Google Maps is a web mapping platform and consumer application offered by Google. It offers satellite imagery, aerial photography, street maps, 360° interactive panoramic views of streets, real-time traffic conditions, and route planning for traveling by foot, car, bike, air and public transportation. As of 2020, Google Maps was being used by over one billion people every month around the world.
OpenStreetMap is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and as a result commonly used to make electronic maps, inform turn-by-turn navigation, assist in humanitarian aid and data visualisation. OpenStreetMap uses its own topology to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an online map, geodata search engine and editor.
Since the Global Positioning System (GPS) was introduced in the late 1980s there have been many attempts to integrate it into a navigation-assistance system for blind and visually impaired people.

Satellite navigation software or GNSS navigation software usually falls into one of the following two categories:
- Navigation with route calculation and directions from the software to the user of the route to take, based on a vector-based map, normally for motorized vehicles with some motorized forms added on as an afterthought.
- Navigation tracking, often with a map "picture" in the background, but showing where you have been, and allowing "routes" to be preprogrammed, giving a line you can follow on the screen. This type can also be used for geocaching.
A satellite navigation device, satnav device or satellite navigation receiver is a user equipment that uses one or more of several global navigation satellite systems (GNSS) to calculate the device's geographical position and provide navigational advice. Depending on the software used, the satnav device may display the position on a map, as geographic coordinates, or may offer routing directions.
Here Technologies is a Dutch multinational group specialized in mapping technologies, location data, and related automotive services to individuals and companies. It is majority-owned by a consortium of German automotive companies and American semiconductor company Intel whilst other companies also own minority stakes. Its roots date back to U.S.-based Navteq in 1985, which was acquired by Finland-based Nokia in 2007. Here is currently based in The Netherlands.
Google Maps Navigation is a mobile application developed by Google for the Android and iOS operating systems that later integrated into the Google Maps mobile app. The application uses an Internet connection to a GPS navigation system to provide turn-by-turn voice-guided instructions on how to arrive at a given destination. The application requires a connection to Internet data and normally uses a GPS satellite connection to determine its location. A user can enter a destination into the application, which will plot a path to it. The app displays the user's progress along the route and issues instructions for each turn.
OpenSeaMap is a software project collecting freely usable nautical information and geospatial data to create a worldwide nautical chart. This chart is available on the OpenSeaMap website, and can also be downloaded for use as an electronic chart for offline applications.
Waze Mobile Ltd, doing business as Waze, formerly FreeMap Israel, is a subsidiary company of Google that provides satellite navigation software on smartphones and other computers that support the Global Positioning System (GPS). In addition to turn-by-turn navigation, it incorporates user-submitted travel times and route details while downloading location-dependent information over a cellular network. Waze describes its application as a community-driven initiative that is free to download and use.
Sygic is a Slovak company of global automotive navigation systems for mobile phones and tablets. The company was founded in 2004 and is headquartered in Bratislava, Slovakia. It became the first company to offer navigation for iPhone and second for Android. In 2015 Sygic reached milestone of 100 million downloads of its navigation app.
Turn-by-turn navigation is a feature of some satellite navigation devices where directions for a selected route are continually presented to the user in the form of spoken or visual instructions. The system keeps the user up-to-date about the best route to the destination, and is often updated according to changing factors such as traffic and road conditions. Turn-by-turn systems typically use an electronic voice to inform the user whether to turn left or right, the street name, and the distance to the next turn.
Retroshare is a free and open-source peer-to-peer communication and file sharing app based on a friend-to-friend network built by GNU Privacy Guard (GPG). Optionally peers may exchange certificates and IP addresses to their friends and vice versa.
OsmAnd is a map and navigation app for Android and iOS. It uses the OpenStreetMap (OSM) map database for its primary displays, but is an independent app not endorsed by the OpenStreetMap Foundation. It is available in both free and paid versions; the latter unlocks the download limit for offline maps and provides access to Wikipedia points of interest (POIs) and their descriptions from within the app. Map data can be stored on the device for offline use. Using the device's GPS capabilities, OsmAnd offers routing, with visual and voice guidance, for car, bike, and pedestrian. All of the main functionalities work both online and offline.
This article contains a list with gratis satellite navigation software for a range of devices. Some of the free software mentioned here does not have detailed maps or the ability to follow streets or type in street names. However, in many cases, it is also that which makes the program free, avoid the need of an Internet connection, and make it very lightweight. Very basic programs like this may not be suitable for road navigation in cars, but serve their purpose for navigation while walking or trekking, and for use at sea. To determine the GPS coordinates of a destination, one can use sites such as GPScoordinates.eu and GPS visualizer.
Maps.me is a mobile app for Android, iOS and BlackBerry that provides offline maps using OpenStreetMap data. It was formerly known as MapsWithMe. In November 2014, it was acquired by Mail.Ru Group and became part of its My.com brand. In September 2015, the app was open sourced and a free and open-source software version was additionally made available on F-droid until the application was sold to the payment processor Daegu Limited, part of Parity.com, which changed the application user interface and content, leading original MapsWithMe founders Alexander Borsuk and Viktor Govako to release an open source ad- and tracker-free fork called 'Organic Maps' in response.
Here WeGo is a web mapping and satellite navigation software, operated by HERE Technologies and available on the Web and mobile platforms.
