Identifying India's Communication Satellite Launched in November 2015

The question asks us to identify the specific communication satellite launched by India in November 2015 from the given options. India has an active space program, primarily managed by ISRO (Indian Space Research Organisation), which regularly launches satellites for various purposes, including communication.

Communication satellites are placed in geostationary orbit to provide continuous coverage over a specific region. India's primary series of geostationary communication satellites is the GSAT series.

Analyzing the Launch Dates of Satellites in Options

Let's examine the launch dates and types of the satellites listed in the options:

• GSAT-6: This is a communication satellite. It was launched by ISRO on August 27, 2015. This date is close to, but not exactly, November 2015.
• GSAT-15: This is a communication satellite. It was successfully launched by ISRO using the Ariane 5 rocket from Kourou, French Guiana, on November 11, 2015. This date perfectly matches the timeframe mentioned in the question.
• GSAT-16: This is a communication satellite. It was launched on December 7, 2014. This is earlier than November 2015.
• IRNSS-1E: IRNSS satellites are part of the Indian Regional Navigation Satellite System, which is for navigation services, not primarily communication. IRNSS-1E was launched on January 20, 2016. This is later than November 2015 and is a navigation satellite, not a communication one.

Conclusion on the November 2015 Launch

Based on the launch dates and the type of satellite, GSAT-15 is the communication satellite that was launched by India in November 2015. It was intended to provide communication services, including supporting satellite navigation signals.

Therefore, the communication satellite launched by India in November 2015 is GSAT-15.

Additional Information on GSAT Satellites and ISRO

ISRO's GSAT series satellites are a significant component of India's space infrastructure, providing essential services. These include:

• Television broadcasting
• Telecommunications (phone and internet)
• Broadband services
• Disaster management support

ISRO continually develops and launches new satellites to meet the growing demands for communication services across the country. The IRNSS system, known as NavIC (Navigation with Indian Constellation), is India's independent navigation satellite system, similar to GPS but focusing on the Indian region.
