Objectives and Applications
|
PlanetiQ was formed to build, launch and operate the first commercial constellation of GNSS-RO (Global Navigation Satellite System-Radio Occultation) weather satellites, with 20 LEO (Low Earth Orbit) satellites to be deployed. The overall objective is to introduce innovation to satellite weather observations. For this reason, PlanetiQ’s satellites will carry the fourth-generation “Pyxis” radio occultation (RO) sensor. Pyxis builds on the heritage of the gold standard for RO sensors. The PlanetiQ team has developed and built the previous three generations of RO sensors proven on orbit, including 20 flight units for prior, current and upcoming satellite missions.
