Differential GNSS devices such as the GW16143 are starting to replace survey-grade equipment. Other radio cards such as the Gateworks GW16130 Iridium Satellite Modem or GW16132 CAT-M1 modem can provide communication links for the augmentation data. The GW16143 enables precision navigation and automation of moving machinery in industrial applications such as agriculture, mining, and field mapping.
