Objectives of the Product

Twinspector is designed to provide reliable and independent access to very high-resolution satellite imagery that helps utilities better understand and manage critical infrastructure and the environment.

The product addresses a growing need for timely, accurate and scalable information to monitor assets such as railways, power networks, pipelines and surrounding land areas, especially as infrastructure systems become more sensitive and exposed to environmental and operational risks.

The primary objective of Twinspector is to deliver consistent and very high-quality Earth observation data that enables early detection of changes, supports risk assessment, and improves decision-making for infrastructure operators and public authorities.

By offering both standard and three-dimensional stereo imagery, the product allows users to gain deeper insights into terrain, vegetation and asset conditions over large geographic areas.

Customers and their Needs

Twinspector addresses the needs of infrastructure operators and public-sector organisations that rely on continuous, accurate and scalable geospatial information to manage spatially distributed assets.

Primary customers include operators of linear infrastructure such as railways, electricity transmission and distribution networks, pipelines and transport corridors, as well as national and EU authorities responsible for infrastructure oversight, environmental monitoring, and regulatory compliance.

Infrastructure operators require regular access to very high-resolution optical imagery to detect small-scale changes, assess risks, and monitor asset conditions along narrow corridors over large geographic areas. Stereo imagery and three-dimensional information are essential to support height-related risk assessment and vegetation-related hazards.

Customers also require predictable revisit rates, consistent imaging conditions, and reliable long-term data availability to integrate satellite-based insights into operational planning and maintenance workflows.

Across all customer groups, seamless integration of data products into existing geospatial systems and long-term service continuity are key requirements for sustainable operational adoption.

Targeted customer/users countries

Europe (including Germany and wider EU/EEA), United Kingdom, North America (USA/Canada), and selected growth markets (e.g., Asia-Pacific, including Australia and Africa).

Product description

Twinspector is a dedicated Earth observation mission based on two identical optical satellites flying in a trailing formation, enabling the acquisition of very high-resolution mono and stereo imagery for infrastructure and environmental monitoring. 

The product offers panchromatic imagery with sub-meter spatial resolution (≤ 50 cm GSD) and multispectral imagery with meter-scale resolution (≤ 2 m GSD) across four spectral bands (blue, green, red, near-infrared). Stereo imaging is enabled through controlled off-nadir acquisitions with defined stereo geometry, supporting the generation of three-dimensional information products, such as Digital Surface Models, with high geometric consistency. Typical swath widths of > 14 km allow efficient coverage of narrow corridors and long linear assets.

Intelligent onboard processing clips imagery to the corridor Area of Interest and applies cloud masking to reduce downlinked data and accelerate delivery.

On ground, the processing chain produces analysis-ready products (including stereo-derived 3D information) that feed LiveEO’s risk analytics services (Treeline and SurfaceScout). Users interact via a web application and API, with export formats (e.g., geospatial layers and reports) for integration into enterprise asset and work management systems.

Added Value

Twinspector strengthens the value of LiveEO’s existing analytics products, Treeline and SurfaceScout, by providing a dedicated and reliable source of very high-resolution mono and stereo satellite imagery tailored to infrastructure monitoring needs. Treeline supports utilities and railway operators in identifying vegetation-related risks along linear assets, while SurfaceScout focuses on detecting third-party activities, terrain instabilities, and other threats in the surrounding environment.

By ensuring predictable data availability and consistent imaging conditions, Twinspector significantly increases the scalability of these products, allowing customers to monitor larger networks more frequently and with greater confidence.

By reducing dependency on manual field inspections and emissions-intensive aerial patrols, Twinspector helps lower operational costs, improve safety for field personnel, and support more sustainable infrastructure operations. As a dedicated and scalable data source, Twinspector strengthens the long-term reliability and continuity of LiveEO’s services, enabling customers to embed satellite-based insights into routine asset management workflows.

Current Status

The Twinspector activity is in the definition phase. User needs, mission objectives, and system-level requirements are consolidated and aligned with LiveEO’s existing products and target use cases. Initial concepts for the space and ground seg-ments, including stereo imaging and data processing, are defined, providing a solid basis for progressing into detailed design and implementation.

Current work focuses on system engineering, risk management, and procurement planning for critical payload and platform elements, including long-lead items. Coor-dination between the prime (service and mission owner), platform supplier, payload supplier and electronics partner is established to ensure consistent design and veri-fication approaches across the space segment.
