Soon the people in South Korea have more accurate GPS navigation systems in their car or vehicles. South Korea has developed a technology to allow the use of an advanced global positioning system (GPS) in any ordinary digital multimedia broadcasting device, such as car navigation systems, the government said Tuesday.
Advanced global positioning system (GPS) also known as Differential Global Positioning System (DGPS) has an accuracy of less than 1 meter (0.97536 m or 3.2 feet) where as conventional GPS is accurate up to 36.8808 meters or 121 feet.
As reported by the Yonhap News Agency, the new technology, also known as differential GPS (DGPS), could reach the public as early as next year.
DGPS typically demands an expensive device on the receiving end and is currently used by fishing vessels and around 790 different organizations, Yonhap said. But the new technology lets an ordinary navigation device take advantage of DPGS by simply replacing its GPS chip with a multipurpose chip, according to South Korea’s Ministry of Oceans and Fisheries.
The more advanced GPS promises greater reliability in terms of position accuracy. “The start of the DGPS service for the public will significantly improve the accuracy of conventional location services that use the global navigation satellite system, such as personal navigation systems, which will also become a new growth engine for the related industry,” Lim Hyeon-cheol, a ministry official, told reporters, Yonhap added.
South Korea is also developing what it calls a satellite-based augmentation system (SBAS), which literally is an augmentation to the global navigation system that will cut the navigation system’s margin of error to 1 meter while also enhancing the system’s reliability and availability.
The ongoing program seeks to develop the SBAS by 2018 for the start of its commercial use in 2020.
