‘Desi’ GPS module, which we are always hearing about from last year, is finally a reality. In a program in New Delhi, MobileTek and Ram Krishna Electro Pvt. Ltd. introduced UTRAQ, a VTS module which is based on the India Regional Navigation Satellite System (IRNSS) to track the locations. Up to now, GPS-based applications in devices were based on feed given by US satellites, but UTRQ will be based on India’s own satellite system, providing more accurate and reliable location data.
There are two launches module. These include the L10GNSS module, which is a compact NaVIC module, while the L100GNSS module is a small size POT (patch at top) IRNSS module. These modules can be used for various tasks except for tracking. They include limits, commands, controls, time and more.
This means that the module can be used for marine navigation, air navigation, hikers and terrestrial navigation for passengers, vehicle tracking, and geographical data capture among others. The module will be initially given as a sample of participants and it may take some time to reach consumer products.
Unaware of those people, immediately after the Kargil War in 1999, pressure was made to create ‘Desi’ VTS module (which is part of IRNSS) for services and equipment, when Pakistan troops took over in Kargil. At that time, India had handled GPS location data only with US satellites to face a denial. GPS-based data by the US has given some important information, which will help India to control the damage. Now, with IRRQ, which is based on IRNSS, which is controlled by the Indian Space Research Organization (ISRO), the systems will be able to see more accurate data without reliance on foreign satellites.
It is being said that IRNSS (which is based on UTQQ) is said to provide status for the Indian territory of 1500 km of Indian Area as the primary service area. It has also been mentioned that the extended service area will be between primary service area and latitude 300 south to 500 north and longitude between 300 east to 1300 east zone.
UTRQ module L1 and L5 band, EPOTM prediction, EASVTM predicts self generated pocket and measures 18x16x2.3 mm. Coming back to IRNSS, this navigation system provides positioning data of region that extends 1500 km from India’s mainland (including mainland, of course). This area is called the Primary Service Area. There’s also an Extended Service Area that lies between the Primary Service Area and the area enclosed by the rectangle from Latitude 30-degree South to 50-degree North and Longitude 30-degree East to 130-degree East.
Following are some of the applications of IRNSS:
- 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
The constellation of IRNSS consists of seven satellites – three of which are located in geostationary orbit (GE)O), with the other four located in inclined geosynchronous orbit (GSO). IRNSS also provides two types of services – Standard Positioning Service (SPS) and Restricted Service (RS). SPS is provided to all the users and has accuracy of up to 10 meters, whereas, RS is an encrypted service and is only provided to authorized users – including military.
