The countdown for the flight Thursday night of an Indian rocket carrying the Microsat R imaging satellite of the Defence Research and Development Organisation (DRDO) and the Kalamsat student satellite will begin later on Wednesday, an Indian space agency official said.

“The countdown for the PSLV (Polar Satellite Launch Vehicle) rocket launch will start today (Wednesday).

“The countdown duration and its starting time, the time of rocket launch would be announced later,” an official of the Indian Space Research Organisation (ISRO) told IANS.

The rocket launch was expected to happen at about 11.40 p.m. on Thursday.

“We will be launching the 700-kg Microsat R and Kalamsat with a new PSLV variant.

“To reduce weight and increase the mass, an aluminium tank is being used for the first time in the fourth stage,” ISRO Chairman K. Sivan had told IANS earlier.

He said Kalamsat is a payload developed by students and Chennai-based Space Kidz India.

The PSLV is a four-stage engine expendable rocket with alternating solid and liquid fuel.

In its normal configuration, the rocket would have six strap-on motors hugging the its first stage. However, the PSLV that would be flying on January 24 with Microsat R and Kalamsat will be a two strap-on motors configuration and is designated as PSLV-DL.

The rocket PSLV-C44 is the first mission of PSLV-DL and is a new variant.

About 14 minutes into the flight the rocket would eject Microsat R at an altitude of about 277km. This would start functioning at an altitude of 450km in about the 103th minute after lift-off.

The Kalamsat would be the first to use the rocket’s fourth stage as an orbital platform. The fourth stage would be moved to higher circular orbit so as to establish an orbital platform for carrying out experiments, ISRO had said.

“The Kalamsat is a 10cm cube nano-satellite weighing about 1.2kg. The satellite’s life span is about two months and its cost is about Rs 12 lakh,” Srimathy Kesan, Founder-CEO of Space Kidz India, told IANS.

Space Kidz India is working towards promoting art, science and culture for students in India.

According to Kesan, Kalamsat will be the first satellite of Space Kidz India to be in a proper orbit as its earlier satellites were suborbital ones. (IANS)

Chinese handset maker Realme and South Korean major Samsung have the lowest return rates among all smartphone brands in India, a survey by CyberMedia Research (CMR) said on Thursday.

The “CMR MICI” survey that included 4,000 smartphone owners across top eight Indian cities, focused on smartphone purchase process, key smartphone specs of priority, as well as issues with post-sales service, including repairs or replacements.

“The return rates in smartphone brands provide a measure of consumer satisfaction with their current brand and, in turn, implies that the brands have been able to excel in meeting consumer expectations. Our survey findings report the lowest return rate for brands, such as Realme and Samsung, in comparison to the prevailing industry average,” Prabhu Ram, Head-Industry Intelligence Group (IIG), CMR, said in a statement.

The lowest return rates are determined by the first visit to the brand’s service centre within the first six months of purchase, for either repair or replacement, by both online as well as offline buyers.

Around three per cent of the total smartphone users visited a service centre for the first time within the first six months of their smartphone purchase, during the in-warranty period.

When it comes to looks, design and feel, users of Vivo are most satisfied (99 per cent), followed by OPPO and Realme users (98 per cent each), and at third place, Xiaomi with 97 per cent satisfaction.

Across smartphone brands, users are excited about the design aesthetics, camera performance and build quality that phones sport across price bands.

Users indicated more satisfaction with intangible factors that they associate with their smartphones, including reliability and performance.

“In order to win consumer mindset, smartphone brands need to invest in getting not just product design and product quality right, but they must ensure overall brand experience, and service quality right,” Ram added.
