IDCITI is a South Korean deep-tech company specializing in precision positioning solutions for GNSS-denied environments. Headquartered in Songdo, Incheon, IDCITI develops technologies that extend reliable positioning to places where satellite signals cannot reach, such as tunnels, underground facilities, and dense industrial sites.

The company's flagship solutions include uGPS™, an SDR-based GNSS signal regeneration infrastructure that enables standard GNSS receivers to operate seamlessly inside tunnels and underground spaces without any device modification, and uTracker™, a solar-powered RTK wearable safety tracker that delivers sub-10 cm positioning accuracy for worker safety and asset intelligence at industrial worksites.

Backed by 13 patents, IDCITI is working with infrastructure operators and industrial partners to make positioning truly continuous — indoors, underground, and beyond.
