GPS sonde

Features: Using the saw resonator as vibrator of the signals conveyor system can improve the stability of signal and reduce the bandwidth of communication. That will save most treasured asset His functions for information processing can actualize A/D convert and then perform digital filtering It can reduce noise and improve accuracy The antenna of transmitting module is using the phased antenna without mechanical drive, it has a high reliability Using the alkaline battery as supply power more safe and more environmental protection We use the foam as the packaging and installation in order to conserve the material It can make installation and operation easier Adopts anti-long-wave radiation technology Technical parameters: GPS sonde main performance indicators: Temperature measuring range: -90 to +50&#176C Temperature accuracy: 0.3&#176C Humidity measuring range: 0 to 100%RH Humidity accuracy: 3%RH Pressure measuring range: 5 to 1,050mb Pressure accuracy: 1mb Wind direct accuracy: 3° Wind speed accuracy: 0.3 meter/second Transmitting frequency: 400 to 406MHz Transmitting power: 300mW Channel bandwidth: 20kHz Data rate: 1,200 baud Modulation: FM Transmitting antenna: 1/4λ Ground receiving system main performance indicators: Receive frequency: 400 to 406MHz IF bandwidth: 20kHz IF: 23.05MHz IF: 455kHz Sensitivity: 0.5mV (ratio of signal against noisy is 12) Function: forecast weather and further research on the atmosphere boundary region
