Planet's Advanced Satellite Constellation: A Closer Look
Planet Labs operates a sophisticated fleet of satellites that includes the Dove, SkySat and the next-generation Pelican constellations. The Dove satellites, also known as PlanetScope, form the backbone of their imaging capabilities. These compact satellites, each about the size of a shoebox, are designed to capture daily imagery of the Earth’s landmass with a resolution of 3–5 meters per pixel. This makes them ideal for large-scale monitoring, such as agricultural field analysis, forestry management and environmental assessment.
High-Resolution Imaging with SkySat
SkySats, on the other hand, provide significantly higher resolution at approximately 50 centimeters per pixel. These larger satellites revisit any given location up to 10 times daily, offering unparalleled detail for applications like infrastructure monitoring, disaster response and urban planning.
The Future is Pelican: Next-Gen Satellite Technology
The Pelican constellation represents Planet’s next big leap in satellite technology. Designed as a successor to the SkySats, Pelican satellites aim to achieve an impressive resolution of up to 30 centimeters per pixel, combined with reduced latency in data delivery. This makes them ideal for near real-time monitoring and rapid-response scenarios. The first demonstrator satellite, Pelican-1, launched in 2023, marks the beginning of this new era in Earth observation.
This innovative constellation will consist of 32 SmallSats, with the potential for future expansion. Each Pelican satellite is designed to capture imagery in five bands within the visible to near-infrared spectrum. These satellites will operate in sun-synchronous orbits at an altitude of 475 kilometers.
Geospatial Intelligence Services: Turning Data into Action
In addition to their cutting-edge satellite hardware, Planet Labs offers a comprehensive suite of geospatial intelligence services tailored to meet the needs of various industries. Planet Monitoring provides frequent, medium-resolution imagery that enables users to detect changes and trends over time. This service is particularly valuable for tracking crop health, managing forests, and assessing environmental impacts. For tasks that require highly detailed observations, Planet Tasking offers on-demand, site-specific imagery captured by the high-resolution SkySat constellation. This service is well-suited for disaster response, infrastructure monitoring and event analysis.
Automated Analysis and Basemaps
To enhance decision-making through automation, Planet’s Analytic Feeds leverage machine learning to detect and classify objects or land cover within areas of interest. These feeds are widely used in defense, intelligence and emergency response operations. Another standout product, Planet Basemaps, provides seamless, analysis-ready mosaics created from recent satellite imagery. Basemaps are available in two formats:
- Visual Basemaps: optimized for general visualization, offering cloud-free, color-corrected imagery perfect for urban development mapping, deforestation tracking and GIS applications.
- Surface Reflectance Basemaps: tailored for precise spectral analysis and quantitative tasks.
The Versatile Applications of Planet Basemaps
The use cases for Planet Basemaps are diverse. Visual Basemaps are frequently used for:
- mapping infrastructure,
- monitoring land use changes,
- providing visually consistent data for GIS platforms.
Surface Reflectance Basemaps, particularly the Analytic SR variant, excel in tasks like
- crop health monitoring,
- wildfire burn analysis,
- flood impact assessment.
The Normalized SR variant is invaluable for applications such as land cover classification and forest disease detection.
