GPS<\/a> GLONASS Galileo and BeiDou are some of the most well-known navigation systems. <\/p>\n\n\n\n Once upon a time, GPS was the only seemingly available satellite navigation system for consumers. In fact, GPS is essentially synonymous with satellite navigation. <\/p>\n\n\n\n We call wearables and navigation systems GPS watches and GPS trackers (respectively), even though they support and cater to different navigation systems. <\/p>\n\n\n\n Ultimately, you may be using (what we refer to) a GPS watch that uses a different Satellite system (such as GNSS) by default. <\/p>\n\n\n\n But what\u2019s the difference between each system, and which one is the best for you? The following guide will answer these questions and more. <\/p>\n\n\n\n Many GPS-enabled devices allow you to choose alternative satellite navigation (satnav)\/tracking systems that aren\u2019t GPS. You can even select different combinations.<\/p>\n\n\n\n Global civilian satnav systems like GPS fall under the umbrella of Global Navigation Satellite Systems<\/a> (GNSS). Not all GNSSs are equal. There are currently two classifications:<\/p>\n\n\n\n Most GNSSs are gen 1 (GNSS-1) – mostly because they use a single frequency band. However, more manufacturers have begun to roll out dual-band devices. <\/p>\n\n\n\n All GNSSs have three main functions: positioning, navigation and timing.<\/p>\n\n\n\n Some work better than others, mainly because of their coverage and augmentation systems. Ultimately, each GNSS consists of a constellation – much like Starlink<\/a>. <\/p>\n\n\n\n So let\u2019s look at what separates GPS, GLONASS, Galileo and BeiDou. Let\u2019s look at them all individually first.<\/p>\n\n\n\n GPS watch<\/p>\n\n\n\n The Global Positioning System (GPS) is a North American GNSS developed and run by the United States government. Many consider it to be the first global Satnav system.<\/p>\n\n\n\n When the US government first instituted GPS in 1979, it intended it exclusively for military purposes. <\/p>\n\n\n\n The US Navy would use it as a navigation system. It wasn\u2019t until 1983 that the US government finally allowed it for civilian use.<\/p>\n\n\n\n As of December 2023, the GPS constellation consists of roughly 31 operational satellites (35 in total). <\/p>\n\n\n\n With satellites regularly losing operability and NASA and the US Space Force developing and launching new ones, this number tends to fluctuate.<\/p>\n\n\n\n Nevertheless, the GPS constellation is so well-distributed that people should be able to spot at least four of its satellites regardless of their location. <\/p>\n\n\n\n This makes GPS available in almost every country. <\/p>\n\n\n\n The more satellites in range, the more accurate triangulation and navigation will be.<\/p>\n\n\n\n On average, GPS-capable devices are accurate within a 4.9 meters radius under clear open, unobstructed skies. Incidentally, accuracy is also dependent on not only your location but the device you use.<\/p>\n\n\n\n For instance, GPS coordinates you capture through professional GPS land surveying<\/a> equipment will likely be more accurate than those of wearables.<\/p>\n\n\n\n Glonass Global Positioning System Red Arrows<\/p>\n\n\n\n In an effort to stay competitive with the United States of America, Russia released its own global satellite navigation system. <\/p>\n\n\n\n They dubbed it Global’naya Navigatsionnaya Sputnikovaya Sistema\\Global Navigation Satellite System (GLONASS). The Russian government (Soviet Union) began development in 1976. <\/p>\n\n\n\n As of December 2023, they\u2019ve launched roughly over 145 satellites since then. Roughly 133 of these satellites were successful. <\/p>\n\n\n\n There are currently 24 operational satellites in the GLONASS constellation. <\/p>\n\n\n\n Some sources estimate that there may be an additional 7 dysfunctional satellites, meaning there are a total of 31 satellites in the constellation.<\/p>\n\n\n\n There have been different versions of GLONASS since its inception. Additionally, the Russian government plans to release new, improved implementations. <\/p>\n\n\n\n All known current versions include:<\/p>\n\n\n\n If you have a modern GNSS device that can access GLONASS, you may have noticed an additional version that your device has labeled \u201cA-GLONASS.\u201d<\/p>\n\n\n\n This isn\u2019t an entirely different version of GLONASS.<\/p>\n\n\n\n Instead, it\u2019s an augmented version that can perform more accurate triangulations thanks to augmentation systems and cell phone infrastructure. <\/p>\n\n\n\n Consequently, A-GLONASS is more accurate and makes features such as turn-by-turn navigation possible.<\/p>\n\n\n\n Technology Communication Image Global Navigation Satellite<\/p>\n\n\n\n Galileo is one of the most recent civilian-grade GNSS solutions. Where GPS is a product of the USA and GLONASS of Russia, the European Union (EU) is responsible for the creation and management of Galileo.<\/p>\n\n\n\nUnderstanding Global Navigation Systems<\/h2>\n\n\n\n
