<b><span style="font-size:10.0pt;font-family:"Arial",sans-serif">Background</span></b>
<br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">The Functional Resource Model (FRM) defines, in abstract terms, the functions that a ground station performs to provide Tracking, Telemetry and Command (TT&C) services to a spacecraft. The goal is
to arrive at a standard representation of TT&C services, thereby facilitating standards for inter-agency cross support. The functions are organized around logical strata including Aperture, Physical Channel, Synchronization and Channel Coding, SLS Radiometric
Data Production, Data Transfer Services, SLS Data Delivery and Production and others. The functions are defined via configuration parameters, monitored parameters, notifiable events, and associated control directives.
