Our company was established as a specialized for satellite positioning technology in Aug. 2002．Our members have a long experience to lead the most of major social infrastructure in Japan. We are now focusing to create 3-D seamless positioning environment in world-wide by normal GPS/GNSS receiver that is installed in a smartphone. The next coming technology is 「3D-SEAMLESS INDOOR NAVIGATION WITH SMARTPHONE」. In 2012, we completedto develop miniture IMES TX based on our developing LSI. IMES (=Indoor messaging system or Indoor measuring system) is now patented globally with several relative patents. This is an epoch making technology that is cheap to install into smartphone with no change hardware, ultra low power consumption for GNSS receiver and very stable accuracy in indoor positioning. IMES can perform A PERFECT THREE DIMENTIONAL INDOOR NAVIGATION BY NORMAL GNSS RECEIVERS. Its' PRN codes were certified by US Government. We also provide total solution products for commercial use such as「SET UP SOFTWARE」, 「DATABASE MANAGEMENT SOFTWARE」 and 「COORDINATE GENERATOR with PROPAGATION SIMULATION　FUNCTION」 for installation works of miniture IMES TX by company. We are also preparing IMES Simulation System for development IMES function by engineer.
