Monthly Station Performance Assessment

Introduction

The ILRS network and station assessment maps are issued each month by the ILRS Central Bureau. These maps reflect the performance of stations based on parameters in the ILRS Pass Performance Standard with additions presented at the 21st International Workshop on Laser Ranging in Canberra, Australia in November 2018. For each parameter, an individual map is created to visualize the network capabilities. In addition, a comprehensive score, based on each of these parameters, equally weighted, is provided for each station on the Comprehensive Score Map. For stations that are not GNSS capable, this restriction has been considered. In addition, some stations focus on LLR tracking and their SLR contributions are appreciated but may be limited. The maps reflect data assessed over the previous 12 months.
