G01S RADIO DIRECTION-FINDING; RADIO NAVIGATION; DETERMINING DISTANCE OR VELOCITY BY USE OF RADIO WAVES; LOCATING OR PRESENCE-DETECTING BY USE OF THE REFLECTION OR RERADIATION OF RADIO WAVES; ANALOGOUS ARRANGEMENTS USING OTHER WAVES
Description
G01S covers systems and methods for determining position, direction, distance, and velocity using radio waves or analogous electromagnetic/acoustic signals. This includes radio navigation systems (GPS, LORAN, beacons), direction-finding equipment, radar and sonar technologies for object detection and ranging, and presence-sensing devices. The subclass encompasses both ground-based and satellite-based navigation, as well as Doppler and time-of-flight measurement techniques. Related optical positioning systems using light-based distance measurement are classified elsewhere in G01S's sister subclasses.
Filing statistics
CPC subclass G01S recorded 347,271 patent applications worldwide between 2013 and 2023. Annual filings grew from 14,634 in 2013 to 37,046 in 2023 (+153%), peaking at 43,431 applications in 2021. The most active applicants in class G01 are CHINESE ACADEMY OF SCIENCES (21,460 applications), ROBERT BOSCH (17,801 applications) and SGCC(STATE GRID CORPORATION OF CHINA) (17,347 applications).
