The company PlanetiQ plans to use GNSS to make real-time weather forecasts. PlanetiQ plans to launch a commercial weather satellite constellation by 2017, composed of 12 to 18 small satellites that will capture data as GNSS satellites pass through Earth’s orbital horizon. The satellites will use radio occultation to collect data that will supplement computer models on weather, producing more accurate and timely weather forecasts and assessments,... read more

NASA Seeks GNSS Remote Sensing Innovations

December 15, 2014By

NASA is soliciting research on remote sensing techniques that use GNSS for studying the Earth’s environment. Specifically, the announcement says NASA “seeks innovative approaches to the development of Global Navigation Satellite System (GNSS) remote sensing techniques and algorithms to study the Earth’s environment from the ionosphere to Earth’s interior.” The announcement says NASA is seeking to emphasize the use of reflected... read more
