Description:TECHNICAL FIELD
[0001] The present disclosure relates generally to the technical field of meteorology. In particular, the present disclosure relates to an aerodynamically designed radiosonde system incorporating a T-shaped sensor boom for receiving and transmitting weather data.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] A radiosonde, typically by a gas filled telemetry module encapsulated in a weather balloon launched into the atmosphere to receive and transmit meteorological data. Measuring meteorological conditions in atmosphere, a cyclonic storm or a tornado or other atmospheric flows where both the vertical and horizontal dimensions of the atmosphere are of interest. Radiosonde plays a crucial role in atmospheric science, providing detailed and accurate various atmospheric parameters at different altitudes. The data includes wind velocity and temperature data used for navigational purposes. Starting this practice to gather temperature data, thermometers to kites, flying them above earth to get an accurate atmospheric understanding. Later air balloon carrying sensors were used to obtain weather data.
[0004] Conventionally, different sensors mounted on a rectangular PCB called sensor boom were used. The rectangular design of the sensor boom was not suitable as they bring additional drag into the case within stormy or windy weather causing instability and error in measurement of weather data. Also, when pair of sensors were used for cross-references, it failed to provide accuracy and reliability of data due to close mounting of sensors on the rectangular PCBs. Existing radiosonde designs often suffer from limitations related to aerodynamic instability, sensor interference, and susceptibility to environmental factors. Conventional single-boom designs, while simple, can experience significant pendulum motion and oscillations during ascent, leading to inaccuracies in data collection. Moreover, the proximity of sensors to each other and to the processing and transmission modules can result in electromagnetic interference (EMI), further compromising data integrity
[0005] Efforts have been made in the past to address the abovementioned issues. For instance, patent document US20230033142A1 discloses an areological sonde for measuring meteorological conditions in the atmosphere. The areological sonde includes a sonde casing having an outer casing surface and a measurement unit arranged inside the sonde casing. The outer casing surface of the sonde casing is arranged to form a sole drag surface of the areological sonde such that a self-sustaining areological sonde is formed.
[0006] While the cited references disclose a sonde casing having an outer casing surface and a measurement unit arranged inside the sonde casing to measure weather data, but this may cause error in data as the outer casing data and data taken by the sensors may have different values and, there is a possibility to provide a better solution to address the abovementioned issues.
[0007] There is, therefore, a need to provide a simple, lightweight, and cost-effective radiosonde with aerodynamically designed sensor boom to address abovementioned drawbacks and limitations.

The measured noise levels are approximately 37% lower for the T-shaped sensor positioning arrangements 202 compared to single boom sensor arrangements. Further the precise placement of the pressure sensor (202C) at the centre 204 of the horizontal arm 206 reduces its exposure to electromagnetic fields generated by other components, ensuring improved measurement accuracy and reduced interference.
[0048] In an embodiment, the temperature ranges of the standalone temperature sensor (202A) and the combined humidity and temperature (HYT) sensor (202B) are calibrated to an accuracy of ±0.2°C.

The length ratio of horizontal arm 206 and vertical arm 208 includes 1:2. A width of both the arms includes, but is not limited to, 5 cm. The simulations analyzed airflow dynamics around the T shaped radiosonde 100 and a prior art single boom radiosonde during its ascent under varying wind speeds of 5 m/s, 10 m/s, 15 m/s, and 20 m/s. The comparison data of the disclosed T shaped boom 100 and a prior art conventional single boom given in below in table-2.

Drag Coefficient (Cd) 0.85 1.0 15% Reduction
Peak Oscillation Angle (°) 5.5 7.2 24% Reduction

[0053] In an embodiment, the CFD simulations demonstrate that the T-shape boom 200 exhibits a 15% lower drag coefficient compared to the prior art single-boom design. This reduction in drag is attributed to the more streamlined airflow around the T-shape boom 200, particularly at the junction of the horizontal arm 206 and vertical arm 208. Further the T-shape boom 100 also shows a significant 24% reduction in peak oscillation angle and a 50% increase in oscillation damping rate over the prior art single boom. The test results indicate the stability of disclosed T shape boom 200 which returns to equilibrium faster after being perturbed by wind gusts.

After processing and telemetry data generation, the data is modulated and amplified by the radio frequency amplifier 116 to a level by considering the adversities for the transmission as radiosonde required to transmit sufficient power for proper reception of the signals at ground station as high-altitude balloons go up to an altitude of 30 km and during course of ascent ballon may travel beyond 30 km. The data is transmitted using transmitting antenna 114 to the ground station. Transmitting antenna 114 includes, but is not limited to, a monopole antenna configured to provide good gain over the allotted frequency band for radiosonde and minimize back radiation.

receiving by the ground station, a plurality of real-time weather data sensed by the plurality of sensors (202) configured on the T-shaped sensor boom (200) and transmitted by the radiosonde system (100); and
analysing and processing received real-time weather data by the ground station for navigational purposes.
