Top 5 GPS Alternatives for Next-Generation Navigation

In this article, GPS alternatives for next-generation navigation will be discussed. It has essentially replaced it as the de facto norm, the Global Positioning System (GPS) (GNSS). The issue is aggravated by GPS, which is the earliest navigational system. The US Military launched it in 1978. However, other navigation systems exist, such as the recently disclosed NavIC by India, GLONASS, BeiDou, Galileo, and quasi-zenith. As a result, we carefully examine each GPS alternative in this essay and compare them side by side. We have already discussed a satellite navigation system’s coverage, orbital height, precision, and other features.

Here are some details about GPS substitutes for next-generation navigation that you may learn about in this article:

1. Galileo

Since most significant countries already had satellite navigation systems, the European Union developed its own GNSS. They started the project in 2005, and the Galileo constellation finally went active in 2016. Galileo is a global satellite navigation system, much like GLONASS and GPS. There are now 22 operational satellites in the constellation orbiting the Earth.

The EU aims to quadruple the number of satellites to 30 by the end of this year. Almost similar operational principles underlie GPS and Galileo. Galileo, however, is significantly higher in altitude. There is also the reality that Galileo has had some recent problems with Atomic clocks and inadequate communications. Another global satellite navigation system, Galileo, will advance until it reached Full Operational Capability (FOC) in 2020. Later, it will take the place of GPS as a reliable alternative.

2. GLONASS

Only GLONASS, a satellite navigation system, comes close to GPS regarding coverage and accuracy. Russia created and oversaw its management, which has been used since 1995. GLONASS has a constellation of 24 satellites as opposed to the 31 satellites that GPS has. Russia has maintained the constellation since 2010 when a global navigation satellite system needs to operate.

GLONASS and GPS are similar in several ways since, other than that, they both have nearly the same orbital height and period. Positional accuracy for GLONASS is between 5 and 10 metres, which is excellent and equivalent to GPS’s 4 to 7 metres. Naturally, employing local cellular triangulation greatly enhances the position. Regarding functionality, the Russian satellite navigation system GLONASS is only surpassed by GPS.

3. Quasi-Zenith

A regional satellite navigation system developed by Japan called the Quasi-Zenith Satellite System (QZSS) is strikingly similar to India’s NavIC. QZSS, also known as Michibiki in Japanese, has a constellation of four satellites. Initiated in 2010 by Japan, the service was made accessible to the general public in 2018.

Like GPS, Quasi-Zenith seeks to offer exact and trustworthy finding services in Japan and a few other Asia-Oceania locations. Despite Japan’s extremely slow satellite navigation system growth, they are committed to launching seven more satellites by 2023. Moreover, QZSS is in sync with Japan’s coordinates and follows the same “direct line of sight at all times” concept as NavIC. It has placed its satellites in geosynchronous and geostationary orbits to ensure that at least one satellite is always visible over Japan. As a result, although Japan’s QZSS is different from the US’ GPS in many ways, it exhibits great promise, and we predict additional development soon.

4. NavIC

Although NavIC is a relatively new satellite navigation technology with excellent potential. In case you didn’t know, India created the NavIC satellite navigation system exclusively for its region and neighbouring countries.

However, NavIC is a localised navigation satellite system instead of GPS, a global navigation satellite system. Essentially, it suggests that GPS covers the entire planet for geographic locating, whereas NavIC primarily serves India and portions of its neighbouring countries. However, due to the NavIC satellites’ constant line-of-sight proximity to India, NavIC is more accurate than GPS, at least there. Last but not least, NavIC is an Indian autonomous satellite navigation system that fares better than GPS. The fact that India will launch at least five more satellites in the following years is also significant.

5. BeiDou

Like GPS, China manages the global satellite navigation system, BeiDou. To make a GPS replacement for its clients, the project was initially launched in 2000. Nevertheless, there were only two satellites, which resulted in extremely poor coverage and inaccurate precision. In 2012 and 2015, respectively, China expanded the constellation by launching 10 and 15 satellites into Earth’s orbit. The total number of active satellites in the constellation now stands at 33 after China launched seven more satellites since 2015. As a result, the coverage of US GPS and BeiDou is almost equal. In addition, the accuracy is claimed to be between 3 and 5 metres, which is excellent and can even provide 10 cm of location precision, but it is only permitted for military uses. All I can say is that BeiDou is a reliable alternative to GPS and is equally as good as it.

The Best GPS Alternatives systems

One of these five GPS alternatives has been developed by Russia, India, China, the European Union, and Japan. As I indicated above, only a few countries have invested in creating satellite navigation systems, mainly for their security during aerial attacks, submarine wars, and ground battles. Remember that clients are not permitted to choose which GNSS system they can use. Everything depends on the hardware and navigation programmes people apply to mobile devices. So, remember that.
