Velocity or trajectory determination systems; Sense-of-movement determination systems

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Systems using the reflection or reradiation of acoustic waves, e.g. sonar systems > using reflection of acoustic waves > Systems of measurement based on relative movement of target > Velocity or trajectory determination systems; Sense-of-movement determination systems

CPC:

Systems using the reflection or reradiation of acoustic waves, e.g. sonar systems > using reflection of acoustic waves (G01S15/66 takes precedence) > Systems of measurement, based on relative movement of the target > Velocity or trajectory determination systems; Sense-of-movement determination systems

CPC subdivides this area 3x more granularly than IPC with 3 additional codes.

3 codes are CPC-only extensions.

IPC defines codes here since 1980.
