No personal user data is collected without the explicit user consent. You can withdraw your given consent at any moment if you wish to do so. HERE welcomes the users to share certain data in order to provide a better service, and offers users to consent to it. Even when consent is given, all collected data used in services is fully anonymized and can't be tracked back to individuals. Users can request the removal of all collected personal data in the app.

Some features may require the use of a HERE account, such as when you want to synchronize your Collections. You can also continue using other features of the service without signing in. When you sign up for a HERE account, we collect your name, email address, date of birth and country of residence. Once you are logged in with your HERE account, we automatically try to synchronize your recent searches and the collections associated with your HERE account.

The service makes use of information about your actual location ("location data") and places ("place information"). Location data reveals where you currently are or where you have been. Location Data is based on available positioning methods, such as Assisted GPS. In many device models, the user interface of the Service identifies the use of positioning with an icon. Place information is general information pertaining to particular geographical locations (ie, a city of the location of a restaurant) which you provided to us in your Collections, for example. Unless otherwise stated, we use random identifiers in connection with your location data that do not identify you personally. When you start to use the service, the applicable service activates your selected positioning methods to retrieve your current location. The service may send your location data to HERE when you use location-enabled features of the service online, such as asking for information about nearby services or offerings, using search features, as well as when the service asks for new maps for new areas you previously navigated to. The location data may be collected when you use the traffic feature for service improvement purposes without identifying you personally. Place information may be sent to HERE, for example, when you synchronize your collections.

Turning on 'Traffic' allows the app to send HERE information about your ride (ie, your car's location, the directions of travel, etc). We combine this info with what other drivers have sent to provide you with better and faster routes.

Rest Areas are public facilities available on highways or motorways where drivers can take a break. You can usually find gas stations, restrooms and/or places to buy food in these areas.If you open the WeGo app, drag up the bottom bar and select 'Settings', you'll find a toggle switch for the 'Rest Areas' functionality. Once turned on, the app will start showing the rest areas available on your way (if any), especially when you're driving on highways.When the app shows the rest area icon, you can click on it and add it as a stop on your route.

We work hard to keep the maps as current as possible but as data constantly changes around the world, some of these changes can take a while before they show p in our maps. Please, use the 'Suggest an edit' option when you'd like to report issues about outdated POI information in our maps. If you'd like to report any other issue, please send an email to appsu...@here.com with more details or use the Map Creator tool.

In 1957, Russia launched Sputnik, the first satellite to successfully orbit the Earth. As Sputnik orbited the planet, the satellite emitted a radio signal. A group of scientists in the Applied Physics Laboratory (APL) at Johns Hopkins University observed a strange phenomenon: The frequency of radio signals transmitted by Sputnik increased as the satellite approached, and the signal frequency decreased as it moved away.

In November 1972, Air Force Col. Bradford Parkinson was tasked with overseeing the satellite navigation program. Parkinson led a team in developing a concept that synthesized the best aspects of TRANSIT, Timation, and Project 621-B. This revised system proposal received Defense Department approval in December 1973 for a passive 1-way ranging system of 24 satellites, which used atomic clocks at medium Earth orbits to provide a 12-hour period.

The primary incarnation of this approach began in 1974 when the U.S. Air Force started development of the first of a series of Navstar satellites, the ground control system, and various types of military user equipment.

In February 1978, the first Block I developmental Navstar/GPS satellite launched, with three more Navstar satellites launched by the end of 1978. More than 700 tests were conducted between 1977 and 1979, in which Aerospace engineers helped confirm the accuracy of the integrated space/control/user system. Additional GPS Block I demonstration satellites were launched in the early 1980s.

GPS technology continued to improve through the 1980s and 1990s. The production and development phase began in 1985 and the first operational GPS Block II satellite was launched on a Delta II rocket in 1989.

As GPS coverage continued to expand to full operational capabilities, so did its reach into the lives of civilians. GPS technology appeared for the first time in a cellphone in 1999 when Benefon released Benefon Esc!, a GPS-equipped phone that would lead the way for more. GPS technology also began to show up in automobiles.

The price of GPS receiver and processing chips also dropped from roughly $3000 to $1.50. The increase in accuracy coupled with the decrease in cost led to exponential growth in GPS usage for in-car navigation, location-based services, personal technology and usage in shipping, sailing and other industries.

By 2000, it was recognized that the system needed to be modernized to meet rapidly expanding military and civilian applications. A strategy to add new signals to satellites not yet launched was developed, while meeting the full modernized requirements would take a new program, designated GPS III.

At the same time, the GPS III program began its DoD approval path, leading to satellite contract award in 2008, and ground system contract award in 2010. The first GPS III satellite was launched on a SpaceX Falcon 9 in 2018, followed by the second satellite launched on a ULA Delta IV in 2019 and the third and fourth GPS III satellites launched on Falcon 9 rockets in 2020. The remaining six satellites are scheduled to be launched by 2023.

The Global Positioning System (GPS), originally Navstar GPS,[2] is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force.[3] It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.[4] It does not require the user to transmit any data, and operates independently of any telephone or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver.[5]

After Korean Air Lines Flight 007 was shot down when it mistakenly entered Soviet airspace, President Ronald Reagan announced that the GPS system would be made available for civilian use as of September 16, 1983;[6] however, initially this civilian use was limited to an average accuracy of 100 meters (330 ft) by use of Selective Availability (SA), a deliberate error introduced into the GPS data (which military receivers could correct for).

As civilian GPS usage grew, there was increasing pressure to remove this error. The SA system was temporarily disabled during the Gulf War, as a shortage of military GPS units meant that many US soldiers were using civilian GPS units sent from home. In the 1990s, Differential GPS systems from the US Coast Guard, Federal Aviation Administration, and similar agencies in other countries began to broadcast local GPS corrections, reducing the effect of both SA degradation and atmospheric effects (that military receivers also corrected for). The US military had also developed methods to perform local GPS jamming, meaning that the ability to globally degrade the system was no longer necessary. As a result, President Bill Clinton signed a bill ordering that Selective Availability be disabled on May 1 2000;[7] and, in 2007, the US government announced that the next generation of GPS satellites would not include the feature at all.
