The PA-5 Sodar includes the latest hardware design. The electronics has been down sized by an extensive use of the SMC technology.
The computer part uses an ARM Quad Core CPU which is plugged on a 16 bits A/D converter board. All the hardware matches
military specifications (-40 to +60 °C with up to 100% relative humidity) and is fixed underneath the antenna. Wireless modem or
satellite connections are available.
This new design includes GPS, 2D inclinometer, Wi-Fi, as well as pressure, temperature and humidity measurements
