Due to the huge success of GPS in both military and civil applications, several other GNSSs have been developed, built, and operated in the last few decades. GNSS, regional, and augmentation systems are comprise a growing family that also includes GLONASS, Galileo, BeiDou, and Japan’s Quasi-Zenith Satellite System (QZSS). New members, such as the Global Indian Navigation System (GINS), are preparing to join in next decade.

Vote Nears for Weather Forecasting Bill That Could Boost GPS Radio Occultation Firms

Two companies angling to provide the government with cutting-edge, GPS-based weather data may get a boost this fall if a bill aiming to improve forecasting wins U.S. House approval.

The companies, Bethesda, Md.-based Planet IQ and GeoOptics, Inc., of Pasadena, California, hope to use GPS radio occultation or GPS-OR to provide the National Oceanic and Atmospheric Administration (NOAA) and the Department of Defense with weather data.
