Optics must withstand extreme conditions and have perfect coverage for accurate image reproduction without distortion. Requirements for OpticsĮarth imaging market has high requirements for camera lenses. Unlike radar remote sensing, satellite camera technology only captures images from the Earth's surface, while imaging quality depends on lighting, weather conditions, and cloud cover.ĭragonfly optical payloads are designed for smallsats (50-150 kg) and CubeSats 1 – 6 U with orbit heights up to 500 km, making captured imagery useful for a wide range of commercial and scientific applications. Application of Satellite Optical PayloadsĮarth Observation satellites with optical payloads help track changes in forest and water covers, melting glacier levels, soil conditions and yield, make geographic maps, prevent emergency consequences, monitor transport routes, GSD depends on camera specificationĭragonfly cameras provide multi- and hyper-spectral high resolution imagery with up to 0.7 m GSD (in nadir, at an altitude of 500 km). It determines the smallest size of an object that can be seen in the image. Ground Sampling Distance (GSD) is another important parameter of a satellite camera. Hyperspectral, simultaneously capturing narrow spectral zones in all parts of the spectral range.Multispectral (multizone), ranging from visible to infrared electromagnetic radiation.Satellite cameras allow to get the following images: And the simplest example of an image captured by a such system is Google Maps. Sun is the most vivid example of such an object. In fact, a satellite imager is a detector with a sensor that actively scans the changing surface of the Earth, registering the signal emitted or reflectedīy the object or the surrounding area. Satellite camera systems capture space in a wide range of electromagnetic waves.
