Radio Propagation Monitoring Technology  
There are many sorts of error, such as orbit ephemeris error, satellite clock error, Ionosphere delay error,
troposphere delay error, multi-path error, RFI(Radio Frequency Interference), jamming and so on, in GNSS
which is used in various applications on the earth.
Consequently, in order to effectively response to not only radio disturbances of GNSS, but also intended and non-intended signal jamming caused by a rapid increase of the LBS(Location Based Service) applications.
GNSS signal monitoring technology and jamming signal monitoring technology are obviously necessary.
 
[Our technologies]  
   • Analysis and monitoring technology for the satellite failure, satellite's orbit ephemeris error and clock
     error
   • Analysis and correction technology for the errors caused by ionosphere, troposphere disturbances
   • Multipath delay analysis technology  
   • Analysis and reduction technology for RFI caused by solar flare and natural electromagnetic interferences
   • Analysis and tracking technology for the Intended and non-Intended Jamming, SA (Selective Availability) and son on.
