BEST is an engineering company developing remote sensign instruments for environmental observations. Our sensors, microwave radiometers, also knownas passive microwave sensors, are very good at detecting water and its phase (ice, snow, liquid) in the environment. This capability provide very unique information about weather and climate. Microwave radiometer can observe through clouds and precipitation. This makes them very valuable, all weather instruments, capable to observe, for example, rain rate, cloud properties, surface moisture, ocean surface wind vector and more. We are building unique instruments to our clients specification. Our deployable offset parabolic reflector antenna is the only antenna on the planet capable of operating up to 100 GHz. We are develeping a 200 GHz model now.
