INTRODUCTION

The ability to effectively conduct NAVWAR modelling and simulation is a great asset to the warfighter. These tools can be utilized to quickly run different scenarios and assess the effect of GNSS interference on fielded navigations systems. This, in turn, enables mission planners to modify or generate mission plans according to this data. The model described in STANAG 4665 can be implemented at Basic or Enhanced levels. The anticipated fidelity is a function of its complexity. The model must undergo a validation process in order to:

1) Determine that the underlying theories and assumptions used in the model have been correctly implemented.

2) Indicate to the user the degree of fidelity of the model.

The model validation process is an extensive task in which real-world data is compared to model outputs. A frequent cause for model validation failure is that real-world "truth" data itself is not valid. This document will describe the standard test scenarios and data collection techniques to ensure that the data is sufficient, accurate and appropriate to use in the model validation process.
