ISRO to develop replacement GPS for better accuracy

Kolkata: India’s indigenous position determination system being developed by national space agency ISRO will serve as a “replacement GPS” for the public with enhanced access in remote areas, an official said here on Saturday.

It will also aid in navigation and monitoring of fleet (trucks and ships) movement, the official added.

“We will have our own position determination system using our own navigation constellation, the IRNSS series which will be operational by middle of next year. It is a kind of replacement GPS,” said Deviprasad Karnik, the director, publication and public relations, ISRO.

“The US is offering the GPS navigation. IRNSS is indigenous”, he added while talking to reporters here on the sidelines of a lecture on India’s Space mission and use of Space Technology as a solution to Sustainable challenges of Kolkata at Birla Industrial and Technological Museum.

Four of the seven satellites in IRNSS constellation (IRNSS-1A, 1B, 1C, and 1D) are in orbit. Remaining three satellites (IRNSS-1E, 1F and 1G) are targeted for launch during January 2016 to March 2016, he said.

“Once the constellation is completed, we need some time to establish the accuracy part, validation and other things. The advantage is that the navigation range has been designed to span around 1,500 km radius around India,” he said.

“GPS is not available at all places. Signal is weak in remote areas but our own signal will be available in remote areas with better accuracy.”

As an example of the app-based positioning service, Karnik said, it will help in effective management of fleet movement.

“Monitoring and effective management of fleet of trucks or ship monitoring will be done through spacecraft. For example, for ships the system can inform which route will be more effective. That will save time and fuel,” he said.

Chennai-based Space Kidz India plans to build a satellite – Vikramsat – to do some biological experiment in space, said a top official.

She also said her dream of putting a satellite built by students will become a reality on January 24 night when an Indian rocket Polar Satellite Launch Vehicle (PSLV) will carry a small communication satellite Kalamsat.

“We are planning to build a satellite called Vikramsat to do some biological experiment in the space. By this we hope to contribute in a small way to India’s ambitious human space mission Gaganyaan,” Srimathy Kesan, Founder CEO of Space Kidz India, told IANS.

Speaking about the nano-satellite Kalamsat, she said it was a 10cm cube, 1.2 kg communication satellite with a life span of two months. The satellite cost was about Rs.12 lakh.

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

Space Kidz India is working towards promoting art, science and culture for students of India, create an international platform for them.

India will open its 2019 space programme account on January 24 night by launching imaging satellite Microsat-R for the Defence Research Development Organisation (DRDO) and Kalamsat.

The satellites will be carried by a new variant of India’s Polar Satellite Launch Vehicle (PSLV) rocket.

“We will be launching 700-kg Microsat-R and Kalamsat with a new variant of Polar Satellite Launch Vehicle (PSLV). In order to reduce the weight and increase the mass, an aluminum tank is used for the first time in the fourth stage,” K. Sivan, Chairman of Indian Space Research Organisation (ISRO), told IANS.

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.

However, the PSLV that would fly on January 24 with Microsat R and Kalamsat will be a two strap-on motors configuration and is designated as PSLV-DL.

The Indian space agency is planning to have the launch at about 11.40 p.m. on January 24.

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

Space Kidz India’s Kesan is a happy woman as Kalamsat will be entering the history books on that account. (IANS)
