In this system, fire fighting airplanes can outline the areas on fire and inform the rescuers regarding tree species, terrain, and the onsite situation of the on-fire area, which is illustrated in Figure 8. Inspection and Monitoring System for High-voltage Power Line in Remote Areas The inspection and monitoring system for the 500-kilovolt power transmission line, which extends about 3,000 kilometers in total and has 4,000 inspection FIGURE 8 COMPASS forestry fire prevention system.

Also in 2010, intelligent upgrading of 23,500-kilovolt stations of the East China Power Grid was completed successively. By taking advantage of highaccuracy timing services provided by COMPASS, both the accident rate caused by timing accuracy and the malfunction rate of sampled facilities are zero, exceeding the internationally accepted standards.
