The UltraCam Eagle Mark 3 Digital Photogrammetric Aerial Camera System, owned and operated by Feiyan Remote Sensing, is a large-format high-end aerial survey solution that sets industry standards. Equipped with a 450-megapixel ultra-large footprint sensor and an industry-unique user-exchangeable lens system, it supports flexible switching between four professional lenses (80mm, 100mm, 120mm, 210mm) to adapt to different flight altitudes and resolution requirements. Leveraging the 4.0μm high-sensitivity sensor and non-mechanical high-speed acquisition technology, the device achieves a high shooting rate of 1 frame per 1.5 seconds, delivering ultra-high 1.9cm ground sampling distance (GSD) at 1000m flight altitude. It can synchronously collect panchromatic, RGB, and Near-Infrared (NIR) multispectral data in a single flight. With this equipment, Feiyan Remote Sensing provides high-precision, efficient, and cost-effective aerial data acquisition services for surveying and mapping, infrastructure, ecology, and other fields, significantly reducing operational sorties and time costs.

Technical Specifications

Core Advantages

Flexible User-Exchangeable Lens System：Supports user-independent lens replacement. Four professional lenses seamlessly adapt to low-altitude high-precision acquisition and high-altitude large-area coverage needs. One device meets full-scenario operations without the need to purchase additional specialized cameras.

Ultra-High Resolution & Extreme Clarity：450-megapixel ultra-large footprint sensor combined with 4.0μm high-sensitivity technology, achieving 1.9cm GSD at 1000m flight altitude. Fine ground features are clearly distinguishable, completely eliminating the need for re-shooting.

Synchronous Multispectral Acquisition：Simultaneously captures RGB and NIR multispectral data, supporting pan-sharpening processing to generate high-fidelity color images and vegetation-enhanced false-color images, providing accurate data support for ecological monitoring and crop assessment.

Efficient Operation & Cost Reduction：High-speed capture of 1 frame per 1.5 seconds, increasing single-flight coverage by 30% compared to traditional devices, reducing flight sorties and fuel consumption. The 94% maximum forward lap rate design ensures data integrity while improving operational efficiency.

Stable & High-Precision Output：Strict factory calibration maintains photogrammetric-grade geometric accuracy after lens replacement. 14-bit ADC retains rich image details, delivering uniformly exposed high-quality data even under complex lighting conditions.

User-Friendly Operation Experience：The touchscreen control panel supports real-time in-flight quality inspection. Data formats are compatible with mainstream photogrammetric software, simplifying workflows, lowering post-processing thresholds, and improving project delivery efficiency.

Application Fields

Large-Scale Topographic Mapping & GIS Database Updating：Provides a high-efficiency, high-precision solution for municipal and provincial fundamental geospatial data production and periodic updates.

High-Precision 3D Reality Modeling & Digital Twin Development：Delivers realistic-textured and geometrically accurate 3D reality model data for smart cities, campus management, and cultural heritage digitization.

National & Regional Major Infrastructure Projects：Serves all phases of major projects (expressways, high-speed railways, water conservancy hubs, energy networks)—from survey & design and construction monitoring to as-built mapping.

Natural Resource Asset Inventory & Dynamic Monitoring：Applied in land resource inventory, forestry management, precision agriculture, and eco-environmental change monitoring, providing quantifiable, high-precision spatiotemporal data.

Emergency Mapping & Rapid Response：Can be rapidly deployed after natural disasters or emergencies to acquire ultra-high-resolution current imagery of affected areas, providing first-hand information for assessment, decision-making, and reconstruction.
