When a land-air misile is fired to pursuit a mobil target, quite a few variables play a key role in
order to reach and neutralise the target in no-time. It is desired; nevertheless, this system requires
an amount of time, fuel, real-time data analysis as well as a discriminator system, all these in
order to reach the mobil target. This is why, in this work we present a study for a set of variables
meassured in situ such as: the wind speed, magnetic field, pressure and humidity to generate logs
that can be usuful for either civil and militar applications. The system is designed to meassure in
situ a set of variables starting at 500 m up to 30 km. As a result of this study, all the information
gathered can be feed into the missil main computer and with the info loaded, it can trace
trajectories in which the efficiency of the engine, fuel and cargo reach the target. The low
atmosphere system has the follow set of instruments: a barometer, accelerometer, gyroscope and
a magnetometer as the sensor array. We are using an Intel Galileo board as the motherboard. The
information collected is saved within a SD high density memory card
