With mobile apps, navigating foreign countries has become much easier
How navigation systems work and their types
Most apps that use geolocation work via GPS. The satellite determines the location of the device being used and sends a signal with coordinates to it. Then the app, using the received coordinates, shows the user the information they want to see.
There are several types of navigation systems, each described in detail on the resource https://agilie.com/en/services/geolocation-and-mapping-technologies. Here we briefly review four main types.
City guide. This system determines the user's location and informs them about various establishments nearby. Their main goal is to help a person navigate the city and not get lost. Therefore, the main advantage of such apps is the large amount of information about the city itself.
Maps and navigation. Such apps help a person find a route from point A to point B. Their main advantage is awareness of the traffic situation and calculation of when the user can reach the desired place. However, such apps often require not only GPS but also Wi-Fi so that the program can determine the traffic situation online.
Dating and geosocial services. Apps like Tinder and Badoo use geolocation for exactly this purpose. The program finds nearby users who are interested in dating, allowing you to make new friends online. A distinctive feature of such apps is that they show the distance to a potential friend instead of an exact address.
Location-based services. Many services allow you to order their services right to the user's door. And to avoid the hassle of entering an address, companies provide the ability to determine the user's location via Wi-Fi. This service is offered by taxis and delivery services.
What technologies are used
In addition to the well-known GPS, which works via satellite signals, other technologies are also involved in the operation of navigation apps.
For example, Cell ID allows determining the user's location using cell towers. This is relevant for cases when GPS cannot determine the location.
Wi-Fi can be used in a similar way. But the accuracy of location determination will depend on the number of routers nearby.
In case there is no internet, the location can be determined by a BLE chip. This works especially well when the user is indoors.
Geofencing is a popular technology that reacts to the user's location. For example, it informs about discounts if the user enters a store.
Despite today's achievements, navigation technologies continue to develop actively. Every year their accuracy and ease of use increase. This makes it only more interesting to watch their development path.
