' the the ITK lints h TTK and very hose laical ASS lable have demonstrated the advantages in surveys of practical interest to civil engineering based on the use of the RTK technique. These advantages can be summarised as: • increased productivity due mainly to reduced times of initialisation and re-initialisation; • the possibility of surveying in difficult operating conditions with precisions comparable to those obtained with other surveying techniques. At the moment, the only strong limitation to the application of the system seems to be the radius of transmission of the radio link signal. However, if there was the possibility in Italy of working with radio power greater than 1 Watt (e.g. at 35 W as in the USA) or, alternatively, to adopt bands of transmission of the radio signal different from those currently assigned to the system (e.g. the GSM bands), the capacity of communication between the receivers could be increased. This would allow the development of the technique to the point that within a few years it would be a valid alternative to surveying systems based on the use of traditional topographical instrumentation.
