Research Partnership Expands Aircraft Tracking Coverage

We are excited to announce a new research partnership with the Aviation Data Consortium that significantly expands our aircraft tracking coverage across the Pacific Northwest. This collaboration brings together multiple independent receiver networks to create a unified dataset covering over 500,000 square miles of airspace.

Why Partnerships Matter for Coverage

Aircraft tracking networks face a fundamental challenge: radio signals travel in straight lines and cannot penetrate terrain. A single receiver station can only monitor aircraft within line-of-sight range—typically 150 to 250 nautical miles depending on altitude. Mountains, buildings, and the curvature of the Earth all create blind spots.

By partnering with other tracking networks, we can pool data from dozens of receiver stations positioned strategically across the region. An aircraft invisible to our primary station might be clearly visible to a partner station 200 miles away. When we combine these datasets, coverage gaps disappear.

What This Means for Users

Starting this week, our coverage maps show dramatically improved continuity across previously problematic areas. Commercial flights traversing the Cascade Mountains no longer drop off our tracking displays. Low-altitude general aviation traffic in rural areas now appears consistently in our database.

The expanded coverage also improves our ability to track historical flight patterns. Researchers studying aviation trends can now access complete flight paths instead of fragmentary data with gaps. Airport planners can analyze traffic flows with confidence that the dataset captures actual activity rather than just the portion visible to nearby receivers.

Technical Implementation

Integrating multiple data sources presents interesting technical challenges. Each partner network uses different receiver hardware, antenna configurations, and decoding software. Signal quality varies. Timestamps might be slightly offset between systems. Aircraft might appear in multiple datasets simultaneously.

We developed a data fusion pipeline that normalizes incoming position reports, eliminates duplicates, and creates a unified track for each aircraft. The system automatically detects and compensates for systematic timing offsets between partner feeds. Position reports are weighted based on signal quality and geometric dilution of precision.

Growing the Network

This partnership is just the beginning. We are actively working with additional aviation tracking groups across North America to expand coverage even further. If you operate ADS-B receivers and want to contribute to this collaborative effort, contact us about joining the Aviation Data Consortium.
