Enhanced positioning accuracy by the KASS expected in the position-based industry, etc.
The Ministry of Land, Infrastructure and Transport (MOLIT, Minister WON Hee-ryong) announced that the Korea Augmentation Satellite System(KASS) will provide the significantly precise positioning information service to all over the country for the first time on 15 December by reducing GPS’s positioning error up to the level of 1~1.6 m.
* KASS(Korea Augmentation Satellite System): Korean style differential global positioning system that provides precise position in real-time by reducing the GPS’s positioning error (15~33 m → 1.6 m), which was registered as 7th international standard
After the successful launch of the Augmentation Satellite No. 1 (23 June), the processes such as linking test and performance verification, etc. by each step between ground systems* have been made. It is going to provide the KASS signal in advance to test and utilize it over diverse fields such as position-based industry, academic research, and so forth, prior to starting aviation service at the end of 2023.
* Domestically, there are 7 reference stations, 2 uplink stations, and 2 central processing & integrated operation stations all over the country.
Prior to the first provision of the KASS precision positioning signal, it carried out performing tests for its accuracy improvement by using vehicles, etc. with the researcher from the Korea Aerospace Research Institute, which is the research institute in charge, confirming that the current GPS error has been reduced to the level of 1 m.
