G01S 5/02 using radio waves (using satellite radio beacon systems for determining position G01S19/00)
Introduced: September 1968
Title
Titles differ between systems:
IPC: using radio waves
CPC: using radio waves (using satellite radio beacon systems for determining position G01S19/00)
Full Title
Full titles differ between systems:
Position-fixing by co-ordinating two or more direction or position-line determinations; Position-fixing by co-ordinating two or more distance determinations > using radio waves
Position-fixing by co-ordinating two or more direction or position line determinations; Position-fixing by co-ordinating two or more distance determinations > using radio waves (using satellite radio beacon systems for determining position G01S19/00)
CPC subdivides this area 3x more granularly than IPC with 12 additional codes.
12 codes are CPC-only extensions.
2 shared codes have differing titles between IPC and CPC.
