A garment prepared from a smart fabric, wherein the smart fabric comprises:
- one or more devices providing satellite positioning measurement, accelerometer measurement, or both, conductively coupled to a battery or other DC power source;
- and a conductive composite yarn conductively coupled to the one or more devices providing satellite positioning measurement, accelerometer measurement, or both, wherein the conductive composite yarn comprises:
- a) a core formed of at least two strands of a conductive metal of 40 or higher gauge, wherein the at least two strands of conductive metal are configured such that one strand is wrapped around the other strand at a wrap rate of from 1 to 50 turns per inch (tpi);
- and
- b) at least one inner cover wrapped around the core in a first direction at a rate sufficient to provide substantially complete coverage of the core by the inner cover;
- c) at least one outer cover wrapped around the at least one inner cover, wherein the outer cover is wrapped in a second direction opposite to a direction of a cover layer on which the outer cover is directly wrapped, at a rate sufficient to provide substantially complete cover of the cover layer on which the outer cover is directly wrapped;
- and
- d) at least one bonding agent.
