This paper assesses real time ZTD estimation with postprocessing results. For the AGNES network, the absolute ZTD as well as the differential values between the reference stations were compared. The analyses show that 1 cm accuracy for absolute ZTD and 7 mm for relative ZTD can be achieved in real time...
