ISRO to Launch Defence Satellite in March For DRDO

In a special mission in March, the Indian space agency will launch an electronic intelligence satellite Emisat for the DRDO, 28 third party satellites and also demonstrate its new technologies like three different orbits with a new variant of Polar Satellite Launch Vehicle (PSLV) rocket, said a top official. The exact date has not been specified yet.

"It is a special mission for us. We will be using a PSLV rocket with four strap-on motors. Further, for the first time we will be trying to orbit the rocket at three different altitudes," K. Sivan, Chairman, Indian Space Research Organisation (ISRO) told IANS. "The main passenger for the PSLV rocket will be the defence intelligence satellite Emisat belonging to Defence Research and Development Organisation (DRDO).

"The satellite weighs about 420 kg. The 28 satellites belonging to our customers would cumulatively weigh about 250 kg," Sivan said. The DRDO's Emisat is an electronic intelligence satellite, he added. The ISRO will also be launching two more defence satellites sometime in July/August with its new rocket Small Satellite Launch Vehicle (SSLV).

In January, the space agency launched a defence imaging satellite Microsat R for the DRDO. Sivan said, after launching Emisat at an altitude of 763 km, the rocket will be brought down to put into orbit the 28 satellites at an altitude of 504 km. "Following that the rocket will be brought down further to 485 km where the fourth stage will turn into a payload platform carrying three experimental payloads -- one developed by the students of Indian Institute of Space Science and Tecnology, besides ISRO's own technology demonstrator and a Hamsat," Sivan said.

The PSLV is a four-stage engine expendable rocket with alternating solid and liquid fuel. In its normal configuration, the rocket will have six strap-on motors hugging the rocket's first stage. On January 24, the ISRO flew a PSLV with two strap-on motors while in March it will have four strap-on motors. The Indian space agency also has two more PSLV variants viz Core Alone (without any strap-on motors) and PSLV-XL a larger rocket. The ISRO selects the kind of rocket to be used based on the weight of satellites it carries.

Not really. Unlike WU-14, HSTDV is a powered vehicle with SCRAMJET. WU-14 is comparable to Avangrad and HSTDV is comparable to Zircon.
I thought that Wu-14 was a scramjet powered vehicle!!! If not Wu-14, then what is the Chinese project to master Scramjet technology for military application?

Thats a hatch . The tugs are about to tow the ship out for trials. The initial phase of sea trial.
If you note carefully the hatch is being held in position by a crisscross triangular grid.

If it was a hatch , then we would have seen only 2 hydraulic arms at the either sides of the hatch to raise or lower it.

I believe it's a sort of troposcatter over the horizon ( OTH) passive radar on a rotating mount.

The primary radar ( in the big dome ) is the MOTR radar which is basically a look up radar. IE it searches and detects targets in air / near space.

However to scan the earths surface at long distances ( to negate the constraints of radar horizon ) a surface search radar is needed which is where the troposcatter over the horizon ( OTH) passive radar comes into play.

The thing in the pic looks like this, kind of.

Disclaimer : it's only my speculation to the best of my knowledge , so best wait for official confirmation .

HAL LCH was supposed to get IOC for TD-4 by the end of 2018. Did it get IOc or dates were extended?

BEL to make helmet-mounted display system


BENGALURU: State-run Bharat Electronics Ltd (BEL) on Tuesday said it will make helmet-mounted display system for military pilots with Israeli firm Elbit System Ltd.

"We have signed an agreement with Elbit to make helmet-mounted display system and helmet-pointing system under licence for Indian Naval and rotary wing platforms of the armed forces," said the city-based defence firm in a statement here.

BEL Marketing Director Anandi Ramalingam and Elbit Vice President for business development Avi Mizrachi signed the agreement in the presence of BEL Chairman M.V. Gowtama and Elbit Chief Executive B. Machilis.

"Under the agreement, BEL will make and integrate the system with night-flying vision goggles, colour day & night display, 3D symbology, head-tracking, sensors and weapon cuing," said the company statement.

The system displays helicopter's flight and platform information, mission data, target information and enhanced application capabilities such as low visibility landing and take-off, flight within degraded visibility environment, optional weapons management and synthetic vision during day and night flying.

The 'heads up, eyes out' concept minimises the need for 'heads down' in-cockpit instrumentation observation for critical information as altitude, velocity, engine performance, warning indications and allows the crew to concentrate on mission performance, thus increasing situational awareness and survivability in all missions, it said.
