Vaisala Radiosonde RS92-AM
P(Y)-Codeless GPS
The Vaisala Radiosonde RS92-AM has a GPS receiver which is independent of the GPS C/A-code signal. [. . . ] The digital transmitter also consumes less power than analog transmitters and more channels are available in the meteolorogical frequency band.
CAL-4 Calibrated
The RS92-AM's PTU sensors are calibrated in the CAL-4 calibration machine. Designed by Vaisala and built in-house, CAL-4 is the world's most advanced calibration machine for the mass production of PTU sensors.
Features
P(Y)-codeless GPS technology for continuous wind data availability A higher level of PTU measurement performance Stable transmission complies with ETSI standard EN 302 054
