Airspace logistics cleared at Canadian international airport

Airspace logistics cleared

Volatus Aerospace, a global aerial solutions provider, is ushering in a new era of logistics by integrating cargo drone operations into the controlled airspace at Canada’s Edmonton International Airport (YEG). The success of this groundbreaking project hinges on the centimeter-level precision and reliability provided by the Trimble PX-1 RTX® from Trimble Applanix.

Volatus, which offers aerial solutions across sectors including energy, infrastructure and mining, began using the Trimble Applanix technology in 2022, seeking a high accuracy positioning solution for precision flying and landing. The company leveraged the Trimble PX-1 RTX, a small-form-factor GNSS-inertial solution that delivers real-time centimeter-level accuracy without needing local base stations, thanks to the Trimble CenterPoint® RTX correction service.

Overcoming key challenges in scalable drone logistics

The Edmonton International Airport project is a multi-phase endeavor focused on establishing a scalable drone logistics network for time-critical, high-value cargo such as medical supplies. The project presented some key challenges, including:

• Precision landing without infrastructure: Landing a drone autonomously near terminal buildings or hangars is difficult and traditionally required setting up a local RTK base station, which is time-consuming and difficult to manage across a massive airport complex.

• Runway approach safety: To cross an active runway glide path, the drone must maintain a strict ‘virtual corridor’. Even a small deviation in height or location could interfere with commercial aircraft.

• Environmental and datum obstacles: Standard RTK accuracy degrades over distance and runs the risk of datum shifts. Additionally, vision-based camera systems can fail in low light or weather conditions, requiring landing pads to be kept perfectly clean.

The PX-1 RTX overcomes these failure points through advanced sensor fusion. It delivers positions in a consistent, global reference frame (ITRF) with consistent accuracy across any distance and acts as an all-weather solution that does not rely on visibility.

Soaring to new heights

The first phase of the project successfully completed over 3,000 commercial drone flights at YEG, covering over 8,500 kilometers. The second phase then marked a Canadian ‘first’ by safely integrating a drone flight to intersect within the active runway glide path. All flights are controlled remotely from a centralized Operations Control Centre, showcasing a highly efficient and scalable workflow.

The project directly supports healthcare delivery for the Montana First Nation, located south of Edmonton. By establishing a reliable drone delivery route, Volatus can transport time-critical medical supplies—such as lab samples and prescriptions—between the airport and the community, bypassing road traffic and winter weather delays.

Across the board, the YEG project is a powerful demonstration of how high-precision positioning enables autonomous, safe and commercially scalable air logistics, proving the efficiency and reliability of drones in highly regulated airspace.

Key benefits of the PX-1 RTX

• Support: Access to expert technical guidance during integration.

• Advancement of technology: Moving away from bulky ground gear to a streamlined, satellite-based system that ‘thinks’ faster than standard GNSS. It is a resilient solution against multipath in urban areas for near-building operations.

• Precision: Achieving the ‘gold standard’ of accuracy required by aviation authorities for flight in regulated airspace.
