When we start finding any new place we always use google maps for it and its app name called google map ,it tells us all information from distance,time taken,traffic in route,have we ever thought how all this happen and works lets start-
Google Maps knows when there’s traffic
Every time you use Google Maps and allow it to access your location, the app will also send location data back to its servers. That way, when your location is on a roadway, Google is able to analyze in real-time whether you’re actually moving or if you’re stuck in traffic.
By pooling data from millions of users around the clock, Google is also able to see when and where you can expect heavy traffic.
A navigation system is a (usually electronic) system that aids in navigation. Navigation systems may be entirely on board a vehicle or vessel (on the ships) bridge, or they may be located elsewhere and communicate via radio or other signals with a vehicle or vessel, or they may use a combination of these methods.
- containing maps, which may be displayed in human readable format via text or in a graphical format.
- determining a vehicle or vessel’s location via sensors, maps, or information from external sources.
- providing suggested directions to a human in charge of a vehicle or vessel via text or speech.
Types of navigation systems–
- Automotive navigation system
- Marine navigation system
- satellite navigation system
- Surgical navigation system,
- Inertial guidance system
How Does Google Maps Work?
Google Maps has been a staple of the internet for over a decade now, but few actually know how it works. For the rest of us, Google Maps is pretty much one step away from magic.At a very basic level, Google Maps has taken a huge amount of offline information and published it online. We’re talking things like highway networks, road signs, street names, and business names.
When There’s a Mistake on Google Maps
Every day, masses of changes are made to Google Maps. Some of these may be the addition of new places and new roads while other changes may involve fixing mistakes.
Many of these are fixed by chance by members of the public: editing place descriptions, adding roads, and so on. Yet on top of this, Google has a large team of people working through the thousands of reports that are filed to Google each day.
Satellite Navigation – GPS – How It Works
Satellite Navigation is based on a global network of satellites that transmit radio signals in medium earth orbit. Users of Satellite Navigation are most familiar with the 32 Global Positioning System (GPS) satellites*. The United States, who developed and operates GPS, and Russia, who developed a similar system known as GLONASS, have offered free use of their respective systems to the international community.
The basic GPS service provides users with approximately 7.8 meter accuracy, 95% of the time, anywhere on or near the surface of the earth. To accomplish this, each of the 32 satellites emits signals to receivers that determine their location by computing the difference between the time that a signal is sent and the time it is received. GPS satellites carry atomic clocks that provide extremely accurate time.
