   Global Navigation Satellite System (GNSS) is a system of satellites that provide autonomous geo-spatial positioning with global coverage. It allows small electronic receivers to determine their location (longitude, latitude, and altitude) to within a few metres using time signals transmitted along a line-of-sight by radio from satellites. Receivers calculate the precise time as well as position, which can be used as a reference for scientific experiments. ReadMore..


   Is an proposed three-satellites regionl time treanfer system and satellite Based Augmentation Sytem for the Global Positioning System, specialy for Japan. The main target is to increase the visibilty of GPS signals in higly urban cities in japan and act as an augmentation system. The full installation will feature three satellites with highlty elliptical orbits. The fist quasi-zenith satellite "MICHIBIK"  was launched on 11th september 2010. ReadMore..


       Networked Transport of RTCM via Internet Protocol” (NTRIP stands for an application-level protocol streaming Global Navigation Satellite System (GNSS) data over the Internet. NTRIP is a generic, stateless protocol based on the Hypertext Transfer Protocol HTTP/1.1. The HTTP objects are enhanced to GNSS data streams. Readmore

GIC QZSS station

     base GIC is the home of one of the base monitoring stations for QZSS, GPS augmentation system developed by Japan. Established in Augest 2010.  The monitoring station is equiped with mini weather station that monitors weater information 24 hours. The base station provides real time information to the QZSS head quarters via high speed internet for monitoring and mantainense of the QZSS System.


NTRIP brodcasting station

     GIC operates a Trimble Reference Station system. The system includes a 12 channel Trimble Pro XR receiver capable of tracking 12 satellites simultaneously.This GPS base station is connected to the NTRIP Global Real-Time GPS Reference Stations Network on 2006 March 13th as First Base Station From Thailand. You can get access to the NTRIP Server by registoring.
