South Korea aims more accurate GPS at navigation systems

The advanced GPS, also called differential GPS, has a margin of error of just 3.2 feet. That's a big improvement over conventional GPS which is accurate up to 121 feet.

Drivers may one day be able to tap into more accurate and reliable GPS, courtesy of a new development in South Korea.

Technology created in the country can enable advanced GPS in ordinary devices, such as a car's navigation system, the South Korean government announced on Tuesday. 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. Conventional GPS is accurate up to 121 feet, but DGPS cuts that number down to just 3.2 feet.

"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.
