Abstract

The COMS LRIT/HRIT broadcast service should satisfy the 15 minutes timeliness requirement. The timeliness requirement is an important enough to impact on the overall performance of LHGS. Therefore, the simulation for the LHGS processing was performed with the LHGS prototype in this paper. First, processing time is measured for each process (per modules) of the LHGS without I/O time. Then, the LHGS processing is performed with worst scenario and the processing time is measured. Finally, analyses for processing time and time constraint are performed.
