High-Level Project Summary
Space Loon Project encourages the student community, both the school body and the university, to create their own scientific high-altitude balloons (HAB) in order to explore aerospace media in a better way and, with this, to be able to measure the concentration of ozone, pollution, temperature, humidity, etc. Besides, to implement these data acquired in future investigations of their communities and nearby. Also, the benefit of using Arduino, raspberry and low cost components, give us an advantage to arrive in location that couldn't finance more expensive meteorological projects, this because we build our own transmitter and reception for implement meteorological data base and reception soft

Detailed Project Description
Well our project, we have relied on the arduino system to capture sensors which tranmit a few signal which is sent with a serial radio packet format at 9600 bps, at the input of a fsk modulator, using the XR2206 chip, whose signal at 9600 baud enters a Colppits type transmitter, which is tuned to 138 Mhz with radio frequency power 2.2W. Also, the transmitter signal that enters a dipole antenna, these radio frequency signals are transmitted to the reception station, where they are received by Yagi antennas, which enters a receiver that we have built, and at its output it enters a fsk demodulator made with the XR2211 chip, which It is connected to the serial port of the computer in which there is software that stores and graphs the data from the radiosonde sensors. On the other hand, the benefits that we can acquire with this project are that, it will be an educational platform to investigate the stratosphere because the students will be able to put the sensors that the experience requires and they will be programmed by themselves. On the other hand, we want to arouse scientific interest and give the message of "I did it by myself." Finally, the arduino UNO board was used, the Raspberry Pi, the manufacture of a fsk modulator, the manufacture of a transmitter in fm, the manufacture of a receiver also in fm, the manufacture of a demodulator fsk, the C ++ language, the language Python.

Andros Island Rawinsonde and Radiosondes
INSTRUMENT DESCRIPTION
Two basic instrument types are flown
- Rawinsonde with GPS winds and Loran-C winds
- Radiosonde with chilled-mirror sensor
A radiosonde is an instrument carried into the upper atmosphere by a balloon that measures pressure, temperature, relative humidity vs. time. A rawinsonde is a radiosonde tracked by navigation aids from which winds can be calculated. The sensor measurements are transmitted to a ground receiver where they are processed to provide heights and other information, as desired. Winds are measured using a navigation aid technique such as Loran-C or GPS. The radiosondes used at Andros Island are mostly GPS type radiosondes using full code-correlated transmission from up to 10 GPS satellites. This provides accurate height and wind information allowing pressures to be calculated. A smaller number of radiosondes use Loran-C. Because of the location of Andros Island relative to the Loran-C transmitters little wind information is expected from this technique. The GPS and MK-2 radiosondes typically use a carbon resistive relative humidity sensor. A limited number of chilled mirror type radiosondes will be used to obtain more accurate relative humidity profiles. These chilled mirror instruments represent the mating of an old technolgy process with a new application - accurate chilled mirror measurements using an inexpensive radiosonde.
Hackathon Journey
An interecting intervention of the NASA staff persons thats give us the tools to develop a good work and guide us with livestream videos, and conferences. On the other hand, I learned to size the activities of a research project with a scientific method (trial and error), with the challenges proposed by NASA. Also, the inspiration to choose this challenge was because a university professor. In addition, the objective of this project was to students to develop their projects themselves with hardware tools and free software. Also, the setbacks were solved with emphaty and group work. Finally, we want to mention the sacrifice of our parents to be able to have the hardware at hand and in addition to giving us support in the face of adversity, thank you to them.
