On 1 April India Launch Electronic Intelligence Satellite And First Time Demonstrate Three Different Orbits

According to ISRO, on 1 April India will launch an electronic intelligence satellite Emisat for the Defence Research Development Organization (DRDO) along with 28 third party satellites said on Saturday. It also demonstrate its new technologies such as three different orbits with a new variant of PSLV rocket.

According to (ISRO), a new variant of its Polar Satellite Launch Vehicle (PSLV) rocket will first put the 436 kg Emisat into a 749 km orbit. And After that, the rocket will be brought down to put the orbit into 28 satellites at an altitude of 504 km.

This will be tailed by bringing the rocket down added to 485 km when the fourth stage/engine will turn into a payload platform. For the structural and compositional studies of ionosphere, the space agency said, this carrying three experimental payloads: 1) Automatic Identification System (AIS) from ISRO for Maritime satellite applications capturing messages transmitted from ships 2) Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India – to assist amateur radio operators in tracking and monitoring position data and 3) Advanced Retarding Potential Analyser for Ionospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST).

On April 1 the whole flight sequence will take about 180 minutes from the rocket’s lift off slated at 9.30 a.m.

The 28 international customer satellites in that 24 from US, 2 from Lithuania and one each from Spain and Switzerland will weigh about 220 kg.

“For us it is a special mission. We will be using a PSLV rocket with four strap-on motors. In addition, ISRO Chairman K. Sivan had earlier told IANS, for the first time we will be trying to orbit the rocket at three different altitudes.”

On January 24, the ISRO flew a PSLV with two strap-on motors while in March, it had four strap-on motors. Further, the Indian space agency also has two more PSLV variants, such as Core Alone (without any strap-on motors) and the larger PSLV-XL.

The ISRO selects a kind of rocket to be used based on the weight of satellites it carries.

The ISRO will also be launching two more defence satellites sometime in July or August with its new rocket Small Satellite Launch Vehicle (SSLV).
