Not the right word, since the GPS radios in smartphones do not transmit to the GPS satellites. “Receive” … YES. These GPS receivers (whether in cell phones or personal navigation devices) tune the receivers to the correct frequencies that are being used by the GPS satellites.
Do iphones have a GPS receiver?
Positioning. The iPhone includes a regular GPS receiver, just like your standalone GPS. The “assisted” part means the iPhone is able to get a quick lock based on other data sources, such as nearby cell phone towers or WiFi networks.
The Maps app requires an internet connection to download the Map information and imagery as you move along. The GPS itself does not require an internet connection. You need a Maps App that can download the maps before hand, so they can be used without an internet connection.
The Befefon Esc! was the first mobile phone with GPS built in. 1999 Mobile phone manufacturer Benefon launched the first commercially-available GPS phone, a safety phone called the Benefon Esc! The GSM phone was sold mainly in Europe, but many other GPS-enabled mobile phones would follow.
If the GPS satellites aren't visible to the receiver, then they can still get a rough fix from the cellular towers. Yes, Google maps and all other cell phone mapping systems require a data connection of some sort at varying times during usage.
How does GPS work? The Global Positioning System (GPS) is a network of about 30 satellites orbiting the Earth at an altitude of 20,000 km. Once it has information on how far away at least three satellites are, your GPS receiver can pinpoint your location using a process called trilateration.
First, some iOS devices have a GPS chip and some do not. All iPhone models (4, 4S, 5, 5C, 5S, 6, 6+) include a GPS chip. No iPod-Touch model has a GPS chip. All iPad models that have 3G or Cellular also have GPS chip and therefore behave like an iPhone for mapping purposes.

The truth is they are not. Your cell phone carrier might have an extensive network that allows you to make calls to and from al-most any location, access the Internet or run applications, but cell phones transmit signals very differently than satellite phones. Cellular phones transmit via land-based towers.
GPS systems are extremely versatile and can be found in almost any industry sector. They can be used to map forests, help farmers harvest their fields, and navigate airplanes on the ground or in the air. GPS systems are used in military applications and by emergency crews to locate people in need of assistance.
Mobile phone tracking. Mobile phone tracking is the ascertaining of the position or location of a mobile phone, whether stationary or moving. Localization may occur either via multilateration of radio signals between (several) cell towers of the network and the phone, or simply via GPS.
The iPhone uses the GPS chip in conjunction with cell phone towers and Wi-Fi networks—in a process termed "assisted GPS"—to quickly calculate the phone's position. You don't need to set up the GPS chip, but you can turn it off or enable it selectively on the iPhone.
GPS tracking is the surveillance of location through use of the Global Positioning System (GPS ) to track the location of an entity or object remotely. The technology can pinpoint longitude, latitude, ground speed, and course direction of the target.
GPS works by providing information on exact location. A GPS tracking system uses the Global Navigation Satellite System (GNSS) network. This network incorporates a range of satellites that use microwave signals that are transmitted to GPS devices to give information on location, vehicle speed, time and direction.
And most recently, it's what allows you to tag your digital photos with precise geographic information. GPS photo tagging, also known as geotagging, is the process of embedding a digital photo with latitude, longitude and even altitude data.
In the most basic form, a cell phone is essentially a two-way radio, consisting of a radio transmitter and a radio receiver. When you chat with your friend on your cell phone, your phone converts your voice into an electrical signal, which is then transmitted via radio waves to the nearest cell tower.
Assisted GPS (abbreviated generally as A-GPS and less commonly as aGPS) is a system that often significantly improves the startup performance—i.e., time-to-first-fix (TTFF)—of a GPS satellite-based positioning system.
Uses of Satellites. Satellites are launched into space to do a specific job. The type of satellite that is launched to monitor cloud patterns for a weather station will be different than a satellite launched to send television signals for Sky TV. The satellite has to be designed specifically to fulfill its function.
Satellites are used for many purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and space telescopes. Space stations and human spacecraft in orbit are also satellites.
Satellites orbit Earth at different heights, different speeds and along different paths. The two most common types of orbit are "geostationary" (jee-oh-STAY-shun-air-ee) and "polar." A geostationary satellite travels from west to east over the equator.
About 1,100 active satellites, both government and private. Plus there are about 2,600 ones that no longer work. Russia launched the first satellite, Sputnik 1, in 1957. The oldest one still in orbit, which is no longer functioning, was launched in 1958.
