Vaisala Radiosonde RS92-AM for defense use

Vaisala radiosonde RS92-AM is for defense customers who have access to Precise Positioning Service (PPS) GPS receivers. RS92-AM radiosonde wind finding is based on the measurement of Doppler shift of the GPS P(Y) code frequency. It ensures high data availability using P(Y) codeless wind finding technology without using Standard Positioning Service (SPS) GPS signal. The use of SPS can be denied during an international crisis, which does not affect the use of RS92-AM radiosonde.
