Comparative Analysis of Two Pico Satellites: Performance, Sensor Integration, and Communication Technologies.

In this research, we evaluate the effectiveness of two Pico satellite designs - a can-satellite model and a cubesatellite model - focusing on their performance during controlled parachute descents from a specific altitude. The study centers on embedded sensors in these satellites, which collect environmental and kinematic data throughout the descent. These sensors track temperature, humidity, barometric pressure, gyroscope readings, acceleration, and magnetometer data, offering detailed insights into each design’s descent dynamics. The primary goal is to assess how the can and cubePico satellites withstand descent pressures and their data gathering efficacy during parachute-assisted landings. This evaluation is crucial for understanding how different sensor integration impact the performance and adaptability of picosatellites in freefall conditions. Additionally, the research includes a comparative analysis of two communication devices: the cube satellite equipped with an NRF24L01+LNA, and the can satellite with an ESP32S wireless development board. This comparison aims to identify which communication technology is more suitable for the challenging environment of parachute-assisted descent, with a focus on the reliability and quality of data transmission.
