The Tests: Single Point Fidelity Hypothesis

To Show Data Fidelity Even w/ Extreme Testing Test Setup

System, Single Spot on Football Field, Cold, Cloudy Metrics

Latitude, Longitude, and Satellite’s Found Workload

Poll System for Data 20 Times at a Polling Rate of 3/Minute Parameters

Shielding, Position, Speed, Weather Test Run

The Tests: Path Fidelity Hypothesis

To Show Movement and Quick Direction Change Do Not Effect Fidelity

Test Setup System, Path on Football Field, Cold, Partly-Cloudy

Metrics Latitude, Longitude

The Data:General

On Average 6 Satellites Found

Distances from Path have Low Variance of only a few feet

Outliers account for less than 3% of the data

Author: Nicholas Brockmeyer

Conclusion

Data Fidelity within bounds for both tests (within 150 feet)

Latency to poll is << than the shortest polling time we plan to have available.
