Project Overview
Bahallo is a student CanSat mission developed by ASPiRE for the CanSat in Greece 2020 competition, which is designed to simulate a real satellite mission end-to-end—from design and testing to launch, telemetry, and data analysis. The CanSat is carried aloft by an organizer-provided rocket (similar in concept to a “Patriot” model) and released at about 1 km altitude, after which it descends under its own parachute to enable safe, controlled data collection and recovery. During descent, the primary mission is to measure key atmospheric and navigation-related quantities—such as temperature, atmospheric pressure, and geographical positioning/trajectory data—store them onboard, and transmit them in real time to a ground station for continuous monitoring. The secondary mission is built around a practical emergency-response idea: estimating the position of a “beacon” (a signal source) using triangulation. At low altitude (approximately 70–50 m), the CanSat separates into four parts—three ground “nodes” and one beacon—forming a small ad-hoc network on the ground that uses the received signal to infer the beacon’s location. The mission is considered successful if reliable telemetry and logging are maintained, the descent and separation occur as planned, and the system is recovered intact, with the separated parts landing within a reasonable area for retrieval.
