Engineering under hard constraints with repeatable validation and system-level thinking.
Our mission
Mission architecture and measurable objectives
Our core mission is to deliver a modular, redundant sensing platform for operation in high-risk environments. The architecture is designed for scalability, fault tolerance, and clear operational interpretation.
1. System requirements
The system satisfies the mission only when all conditions below are met in parallel.
- enables remote environmental monitoring
- provides real-time telemetry and logged data
- maintains fault tolerance through component redundancy
- supports scaling with multiple networked units
2. Primary mission — environmental monitoring
The redundant design means each of the two onboard computers performs measurements independently.
Feature
Air temperature and humidity measurement
A combined temperature-humidity sensor is positioned to minimize airflow effects and heating from onboard electronics.
Feature
Motion and orientation measurement (IMU)
An IMU unit (accelerometer + gyroscope) provides acceleration and rotation data with a range suitable for descent and landing dynamics.
Feature
Position tracking (GNSS)
Each compute node includes a GNSS module with its own antenna for trajectory tracking and post-landing localization.
Feature
Data collection and network transfer
Data is collected locally and transmitted wirelessly to the gateway. The architecture supports transfer even without direct line of sight.
3. Secondary mission — radiation measurement
An external ionizing-radiation sensor, developed in collaboration with FEI STU Bratislava, is integrated as an independent module.
- sensor is designed as radiation-tolerant
- single-unit deployment reduces complexity and power usage
- radiation data is transmitted over the same network as environmental telemetry
Architecture
CanSat unit as a modular subsystem stack
Core subsystems are structured to support long-term extensibility without breaking the primary telemetry path.
Dual onboard computers
Each node has its own sensors and autonomous capability. If one node fails, the other continues operation.
Integrated sensors
Temperature, humidity, pressure, IMU, and GNSS are present on each computer to provide measurement redundancy.
External payload support
The interface is prepared for a radiation sensor and additional modules without major system changes.
Power subsystem (BMS)
2S battery pack (2x 18650 Li-ion), USB Power Delivery, and solar input with MPPT regulation.
