Utility model content
The utility model is in order to solve at present when aerological sounding highly reaches 25 kilometers, often can not receive the problem of signal, for herein is provided a kind of boat-carrying GPS sounding equipment telemetry system, comprise satellite, sonde, telemetering antenna, telemetering receiver, gps antenna, GPS and terminal, satellite sends signal to sonde and gps antenna, sonde sends signal to telemetering antenna, telemetering antenna is connected with terminal with GPS respectively by telemetering receiver with gps antenna, with by Signal transmissions to terminal, advance signal multiplying arrangement is also provided with between telemetering antenna and telemetering receiver, described advance signal multiplying arrangement comprises low noise amplifier, front bandpass filter and rear bandpass filter.
The utility model boat-carrying GPS sounding equipment telemetry system, described low noise amplifier, front bandpass filter are connected successively with rear bandpass filter, and front bandpass filter is connected with telemetering antenna, and rear bandpass filter is connected with telemetering receiver.The signal received is carried out filtration treatment by front bandpass filter, prevents undesired signal, is filtered by otiose signal, and useful signal directly passes through; Low noise amplifier, for improving emissive power, carries out distortionless amplification to the signal received, and improves the sensitivity received, and reduces reflected energy, strengthens received energy; Then bandpass filter carries out the AF panel of secondary to the signal that low noise amplifier sends, and reduces noise further, better restituted signal, by signal integrity by digital serial port channel transfer to terminal, generation aerological data.
The utility model boat-carrying GPS sounding equipment telemetry system, described telemetering receiver and terminal are placed in indoor, and advance signal multiplying arrangement and telemetering antenna are placed in outdoor, and distance is between the two nearer, and the data received are more accurate.
During sounding, sounding balloon carries sonde lift-off, the weather data situation of atmospheric envelope differing heights is received by the sensor in sonde, the sounding GPS of sonde inside receives the signal that satellite sends, carry out demodulation calculating, obtain positional information and the velocity information of sonde, then the data such as meteorology, position and speed are transmitted to the telemetering antenna of boat-carrying by transmitter, then by advance signal multiplying arrangement and telemetering receiver, the data received are transferred to terminal.And boat-carrying GPS receives the signal that sends of satellite by gps antenna, the positional information of real-time resolving ship is also transferred to terminal.The information that the local position information received according to boat-carrying gps antenna and sonde receive, can also calculate the relative position information of sonde and ship, obtain range information and azimuth information.
The beneficial effects of the utility model are:
The advance signal multiplying arrangement be made up of low noise amplifier, front bandpass filter and rear bandpass filter has been installed additional in the utility model, improve the sensitivity of emissive power and reception, the signal received is amplified, further suppress noise, decrease reflected energy, enhance received energy.Even if the height of sonde is more than 25 kilometers, also can ensure that signal instructions that frequency and oscillograph receive is without clutter, make the accurate data degree that receives high.
