They must connect with a minimum of three satellites to utilize a process known as \u201c<a href=\"https:\/\/en.wikipedia.org\/wiki\/Trilateration\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">trilateration<\/a>\u201d. Once connected, it calculates the distance between the device and the satellites &#8211; thus pinpointing the location on Earth.\u00a0<\/p>\n\n\n\n<p>Some devices use assisted GPS. This means that they rely on additional data alongside satellite signals to determine exactly where you are. The extra data often comes from <a href=\"https:\/\/en.wikipedia.org\/wiki\/Wi-Fi_positioning_system\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Wi-Fi networks<\/a> and cell phone towers that broadcast signals to the GPS device. This information is then received and analyzed with satellite signals to triangulate your coordinates.\u00a0<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"how-do-gps-systems-worknbsp\"><strong>How Do GPS Systems Work? <\/strong><\/h2>\n\n\n<p>The GPS (Global Positioning System) comprises a worldwide network of 31 satellites that transmit radio signals back to Earth. The GPS satellite network was originally developed and operated by the United States.\u00a0<\/p>\n\n\n\n<p>However, there are also other satellite constellations in space that have a similar purpose. These are collectively known as the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Satellite_navigation\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Global Navigation Satellite System<\/a> or GNSS and consist of systems from Russia, China, and the European Union.\u00a0<\/p>\n\n\n\n<p>The satellite signals are sent to Earth and picked up by GPS receivers which collate the data to work out a particular location based on the distance and time that passed since the release of the signal.<\/p>\n\n\n\n<p>The device must receive four separate satellites to accurately determine your location.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"how-does-a-gps-receiver-worknbsp\"><strong>How Does a GPS Receiver Work? <\/strong><\/h2>\n\n\n<p><a href=\"https:\/\/en.wikipedia.org\/wiki\/Satellite_navigation_device\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">GPS receivers<\/a> are designed to receive information from satellite signals that pinpoint where that particular satellite is at a certain moment in time. It then uses this data to calculate the device&#8217;s location on the planet.\u00a0<\/p>\n\n\n\n<p>The radio waves emitted by the satellites travel at a continuous speed. Therefore, GPS receivers measure the amount of time it has taken for each satellite signal to arrive at the device and then calculate the distance and as a result, the location based on this data.\u00a0<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"how-do-gps-jammers-worknbsp\"><strong>How Do GPS Jammers Work? <\/strong><\/h2>\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/2-55.jpg\" alt=\"\" class=\"wp-image-2798\" srcset=\"https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/2-55.jpg 1000w, https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/2-55-300x200.jpg 300w, https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/2-55-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>Wrong way sign<\/em><\/p>\n\n\n\n<p>GPS jammers are compact and self-contained devices that hide your location. They do this by emitting radio signals at the same frequency as a GPS device. When this happens, the interference overwhelms the GPS receiver, so it is unable to calculate its position.\u00a0<\/p>\n\n\n\n<p>However, it\u2019s important to note that GPS jammers are illegal in many countries due to the disruption they can cause to navigation and aviation.\u00a0<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"how-does-gps-navigation-worknbsp\"><strong>How Does GPS Navigation Work? <\/strong><\/h2>\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/Depositphotos_2307123_S.jpg\" alt=\"A GPS handheld device placed onto a paper map\" class=\"wp-image-2801\" srcset=\"https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/Depositphotos_2307123_S.jpg 1000w, https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/Depositphotos_2307123_S-300x200.jpg 300w, https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/Depositphotos_2307123_S-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>A GPS handheld device placed onto a paper map<\/em><\/p>\n\n\n\n<p>As a GPS device uses location information from at least 4 satellites.

You can use them for location tracking, <a href=\"https:\/\/starlinkhow.com\/asset-tracking-gps\/\" target=\"_blank\" rel=\"noreferrer noopener\">asse<\/a>t tracking, transportation, mapping and surveying, navigation, law enforcement, aviation, time zone monitoring, hiking, fishing, and for health and fitness products.\u00a0<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"are-gps-devices-accuratenbsp\">Are GPS Devices Accurate? <\/h3>\n\n\n<p>GPS devices are incredibly accurate. Due to the way they work, they can continue to provide positioning information even in cramped environments such as heavy tree cover or tall buildings. In some cases, atmospheric issues or conflicting signals may affect accuracy, but most GPS devices will provide a precise location within a 10-meter radius.&nbsp;<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"can-i-use-gps-without-cell-phone-datanbsp\">Can I Use GPS Without Cell Phone Data? <\/h3>\n\n\n<p>Yes, it is possible to use GPS without a cell phone data connection. If you are using the GPS capability <a href=\"https:\/\/starlinkhow.com\/how-does-iphone-gps-work\/\" target=\"_blank\" rel=\"noreferrer noopener\">on your cell phone<\/a>, location information is received from satellites.\u00a0<\/p>\n\n\n\n<p>Therefore, so long as you have an offline map, you can use GPS to find your location and navigate. However, you will not get any live updates regarding traffic flow or road closures.\u00a0<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"conclusion\"><strong>Conclusion:<\/strong><\/h2>\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"685\" src=\"https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/4-48.jpg\" alt=\"Satellite in space\" class=\"wp-image-2792\" srcset=\"https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/4-48.jpg 1000w, https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/4-48-300x206.jpg 300w, https:\/\/starlinkhow.com\/wp-content\/uploads\/2023\/01\/4-48-768x526.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>Satellite in space<\/em><\/p>\n\n\n\n<p>GPS (Global Positioning System) devices use signals from a global network of orbiting satellites to determine your location accurately.
