The Maia S2 is a 9 channel multispectral sensor with bands aligned to the Sentinel-2 satellite system. The Maia-S2 allows us to map the earth's surface at very high resolution (cm and even sub-cm level) using the same spectral bands used by the Sentinel-2 satellite system. This provides a great tool for understanding the sub-pixel variability within Sentinel satellite data, as well as a very versatile and scalable multispectral capability in its own right. All bands lie within the Visible-Near Infrared range.

Platform compatibility We have Maia S2 integrations for the following platforms: DJI Matrice 300 RTK on damped fixed mount DJI Matrice 600 Pro platform using a Ronin-MX gimbal for camera stabilisation. Additional UAS and manned aircraft platforms are possible with additional integration time. Status and availability We have 1 unit available. Additional Maia-S2, and Maia-WV sensors are available through the NERC FSF facility. This article was published on 2024-06-25
