GReD, in partnership with Softeco, has designed and started producing GPS permanent stations based on these “mass-market” GNSS receivers and antennas, which allow for cost-effective deployment of sensing networks. About 100 of these stations are already deployed and operationally used by GReD in Italy both for ground and structure monitoring, as well as atmospheric water vapor monitoring.

TWIGA is about to ship 6 low-cost GPS stations to Uganda. These will be deployed in and around Kampala by Makerere University, with the support of GReD, PoliMi and TU Delft. The aim is to establish the first low-cost GPS network in Africa. It will be used to continuously measure the amount of water vapor in the atmosphere. This information will allow to improve forecasts of extreme weather events, such as cloudbursts and thunderstorms.
