Purpose & Contents
Tether sonde attached to flight balloon by dereeler is an equipment for the research of measurement of boundary layer of atmosphere and measures temperature, relative humidity, pressure, wind speed and win direction of atmosphere.

The target is developing equipment that measures vertical distribution by controlling altitude of observation sensor at the specific time interval and analyze thermodynamics of atmosphere up to altitude of 1.5km.

The aim of research “Research Development of tether sonde” is the development of system with tether sonde which could analyze lower atmosphere under 1.5Km altitude intensively.

Results
○ Ground System Development for Tether sonde
· Development of Temperature, Humidity, Pressure, Wind Speed and Wind Direction Sensors for Tether sonde

- Temperature sensor
It is using the same element as NTC type sensor as radiosonde for upper air measurement and has quick response characteristics.
It is measuring not only temperature but also improving the error that happens as temperature is getting down and is correcting with reference temperature which is not affected by the measurement circuit.

- Humidity sensor
It is designed the same element as Capacitive Polymer type as radiosonde for upper air measurement
Capacity value is changed by humidity condition and the value is converted to frequency by analog comparator.

- Wind direction sensor
it is generating the output by compass direction that the wing of tether sonde is rotating by wind direction and can monitor the status of geomagnetic by 3-axis compass.
It is ultra small size and high flexibility of arranging component by MEMS technology.

- Wind speed sensor
It is measuring wind speed by propeller type wind sensor.

- Pressure sensor
It is using capacitive type pressure sensor and has the same type of Capacitance type as humidity sensor and the value is changing by pressure variation.

· Development of ultra-low power consumption two-way wireless communication module.
It is implemented with two-way radiosonde and one-chip integrated circuit by optimizing and merging the existing components for the measurement and transmission circuit.

· Receiving System
It is composed of GPS Antenna, GPS Receiver and is receiving the GPS coordinate from tether sonde.

· Tether sonde flight equipmen
It is using light weight type of EPP styrofoam for the body, carbon fiber for main pipe and wood-lock coating for wing and is durable.
for hanging on tether sonde, the pipe is designed with aluminum pole to resist against the force of up and down from tether sonde.

· Operating software development
- display data by the time and altitude.
- automatic input of calibration data of each sensor.
- automatic searching of receiving frequency

○ Implement of Test Environment and Evaluation of tether sonde
· Heli-Kite Operation
Heli-Kite is flight device mixing balloon filled with Helium gas and aerodynamic kite.
the float force by wind is higher that the one of balloon filled with helium and also
it is operating under any weather conditions by mixing aerodynamic and aerostatics

Expected Contribution
Expect Real-time wind profile, flux measurements, boundary layer wind data, fire weather, pollution monitoring and emergency response effects by analyzing the lower atmosphere of 1km above the ground intensively.
