GPS is a global system that provides a position, velocity and time alignment with the global navigation satellite system.
The GPS comprises 24 satellites spanning about 12,000 miles across the surface of the world. They orbit the Earth at 7000 miles an hour once every 12 hours at a really high speed (11,200 kilometers per hour).
The satellites are uniformly distributed such that four satellites can be accessed from anywhere in the world by the direct view.

GPS is all around. In your car, tablet and watch you can find GPS systems. GPS will help you get from point A to point B where you are headed.
So what are the GPS alternatives built and for use by various countries and unions during the period? Let’s see the latest and best alternatives for GPS. Ready! Let’s Dig in!
Galileo, Europe’s proposed worldwide satellite navigation network, will offer an extremely precise and safe worldwide civil control positioning service.
To ensure GPS and Galileo are compliant and interoperable at the consumer level, the US and Europe have been collaborating since 2004.
Galileo delivers real-time positional precision to a variety of metres by delivering two frequencies as usual, which historically could not be achieved by a public system. In all but the most serious conditions,
Galileo will guarantee the service availability and notify the customers of the satellite failure in a matter of seconds. This makes it ideal for safety uses, such as air and land transport.
Galileo will provide a global Search and Rescue function (SAR) based on the Cospas-Sarsat2 operational search and rescue system. To do this, the transmission of distress signals into the Rescue Coordination Center (RCC) and the rescue operation will occur at each satellite of Galileo.
Around the same time, the device would provide the customer with a signal telling him that his situation is identified and that assistance is being provided.
NavIC is also known as the Indian Regional Satellite Navigation System (IRNSS), aiming to ensure that users of the technology can provide the most reliable and accurate position service. Eight IRNSS satellites are used to fuel it, one of which offers messaging services.
Improvements to NavIC would develop the user interface for location-based applications and increase monitoring of locations in dense urban areas where geolocation precision continues to decrease.
The space agency is partnering for NavIC’s latest processors for budgetary to mid-sized smartphones with Qualcomm, one of the world’s largest chipset firms. The plans to use NavIC-enabled processors for phones have already been verified by Xiaomi and Realme.
It allows for better location efficiency, and quicker acquisition of place from time to time (TTFF) and better quality of location-based services.
There are some more
The applications of NavIC system are:
• Navigation by air and sea
• Management of disasters
• Truck tracking and corporate fleet maintenance
• Timing enhanced
• Enhanced mapping and capture of geodetic data
• Aid for hikers and travelers to land navigation
• Driver visual and audio browsing
GLONASS is an acronym that means the Global Navigation System Sputnikovaya, a global navigation satellite system translated into Russian.
GLONASS officially operates under the Russian Aerospace Defense Forces, providing both military and civilian real-time location and speed determination. The development of GLONASS began in 1976 and was revived as a top government priority in the early 2000s.
It was finished in the Soviet Union. Today, GLONASS has a network of 24 satellites protecting not only 100% of the territories of Russia but the world as a whole with 3 orbital aircraft.
Although GLONASS has been developed as an alternative to GPS, we now see significant advantages for all systems to operate together and not independently in order to ensure an accurate location on Earth.
The integration into the GLONASS GPS of all 55 satellites worldwide produces far more precise results, especially for urban canyons. The integration into the GLONASS GPS of all 55 satellites worldwide produces far more precise results, especially for urban canyons.
The Japanese satellite navigation system, Quasi-Zenith Satellite System, is in progress. It transmits GPS-interoperable, increases signals and original Japanese signals from a sloping geosynchronous orbit.
The device allows consumers across the country, including urban canyons and mountainous areas, to use streamlined positioning, browsing and scheduling services.
A government policy promotes the initiative of using satellite-based navigation geographical knowledge for a rich, safe existence, as satellite users around the country rapidly develop.
JAXA in partnership with relevant ministries and national institutions is responsible for establishing the first phase of QZSS in favour of such a programme.
The aim of the system is not only satellite but also land systems and operational technologies to make the system stable and cost-effective by legacy Japanese GEO technology.
Based on the Chinese term of the constellation the Big Dipper, the Beidou System operates on a network of around 30 satellites, competing with the US [Global Positioning System (GPS)] [GLONASS] and Russia [Galileo], the European Union [Galileo]
In the early 1990s, China began to develop a device that could help vehicles, fishing boats and military tankers navigate the country’s satellite mapping data.
Now, millions of mobile telephones can be used to locate restaurants, gas stations or cinemas in the vicinity and to lead taxis.
Accuracy of this system can be determined as the analysts said Beidou had previously overtaken GPS with regard to precision but had a long way to go before overtaking his American opponent as the dominant geo-location device in the world.
Chinese forces would also profit from the completion of the Beidou Network. China has poured some $10 billion into the Beidou infrastructure (around Rs. 74,474 crores), to maintain the military intelligence communications networks and to prevent the possibility of disturbance.
Can you recall that it was hard to work to go to a new unknown location and often a time-consuming nightmare away from it? Remember the moment the weather was all conjectured? And the headache was to find a different direction!
The invention of GPS and its application to ordinary people made life easier, thanks to new GPS techniques that have facilitated the use of this technology and make it easy for them to fly to wherever.
