The Indian government has invited proposals for the manufacture of 10 lakh receiver chips that have GPS and NavIC, in an attempt to improve the overall signal availability of positioning systems, and increase the use of the indigenous positioning system.
In a bid titled, “Request for Proposal Design, Manufacture, Supply and Maintain Integrated NavIC and GPS Receivers,” the ministry has stated it wishes to use the NavIC integrated receivers for areas such as navigation on land, air and water, disaster management, vehicle tracking, location services on mobile phones.
With NavIC, the government is keen to promote an “indigenous positioning technology,” one that is “totally under Indian control,” the RFP states.
WHAT IS NavIC?
Indian Regional Navigation Satellite System (IRNSS) named as NavIC is ISRO’s initiative to build an independent and regional satellite navigation system based on a constellation of seven GEO and GSO satellites.
The satellites are placed in two different orbital planes; three satellites in the Geostationary orbit (GEO) and four satellites in the Geosynchronous orbit (GSO) with an inclination of 29º.
The RFP states that NavIC “provides accurate position information service to users in India as well as the region extending up to 1500 km from its boundary of India.”
WHAT ARE THE APPLICATIONS OF NavIC?
IRNSS will provide two types of services:
The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area.
WHAT CAN NavIC BE USED FOR?
According to ISRO, NavIC finds usage in a range of activities such as:
HOW IS NavIC DIFFERENT FROM GPS?
While the GPS is maintained by the US government, NavIC is an indigenous system developed and maintained by the Indian government.
NavIC has been designed to provide accurate position information to users within India. “It will help India enter the club of select countries which have their own positioning systems,” an Economic Times report had stated in 2018.
“A need for an indigenous satellite navigation system was felt earlier, but the Kargil experience made the nation realise its inevitability,” the Economic Times report stated.
Besides America’s GPS (with 24 satellites in a constellation), Russia has its GLONASS and European Union its Galileo. Interestingly, China is also in the process of building Beidou Navigation Satellite System.
Integrated NavIC and GPS receiver chip will improve overall signal availability and position accuracy in urban areas and will also support additional messaging facility, unlike GPS-only receiver chips.
WHAT DOES THE TENDER RFP SAY
According to the proposal document issued by MeitY, “Government of India envisages commercialisation of NavIC user receivers to promote an indigenous positioning technology.”
The winning bidder is required to design, manufacture, supply and maintain 10 lakh Integrated NavIC and GPS receivers; and ensure deployment of Integrated NavIC and GPS receivers.
All bidders will have to submit an Earnest Money Deposit (EMD) of Rs 1 crore.
