

Use satellite data in schemes like AIBP and IWMP for better water and agricultural management. Strengthening skilled workforce development is also essential for effective implementation.

Conclusion
Strengthening MSS and environmental monitoring through technology and policy will drive sustainable development and resilience in India.
