G01S 19/00 - Definition
This main group covers:
Satellite radio beacon positioning systems including receivers and elements cooperating therewith.
Determination of position, velocity or attitude using signals transmitted by such systems.
Relationship between large subject matter areas
Satellite radio beacon positioning systems, of which GPS is the best known exponent, is a widely used technology.
This group and its subgroups, with the exception of the subgroups G01S 19/14-G01S 19/19 (see below), are the "function-places" for such technology.
Subgroups G01S 19/14-G01S 19/19 are "application-places for (GPS) receivers" insofar as they cover special characteristics of the (GPS) receivers, or specific constraints imposed on the receivers, so that they can adapt to the specific application. These subgroups do not cover the mere indication of the possible uses of a general GPS receiver.
The decision as to whether to classify in these groups will depend on the extent to which the invention relates to the core subject of these groups. Patent documents which deal with GPS merely as a "black box" to provide positioning information for use by the application, would not normally be classified in these groups.
Known applications of the technology are in the fields of surveying, navigation, network management, anti-theft and abduction and location based services – as listed in the section "Examples of places..." below.
