The Indian Space Research Organization (ISRO) has developed a regional satellite navigation system called the Indian Regional Navigation Satellite System (IRNSS) to meet the user requirements of the positioning, navigation, and timing services based on the indigenous system.

Indian Regional Navigation Satellite System (IRNSS): NavIC

The IRNSS was renamed as “NavIC” (Navigation with Indian Constellation) by the India’s Honourable Prime Minister, Mr. Narendra Modi. Its objective is to provide precise geospatial position information service to users in India (less than 10 m accuracy) as well as covering a distance of about 1500 kms across India with better accuracy than 20 m.

Basically, two types of services will be provided by IRNSS.

  1. Standard Positioning Service (SPS): To provide services to all the users of the coverage area.

2. Restricted Service (RS): It is an encrypted service that will be provided only to the authorized users.

Applications of NavIC:

  • Terrestrial, Aerial and Marine Navigation
  • Disaster Management
  • Vehicle tracking and fleet management
  • Integration with mobile phones
  • Precise Timing
  • Mapping and Geodetic data capture
  • Terrestrial navigation aid for hikers and travellers
  • Visual and voice navigation for drivers

Service Area of IRNSS (NavIC)

NavIC service area includes India and 1500 kilometres around the Indian boundary; the extended service may also be obtained over a region lying between 30 S to 50 N Latitude and 30 E to 130 E (Source: ISRO/ S. Dan et. al., 2020).

Segment of NavIC (IRNSS), ISRO

  1. Space Segment of NavIC: 3 of the 7 satellites are geostationary orbit (GEOs) and they are located at 32.5º East, 83º East and 131.5º East longitude. There are 4 geostationary satellites (GSO) in orbits of 24,000 km apogee and 250 km perigee inclined at 29 degrees.
  2. Ground Segment of NavIC:
  • ISRO Navigation Centre
  • IRNSS Spacecraft Control Facility
  • IRNSS Range and Integrity Monitoring Stations
  • IRNSS Network Timing Centre
  • IRNSS CDMA Ranging Stations
  • Laser Ranging Stations
  • Data Communication Network

ISRO assist chipmaker to enable Indian GPS, NavIC (IRNSS) system in launch of compatible mobile chipset

ISRO has provided consultation for Qualcomm towards enabling NavIC capability in their Snapdragon mobile chipset. These chipsets are being released by Qualcomm Technologies, Inc. Which will support India’s own navigation system NavIC (IRNSS) like the US Global Positioning System (GPS). It will accelerate the adoption of NavIC by smartphone original equipment manufacturers (OEMs).

“The OEMs can now release any new models for Indian market which are NavIC enabled, thus eventually making NavIC as a standard feature in the upcoming handsets, applications, processors, etc. It will also enhance the geolocation capabilities of smartphones within the coverage region of NavIC.” (Source: ISRO dt. Jan 21, 2020).

Qualcomm Technologies, Inc. announced the launch of three new mobile platforms: The Qualcomm® Snapdragon™ 720G, 662 and 460. These new mobile platforms enable the first system-on-chip solutions to support Navigation with Indian Constellation (NavIC).

“ISRO urge OEMs to leverage it for future handset launches in India. The availability of NavIC across multiple mobile platforms will help enhance the geolocation capabilities of smartphones in the region and bring the benefits of this indigenous solution to Indian consumers for their day-to-day use” (Source: ISRO dt. Jan 21, 2020 & Qualcomm Technologies).
