PSLV-C45 successfully injects 28 other satellites too.
In the first of its kind, EMISAT, a satellite meant to provide intelligence to the armed forces, was launched from the Sriharikota spaceport by the Indian Space Research Organisation (ISRO) on Monday.

PSLV to launch military’s eye in the sky
''Today, PSLV-C45 successfully injected EMISAT in a 748-km orbit and 28 other satellites in a 504-km orbit as sought by the customers," ISRO Chairman K. Sivan said.
The four-stage PSLV (Polar Satellite Launch Vehicle) was launched at 9.27 a.m. from the second launch pad.
EMISAT, with its core payload or brain coming from the Defence Research and Development Organisation (DRDO), was released first into its planned slot from the fourth stage or PS4, 17 minutes into the launch.
Thereafter, the mission team fired the fourth stage — still carrying the other satellites — twice to bring it down to 504 km from the Earth.
New PSLV variant
A new fourth variant of the launcher, called the QL, was used in this mission. Its first stage was fitted (or 'strapped on') with two additional rockets.
ISRO scientists, who were broadcasting the launch live, said, "Collision avoidance analysis [or scanning the flight path for any debris that cripples space missions] is a standard practice before all launches from Sriharikota. A few earlier launches were adjusted between 30 seconds to 2 minutes, as we did for PSLV-C42 and PSLV-C43. However there was no such concern for today's mission."

At this point, PS4 released the 28 customer payloads of four countries, within five minutes. However, the entire exercise took an hour and 50 minutes since the rocket took off.
Reuse of PS4
ISRO has started reusing PS4 as an innovated, low-cost, space-friendly test bed for its own microgravity experiments and those of others. It has been gradually putting additional support systems also on every new PS4; the power generating solar panels are new this time. This is the third such mission.
The PS4-fourth stage hosts three payloads in this mission. It carries an ISRO test of Automatic Identification System (AIS) related to tracking ships on sea.
AMSAT, or the Radio Amateur Satellite Corporation, India, has sent a payload called the Automatic Packet Repeating System. This is expected to help amateur radio operators to get improved locational accuracy in their tracking and monitoring activity.
The third one, the Advanced Retarding Potential Analyser for Ionospheric Studies, has been sent up by ISRO's university, the Indian Institute of Space Science and Technology.
The other 28 international satellites are 25 3U type, two 6U type and one 2U type nano satellites. They are from Lithuania (two), Spain (1), Switzerland (1) and the United States (24).
All these satellites are being launched under commercial arrangements, ISRO said.

It looks like the launch has both commercial and military purposes. Very well done by ISRO.ISRO launches EMISAT, meant to provide intelligence to armed forces

Many US groups had demanded banning ISRO for US companies' satellites launches but still big numbers of US satellites coming to India for launch. Nice to see this.
This mission was very special and launched total 29 satellites in 3 different orbits and lasted for almost 2 Hours.
EMISAT was in making for last 8 years by DRDO and ISRO. It will be able to map all electromagnetic and communication devices of enemies in a large geographical area. It will be able to intercept enemy communication.

Blame the vodka supply. It was all Russians behind the scenes. The Indians only applied a tri-color paint job.

PSLV-C45 successfully launches EMISAT and 28 customer satellites
India’s Polar Satellite Launch Vehicle (PSLV-C45) today successfully launched EMISAT and 28 international customer satellites from Satish Dhawan Space Centre (SDSC) SHAR in Sriharikota. This flight marked the first mission of PSLV-QL, a new variant of PSLV with four strap-on motors.
PSLV-C45 lifted off at 9:27 Hrs (IST) from the Second Launch Pad and injected India’s EMISAT into a 748 km sun-synchronous polar orbit, 17 minutes and 12 seconds after lift-off. After separation, the two solar arrays of EMISAT were deployed automatically and the ISRO Telemetry Tracking and Command Network at Bengaluru assumed control of the satellite. In the coming days, the satellite will be brought to its final operational configuration.
Following the separation of EMISAT, the vehicle’s fourth stage engines were restarted twice to place the 28 international customer satellites precisely into a sun-synchronous orbit of 504 km height. The last customer satellite was placed into its designated orbit1 hour and 55 minutes after lift-off.
About 3 hours after lift-off, the fourth stage (PS4) of the vehicle was moved to a lower circular orbit of 485 km after two restarts to establish it as an orbital platform for carrying out experiments with its three payloads.
EMISAT is a satellite built around ISRO’s Mini Satellite-2 bus weighing about 436 kg. The satellite is intended for electromagnetic spectrum measurement.
The 28 international customer satellites, together weighing about 220 kg, are from four countries, namely, Lithuania (2), Spain (1), Switzerland (1) and USA (24). These foreign satellites were launched as part of commercial arrangements.
The payloads carried by PS4 are Automatic Identification System from ISRO, Automatic Packet Repeating System from AMSAT, India and Advanced Retarding Potential Analyzer for ionospheric studies from Indian Institute of Space Science and Technology.
ISRO Chairman Dr K Sivan congratulated the launch vehicle and satellite teams involved in the mission.
“Today’s PSLV mission was unique in several ways. It was a four strap-on new variant, the vehicle achieved three different orbits and for the first the PS4 stage is powered by solar panels,” Dr Sivan said. He added that a new PSLV team executed today’s mission.
Dr Sivan also placed on record the significant involvement of the industry in this mission.
So far, PSLV has launched 46 national satellites, 10 satellites built by students from Indian Universities and 297 international customer satellites, including the satellites launched today.
In its next mission, PSLV-C46 will launch RISAT-2B in May 2019.
