Nanosatellite missions flying microwave radiometers for high-resolution microwave sounding are quickly proliferating, as microwave instrumentation is particularly well suited for implementation on a very small satellite, as the sensor requirements for power, pointing, and spatial resolution (aperture size) can be accommodated by a nanosatellite platform. Recent advances in low-power millimeterwave low-noise amplifier technologies have been a significant enabler of these systems. The first mission, the Microsized Microwave Atmospheric Satellite (MicroMAS), will demonstrate temperature sounding in nine channels near 118 GHz. MicroMAS is currently onboard the International Space Station awaiting deployment for a 100-day mission. The Microwave Radiometer Technology Acceleration (MiRaTA) cubesat will demonstrate multi-band atmospheric sounding and co-located GPS radio occultation. MiRaTA will launch in early 2016, and will fly a tri-band sounder (60, 183, and 206 GHz) and a GPS radio occultation (GPS-RO) sensor. Both MicroMAS and MiRaTA are 3U CubeSats (aggregates of 10×10×10 cm cubes). We present recent work to develop and demonstrate nanosatellite technologies for earth atmospheric remote sensing using microwave radiometry and describe approaches for transitioning these new technologies into new research constellation missions to provide unprecedented measurement capabilities.
