Two experiments were carried out to launch stratospheric probes where both had sensors and some individual particularities to validate long-distance data transmission through LoRa. The first probe reached a maximum altitude of approximately 31 km and managed to transmit an image loaded on it, the second probe reached a maximum at approximately 15 km but had an on-board camera that allowed a photo to be taken and transmitted successfully, it is also worth mentioning that both probes were launched in partnership with the Alcântara Launch Center (CLA). Below are some photos from launch day and the one taken by the second spacecraft with a comparison taken from Google Earth.
