You Should Know This 4 GPS Alternatives
The oldest navigation system, GPS made by the US Defense, has started its journey from 1978. Gradually, according to its working efficiency, GPS became admired as a navigation system which is similar to the Global Satellite Navigation System (GNSS). There are other many navigation systems available that are made by different countries and that can be considered as great alternatives to GPS. If you not only want to stick with the navigation system, GPS, you can choose another from the list mentioned below, there you will find four GPS alternatives option.
This Year’s Top Four GPS Alternatives Are
The ‘GLONASS‘ work since 1995, that developed and run by Russia. It supports a constellation of 24 satellites in comparison to GPS’ 31 satellites, and it’s an amazing feature is similar to GPS’ 4-7 meters which is ‘GLONASS‘ has a location precision of 5-10 meters. With the help of local cellular triangulation, the location builds up to become better.
GLONASS and GPS are almost the same in terms of coverage and accuracy. One required more than 20 satellites for a global navigation satellite system to work, and since 2010, Russia has maintained the constellation.
In the European Union (on the year 2005) the another GPS alternative had started developing, and in 2016 that constellation comes to life, which called ‘Galileo‘. It is a global navigation satellite, like as GPS. Though the GPS and Galileo both are mostly the same in terms of altitude GPS a little bit good, because, Galileo sometimes suffered some issues with Automic clocks and weak signals in the past few years.
You can choose it as an alternative of GPS because in 2020 any time Galileo will be considered as another global navigation satellite system that will be going to get better after it reaches Full Operational Capability (FOC). Now, Galileo has 22 operational satellites rotating around the Earth.

Navigation with Indian Constellation or NavIC also known as Indian Regional Navigation Satellite System (IRNSS) which is built by India for its region and neighbors, starts its works from 2013. This independent regional navigation satellite system able to provide accurate position information service to users in India besides the region extending up to 1,500 km from India’s border. It supports two types of services SPS (Standard Positioning Service), and RS (Restricted Service). SPS provided to all users and RS provided to the only authorized users. NavIC is developed by ISRO.
It is true that the NavIC covers only India and some neighboring regions, where the GPS covers the whole world for location positioning, but you can’t ignore that on accuracy the NavIC is more good than the GPS. Satellites are all-time stay in direct line of sight with India’s region for the NavIC. Lastly, we can easily say that NavIC is a good alternative to GPS.
This satellite is developed by Japan. It has a constellation of four satellites, and it is closely similar to India’s NavIC. In the Japanese language, the QZSS is known as Michibiki. The QZSS has the same principle of ‘direct line of sight at all times‘ similar to the NavIC.
To make sure at least one of the satellites is visible over Japan at all times, QZSS has deployed its satellites in both geostationary and geosynchronous orbit. In 2010 Japan has stated their journey of making Quasi-Zenith and rolled out the service for public use in 2018.
GPS ALTERNATIVE SYSTEMS
The best four GPS alternative systems are in front of your eyes, which made by different countries such as Russia, the European Union, India, and Japan. Basically, they made satellite systems mainly for self-dependency from terrestrial war, serial attacks, submarine, and more. One thing you need to know that common users are not capable to choose which GNSS system they use, which all depended on the smartphone hardware and navigation apps which they using that time.
