PSLV-C32 Successfully Launches India's Sixth Navigation Satellite IRNSS-1F

Thursday, March 10, 2016

Bangalore: In its thirty fourth flight (PSLV-C32), ISRO's Polar Satellite Launch
Vehicle successfully launched the 1425 kg IRNSS-1F, the sixth satellite in
the Indian Regional Navigation Satellite System (IRNSS) today afternoon
(March 10, 2016) from Satish Dhawan Space Centre SHAR, Sriharikota. This
is the thirty third consecutively successful mission of PSLV and the
twelfth in its 'XL' configuration.

After PSLV-C32 lift-off at 1601 hrs (4:01 pm) IST from the Second Launch
Pad with the ignition of the first stage, the subsequent important flight
events, namely, strap-on ignitions and separations, first stage
separation, second stage ignition, heat-shield separation, second stage
separation, third stage ignition and separation, fourth stage ignition and
satellite injection, took place as planned. After a flight of 19 minutes
34 seconds, IRNSS-1F Satellite was injected to an elliptical orbit of 284
km X 20,719 km inclined at an angle of 17.866 degree to the equator (very
close to the intended orbit) and successfully separated from the PSLV
fourth stage. After separation, the solar panels of IRNSS-1F were deployed
automatically. ISRO's Master Control Facility (MCF at Hassan, Karnataka)
took over the control of the satellite.
In the coming days, four orbit manoeuvres will be conducted from MCF to
position the satellite in the Geostationary Orbit at 32.5 deg East
longitude.

IRNSS-1F is the sixth of the seven satellites constituting the space
segment of the Indian Regional Navigation Satellite System. IRNSS-1A, 1B,
1C, ID and IE, the first five satellites of the constellation, were
successfully launched by PSLV on July 02, 2013, April 04, 2014, October
16, 2014, March 28, 2015 and January 20, 2016 respectively. All the
five satellites are functioning satisfactorily from their designated
orbital positions.

IRNSS is an independent regional navigation satellite system designed to
provide position information in the Indian region and 1500 km around the
Indian mainland. IRNSS would provide two types of services, namely,
Standard Positioning Services (SPS) - provided to all users - and
Restricted Services (RS), provided to authorised users.

A number of ground stations responsible for the generation and
transmission of navigation parameters, satellite ranging and monitoring,
etc., have been established in eighteen locations across the country.
IRNSS-1G, the remaining satellite of this constellation, is scheduled to
be launched by PSLV in April 2016, thereby completing the IRNSS
constellation.
