SEOUL, Sept. 6 (Korea Bizwire) — It is predicted that location information that is used in smartphones, drones and others will become more accurate in the future.
The National Geographic Information Institute (NGII) said Thursday that it will launch a satellite navigation-based positioning information service from the end of this year to expand its location-based service with State Space Representation, which was used for survey purposes, to general location-based services.
Location correction information is additional information that is used to improve accuracy on satellite measurements using GPS and other satellite navigation systems.
Since 2007, the NGII has provided free location correction information services via the Internet in real time.
The current method employed is the on atack replacement (OSR) method, which is used by more than 1 million people annually.
However, there is a limitation that requires the use of a measuring device, while a measurement is possible with an accuracy of 3 to 5cm.
In response, the NGII plans to implement a new method of State Space Representation to improve the accuracy of its positioning terminals, which are usually used in general location correction information services.
This service provides users with calibration information collected and generated by satellite base points across the country operated by the NGII after dividing correction information by errors.
It can also be applied to low-cost positioning devices that are used for smartphones or drones and is known to be more advantageous in positioning general location information users.
“We expect the service to expand opportunities to utilize high-precision location information and further boost the local location-based industry and service market,” said Sakong Ho-Sang, Director General of the NGII.
