GPS Radiosonde

The digital Radiosonde offers high level of PTU and wind measurement perfermance, excellent Data availability and quality with error detection. The digital transmitter also consumes low power and occupy narrow frequency band. The frequency of radiosonde can be tuned continuously among the meteorological frequency band to avoid being interfered by another same frequency signal.
