The goal of this project is to analyze the usefulness of different clock models for NTP, contributing for an enhanced performance. The goal is to use filtering techniques to analyze 2 issues. The first is a parameter that provides an explicit connection between the polling interval and the accuracy of the synchronization process. The second issue is a more sophisticated model for the performance of the clock on the local system and for the network delay.

- Write a program that computes the Allan deviation of a local clock using the NTP data as the time differences. The NTP data would not adjust the local clock, so that the result would be the statistical performance of the combination.
- Graphical representation of the data.
- Run the estimator for about a week.
- GUI Development
- Calculate the Allan Deviation, the Histograms, the Residuals
- Eliminate Bad-Measurements using the Allan Deviation of the Middle of the Data

- Explanation of the results obtained. Small Report to Dr. Levine
