1 INTRODUCTION

The WVBS is designed to support ground operations training and mission control planning activities for the WorldView program. It may be used in a standalone mode to provide simple Command and Telemetry interfaces for operator training. In this capacity, the WVBS uses internal models to provide its own data sinks and sources for the closed loop simulation of the WorldView Bus operations.

To provide higher resolution mission simulations and to provide extended support for additional mission operations activities and training, the WVBS is used in conjunction with the PLS.

1.1 Scope

This Interface Control Document (ICD) defines the data interfaces between the WVBS and the PLS models developed for the [**Redacted**].

Input and Output specifications for the data products are derived from the references listed in Section 2.1.

Driving requirements identified in this document either come directly from the WV3 Satellite Simulator Specification, Doc # 10258368 or are derived from that document.

1.2 Purpose

This document is intended for use by developers and implementers of the PLS and PLS to WVBS interface. For each external PLS model, the structure and content, frequency and method of delivery of all input and output data products is defined.
