The year 2016 was very eventful for the Indian space programme which scored very prominent and significant successes in launch vehicle, satellite, applications and space exploration domains. The year saw an unprecedented seven launch vehicle missions all of which were successful. Eight ISRO satellites, four student satellites and 22 foreign satellites were launched by these missions. The year 2016 also saw two successful advanced launch vehicle technology initiatives of ISRO - the Reusable Launch Vehicle-Technology Demonstrator (RLV-TD) and SCRAMJET technology demonstrator - which had their maiden test flights. Additionally, the highly successful Mars Orbiter Spacecraft of India completed two years in its orbit around Mars and India's ASTROSAT multi-wavelength observatory successfully completed one year in orbit.

Launch Vehicle and Satellite Missions of ISRO:

 

1.1. PSLV-C31/IRNSS-1E Mission: In this flight, the workhorse launch vehicle PSLV launched IRNSS-1E, the fifth satellite of the Indian Regional Navigational Satellite System (IRNSS) constellation, on January 20, 2016.

1.2. PSLV-C32/IRNSS-1F Mission: In this flight, which was its 34th, PSLV launched IRNSS-1F, the sixth satellite of the Indian Regional Navigational Satellite System (IRNSS) constellation, on March 10, 2016.

1.3. PSLV-C33/IRNSS-1G Mission: In this flight, PSLV launched the seventh and the last satellite IRNSS-1G of the Indian Regional Navigational Satellite System (IRNSS) constellation on April 28, 2016. With this, the space segment of the IRNSS is fully deployed. IRNSS signals are now available and trials with the receiver system are in progress. The Prime Minister Shri Narendra Modi dedicated IRNSS to the nation as 'NavIC' (Navigation Indian Constellation). This is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland. IRNSS provides two types of services, namely, Standard Positioning Services (SPS) - provided to all users and Restricted Services (RS) - provided to authorised users only.

1.4. Reusable Launch Vehicle - Technology Demonstrator (RLV-TD): India's first winged body aerospace vehicle, RLV-TD i.e. Reusable Launch Vehicle-Technology Demonstrator (RLV-TD), was successfully flight tested on May 23, 2016. From the peak altitude of 65 km, RLV-TD began its descent followed by atmospheric re-entry at around Mach 5 (five times the speed of sound). After successfully surviving a high temperature of re-entry, RLV-TD successfully glided down to the defined landing spot over Bay of Bengal. In this flight, critical technologies such as autonomous navigation, guidance & control, reusable thermal protection system and re-entry mission management were successfully validated.

1.5. PSLV-C34/Cartosat-2 Series Mission: On June 22, 2016, PSLV-C34 successfully launched 20 satellites in a single mission. It included India's CARTOSAT-2 series of satellite (weighing 727 kg) as primary payload and two academic institutes' satellites, namely, SWAYAM and SATHYABAMASAT and 17 satellites (total weighing 555 kg) of foreign customers from Canada, Germany, Indonesia and USA as co-passengers.

1.6. GSLV-F05/ INSAT-3DR Mission: On September 08, 2016, GSLV-F05, India's Geosynchronous Satellite Launch Vehicle, equipped with the indigenous Cryogenic Upper Stage (CUS), successfully launched the country's weather satellite INSAT-3DR. INSAT-3DR is a follow-on meteorological satellite to INSAT-3D. This launch is significant, considering that fact that this is the third consecutive success of the indigenous CUS, which signified the country's successful assimilation of the complex cryogenic rocket propulsion.

The satellite carries two meteorological payloads, viz., 6 channel imager & 19 channel sounder. It also carries a Data Relay Transponder (DRT) and Satellite Aided Search and Rescue (SA&R) payload to provide continuity to INSAT SA&R services. The satellite has started providing services to the weather and meteorological community in tandem with INSAT 3D that is already in the orbit. By virtue of these 2 satellites in orbit, the country gets weather updates every 15 minutes which is yet another unique service from space.

1.7. Successful Flight Testing of ISRO's Scramjet Engine Technology Demonstrator: The first experimental mission of ISRO's Scramjet Engine towards the realisation of an Air Breathing Propulsion System was successfully conducted on August 28, 2016 from Satish Dhawan Space Centre SHAR, Sriharikota. The Scramjet engine designed by ISRO uses Hydrogen as fuel and the Oxygen from the atmospheric air as the oxidiser. This marked the maiden short duration experimental test of ISRO's Scramjet engine with a hypersonic flight at Mach 6. ISRO's Advanced Technology Vehicle (ATV), which is an advanced sounding rocket, was the solid rocket booster used for the test of Scramjet engines at supersonic conditions. ATV carrying Scramjet engines weighed 3277 kg at lift-off.

India is the fourth country to demonstrate the flight testing of Scramjet Engine. The successful technology demonstration of air-breathing Scramjet engines in flight by ISRO during the year was a modest yet important milestone in its endeavour to design and develop advanced air breathing engines including engines for ISRO's future space transportation system

2. PSLV-C35/SCATSAT-1: By successfully launching SCATSAT-1 satellite carrying a scatterometer for wind vector measurement into the required polar Sun Synchronous Orbit in its PSLV-C35 mission on September 26, 2016, the PSLV facilitated continuity to Oceansat-2 Scatterometer, which completed its service in March 2014. The wind vector at sea surface information facilitated by SCATSAT-1 is used in weather prediction models and helps in accurate prediction of cyclone track. This launch of PSLV had yet another unique achievement of placing satellites in 2 different orbits and also the longest of the missions that lasted for more than 2 hrs 15 mins after lift-off. In this mission, engine multiple restart experiment of upper stage of PSLV was also demonstrated.

2.1. PSLV-C36/Resourcesat-2A: In its 38th flight, PSLV successfully launched RESOURCESAT-2A satellite on December 07, 2016 into an 822 km polar Sun Synchronous Orbit. This was PSLV's 37th consecutive success. The 1235 kg RESOURCESAT-2A is a follow on mission to Resourcesat-2 and intended to ensure data continuity to the users for land and water resources applications. The satellite is configured with three-tier imaging capability consisting of three solid-state cameras, viz., LISS-IV, LISS-III and an Advanced Wide Field Sensor (AWiFS).

2.2. GSAT-18: The 3405 kg communication satellite GSAT-18, launched on October 06, 2016 by European Ariane V, carries a total of 48 transponders in Ku-band, C-band and Ext C-band for providing continuity of services and has further augmented the transponder capacity.
