With reference to the NavIC (Navigation with Indian Constellation) system and the NVS series of satellites, consider the following statements: 1. NVS satellites introduce the L1 frequency band to improve interoperability with global positioning systems like GPS. 2. The second-generation NVS satellites exclusively use imported atomic clocks to avoid the failures seen in earlier missions. 3. NavIC provides both a Standard Positioning Service (SPS) for civilian use and a Restricted Service (RS) for authorized military users. Which of the statements given above is/are correct?

Question

C - 1 and 3 only — Statement 1 is correct as NVS satellites include the L1 band for better integration with civilian devices like smartphones. Statement 2 is incorrect because the NVS series specifically introduces indigenously developed Rubidium atomic clocks to reduce reliance on imports. Statement 3 is correct as NavIC is designed to provide both an open Standard Positioning Service and an encrypted Restricted Service.
