16. IS-GNSS Oct. 2014 - Slide 15 Performance Improvement Provide Vertical Guidance – –APV-I (LPV) or hopefully CAT-I (LPV200) performance. Hardware and Software Upgrade – –Addition of up to 10 Ground Monitor Stations. – –Installation of new algorithm developed by the ENRI. The current system uses the algorithm same as IOC WAAS. The algorithm should be improved to adapt to the Japanese ionosphere conditions which are more severe than U.S. and mitigate ionosphere effect. Motivation
