Q1. Consider the following statements: 1. In November, 2006 DRDO successfully conducted the interception test using the Prithvi-II missile. 2. Prithivi-II is a surface-to-surface missile and can be deployed to guard the metros against air attacks. Which of the statements given above is/are correct?
Explanation
Statement 1 is correct: In November 2006, the Defence Research and Development Organisation (DRDO) of India conducted a successful test of the Prithvi Air Defence (PAD) system, which used the Prithvi-II missile as an interceptor to destroy an incoming target missile. The Prithvi-II missile has been instrumental in validating India’s BMD technologies, ensuring readiness to protect against ballistic missile threats. This test marked a significant milestone in India’s ballistic missile defence program.
Statement 2 is correct: While the primary role of the Prithvi-II is as a surface-to-surface missile but it has been adapted for air defense purposes also. It is part of India’s Ballistic Missile Defense (BMD) system, which is designed to protect major cities from ballistic missile attacks.

Q2. What is the Galileo Project which has been in the news recently?
Explanation
The Galileo Project is a multi-satellite navigation system being developed by the European Union (EU). Galileo consists of 24 satellites orbiting Earth at an altitude of 23,000 km. The signals of Galileo are freely transmitted to anyone who has a device capable of receiving its signals (e.g., smartphone). Galileo is four times more accurate than GPS providing 1 meter accuracy and a broad range of services. It is designed to provide an independent global positioning system (GPS) for civilian and commercial use, reducing reliance on GPS systems controlled by other countries, such as the United States. Galileo aims to offer highly accurate and reliable positioning and timing information worldwide, supporting applications in transportation, telecommunications, and other critical sectors.
