Waltr FAQ

For airports and ports, we use our patented ground-based imagers. Our algorithms process images in real time, detect emission sources, and analyze dispersion.
For cities and territories, we use a combination of spatial imaging (satellites), atmospheric modeling, and artificial intelligence to identify, quantify, and map greenhouse gas and air pollutant emissions.

Depending on the technology used, image resolution varies. For example, ground-based imaging provides high resolution (a few tens of centimeters/a few seconds), while satellites offer a wider view but with lower resolution (a few kilometers/a few days).

Waltr provides near real-time updates and periodic reports on the data collected (e.g., hourly or daily).

Our algorithms incorporate tested and validated models that take into account lighting, weather conditions (clouds, rain, fog, bright sunlight, etc.), and even the viewing angle of each camera. We also train the AI to improve its resilience to varying weather conditions.

Yes. Waltr offers APIs so that data can be integrated directly into management systems at airports, ports, or cities, for example. We also ensure compatibility with data security standards.

Waltr applies high IT security standards (encryption, secure storage, and controlled access). We comply with applicable legislation in France, Europe, and internationally. Sensitive data can be anonymized as needed. In addition, we conduct regular security audits.

To install our cameras, we need an electrical connection and access to the communication network. Waltr assists its customers and partners in sizing the necessary equipment according to the size of the infrastructure and the desired measurement frequency.

Waltr offers "full service" in some of its packages for the convenience of its customers and to combat planned obsolescence. We carry out regular preventive maintenance on our cameras and update our software. Waltr has teams dedicated to technical support, performance monitoring, and on-site intervention in the event of an incident.

Waltr solutions provide immediate visibility into your emissions, environmental performance, turnaround management optimization, and on-site safety compliance.

Waltr solutions enable infrastructures to better understand their impacts and act more quickly and accurately thanks to the reliable, continuous, and contextualized data we provide.

This operational transparency facilitates decision-making, strengthens internal communication, and improves stakeholder confidence.

For airports, Waltr is a comprehensive and integrated operational management tool.

Our technologies enable real-time tracking of aircraft positions at the airport, emissions associated with engines and APUs, and safety indicators such as vehicles crossing runway lines.

Airports equipped with the Aircraft Emission Tracker solution have seen improved operational efficiency, reduced pollutant emissions, simplified regulatory compliance checks, and easier use of our data for reporting purposes.

In addition, the independent data provided by Waltr strengthens the relationship of trust with airlines, local authorities, residents, and various stakeholders, thereby contributing to a positive and responsible image for the airport platform.

Waltr enables airlines to reduce their fuel and maintenance costs on each rotation. Waltr enables airports to optimize their investments in PCOs and reduce operating costs on each rotation.

Savings are measured and visualized in real time using APIs, dashboards, and the Waltr platform.

Waltr automates the collection, verification, and reporting of data required for climate-air-energy plans (PCAET) and carbon footprint assessments.

The indicators are calculated in accordance with European regulations and can be integrated into reports intended for the authorities. This approach simplifies the implementation of regulatory obligations, reduces the administrative burden, and ensures complete data consistency between the various stakeholders.

Yes. Several airports, ports, and local authorities already use Waltr technologies.

Deployment is carried out in several stages, which may vary depending on the infrastructure, its size, and specific requirements:

1. Diagnostic stage to define the areas of implementation

2. Installation of Waltr systems

3. Data flow configuration

4. Training AI models

5. Training your teams in the use of our APIs and data

6. Data transmission and alert setup

7. Change management support for rapid and long-term operational adoption

It depends on the size of the infrastructure and the scope to be covered. Commissioning can take up to a month for a full deployment.

Waltr provides dedicated resources who work with technical and operational staff. We set up training sessions, workshops, and on-site follow-up to ensure that data is translated into concrete actions.

Yes. Waltr is implemented on infrastructures in France, Europe, and other regions of the world. Our international team can install and provide support for our solutions in various international regulatory contexts.

The cost depends on the scope of the analysis and the services selected. Waltr offers customized services tailored to your needs. We can provide you with a quote upon request after discussing your requirements with you.

The data we provide can be used as a basis for regulatory reporting and to verify compliance with internal policies or environmental labels.

Yes. Our data is recognized by certain regulatory authorities: 

• Approved Air Quality Monitoring Associations (AASQA)
• The air quality laboratory
• The General Directorate of Civil Aviation (DGAC)
• Air Transport Safety (STAC) in France.

We have internal quality control for our data. At the same time, our data is also validated by the air quality laboratory and by regulatory bodies such as the Approved Air Quality Monitoring Associations (AASQA).

We constantly monitor local, European, and international legislation and stakeholder expectations. Our technology, algorithms, and reports are updated in line with these developments.

Waltr generates alerts and identifies sources of abnormal emissions so you can quickly take effective corrective action.
