PREWAM is a viable alternative to high-grade geodetic receivers, whose high cost, is prohibitive for their deployment in the form of dense networks for the purpose of PWV estimation on a high spatial resolution.
Takes fully advantage of all current operational GNSS satellite systems (GPS, GALILEO, GLONASS and BeiDou) to exploit the maximum possible number of GNSS satellites for accurate PWV monitoring
Constructed by 3D Printing technology ensuring durability in outdoor environments.
