An engineering lab at University of Texas in Austin designed a low-cost portable global positioning system with precision to a few centimeters, and started a company to take the technology to market. A team from UT-Austin&#8217;s <a href=\"http:\/\/radionavlab.ae.utexas.edu\/\">Radionavigation Laboratory<\/a>, led by engineering professor <a href=\"https:\/\/www.ae.utexas.edu\/faculty\/faculty-directory\/humphreys\">Todd Humphreys<\/a>, designed the technology, which they believe can be used in virtual reality, drone navigation, mapping, agriculture, and collision-avoidance systems in cars.<\/p>\n<p>The team points out that current GPS devices in cars and smartphones are accurate to 2-3 meters. Higher performance and more accurate GPS systems &#8212; to millimeter accuracy &#8212; are also available for surveying and agriculture, but those systems designed for commercial applications are large and expensive.<\/p>\n<p>Humphreys and colleagues outlined their discoveries in February in the trade publication <em><a href=\"http:\/\/radionavlab.ae.utexas.edu\/images\/stories\/files\/papers\/accuracy-in-the-palm-of-your-hand.pdf\">GPS World<\/a><\/em>, and at a meeting in September 2014 of the <a href=\"http:\/\/radionavlab.ae.utexas.edu\/images\/stories\/files\/papers\/ion2014Pesyna.pdf\">Institute of Navigation<\/a>. The researchers are focusing on improving the <a href=\"http:\/\/radionavlab.ae.utexas.edu\/research\/381-precise-mass-market-mobility\">reception of signals<\/a> from global navigation satellites, which in current consumer devices depends on antennas that they describe as &#8220;little better than smashed paperclips.&#8221;<\/p>\n<figure style=\"width: 202px\" class=\"wp-caption alignleft\"><a href=\"http:\/\/radionavlab.ae.utexas.edu\/people\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/radionavlab.ae.utexas.edu\/images\/stories\/Photos\/people\/todd.jpg\" alt=\"Todd Humphreys\" width=\"202\" height=\"217\" \/><\/a><figcaption class=\"wp-caption-text\">Todd Humphreys (University of Texas, Austin)<\/figcaption><\/figure>\n<p>Their solution is a new type of receiver software that extracts and analyzes the satellite signals for <a href=\"http:\/\/www.insidegnss.com\/node\/2146\">carrier phase measurements<\/a>, the range between a satellite and receiver expressed in units of cycles of the carrier frequency. The software currently runs on a device added on to a smartphone that uses the existing antenna and doesn&#8217;t interfere with the phone&#8217;s built-in circuitry. The team tested the add-on device against reference measurements made by commercial-grade GPS systems, showing a smartphone with the add-on device is able to calculate locations within a few centimeters, about the size of a nickel.<\/p>\n<p>Humphreys and three graduate students working on the project founded <a href=\"http:\/\/www.radiosense.com\/\">Radiosense LLC<\/a> that licensed the geopositioning technology from the university. While commercial applications of the technology for the company are already known, still missing is more of a mass-market application, the so-called killer app.<\/p>\n<p>That more widespread application may be virtual or augmented reality, where greater positioning precision can get gamers off the couch and out in the open air to engage their opponents. &#8220;Imagine games where, rather than sit in front of a monitor and play, you are in your backyard actually running around with other players,&#8221; says Humphreys in a <a href=\"http:\/\/news.utexas.edu\/2015\/05\/05\/texas-engineers-develop-centimeter-accurate-gps-system\">university statement<\/a>. &#8220;To be able to do this type of outdoor, multiplayer virtual reality game, you need highly accurate position and orientation that is tied to a global reference frame.&#8221; The video at top demonstrates its use in a virtual reality headset.<\/p>\n<p>The developers say Radiosense is working with smartphone maker Samsung to create an attachment for virtual reality applications, which is providing funding for the Radionavigation Lab&#8217;s research. But they also believe the device can be used in vehicle-to-vehicle communication systems to prevent collisions. &#8220;If your car knows in real time the precise position and velocity of an approaching car that is blocked from view by other traffic,&#8221; notes Humphreys,\u00a0 &#8220;your car can plan ahead to avoid a collision.&#8221;<\/p>\n<p>Read more:<\/p>\n<ul>\n<li><a href=\"http:\/\/sciencebusiness.technewslit.com\/?p=26351\">Activity Trackers Adapted for Clinical Trial Data<\/a><\/li>\n<li><a href=\"http:\/\/sciencebusiness.technewslit.com\/?p=26137\">Behavioral App Developer Lands $20 Million in Venture Funds<\/a><\/li>\n<li><a href=\"http:\/\/sciencebusiness.technewslit.com\/?p=17519\">Simple, Low-Cost Method Adds Microscope Lens to Smartphone<\/a><\/li>\n<li><a href=\"http:\/\/sciencebusiness.technewslit.com\/?p=15915\">Algorithm Designed for Cars to Alleviate Traffic Jams<\/a><\/li>\n<li><a href=\"http:\/\/sciencebusiness.technewslit.com\/?p=14752\">Research to Develop Peer-to-Peer VoIP Security Protocol<\/a><\/li>\n<\/ul>\n<p style=\"text-align: center;\">*\u00a0\u00a0\u00a0\u00a0 *\u00a0\u00a0\u00a0\u00a0 *<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Video: Centimeter-level GPS used in a virtual reality headset (University of Texas, Austin) 6 May 2015.
