This poster provides an overview of the design and application of the Ground Segment Performance Model. The model is a discrete event simulation using COTS software and custom libraries and logical blocks, integrated with Microsoft Excel for data analysis. Based on user-specified input parameters, the model simulates product generation from satellite data downlink through Level 0, Level 1b and L2 product generation across multiple sites. The results include average and peak CPU utilization, data storage levels, and latency timing per product.
The Performance Model provides the capability to independently assess performance of the Ground Segment, characterized in terms of product latency, refresh rates, data throughput, storage size, and resource use (computational, storage, bandwidth). The model also supports studies in the architecture trade-space, including processing capacity, bandwidth sizing, and failover scenarios.
