High Performance Multi-Spectral Observation and Real-Time Video Sighting Enabled by NEMO-HD
NEMO-HD is a high-definition, high-resolution earth monitoring and observation satellite with dual optical payloads. These high performance multi-spectral payloads employ commercial off-the-shelf hardware and open source software which enabled the rapid design and development of the mission. Still-imagery is performed through the primary instrument and has five distinct channels covering a 10 km swath, four of which have a ground sampling distance of 5.6 meters and are separated in the following spectrum: blue (420-520 nm), green (535-607 nm), red (634-686 nm), and near infra-red (750-960 nm). The final still-image channel is a panchromatic camera with a ground sampling distance of 2.8 m and captures a spectrum from 400-900 nm. In addition there are two video channels providing high-definition real-time encoded video at 25 frames per second which are co-boresighted with the still imagery channels. This allows for a unique real-time imaging mode in which an operator views a real-time video feed and can command the spacecraft to image a region of interest. The primary video channel has a 5 km swath and a 2.8 m ground sampling distance while the secondary has a 75 km swath and 40 m ground sampling distance. This paper provides an overview of the satellite mission, discusses the design of the instruments, and the mission operational modes, as well as presenting updated status and data.
