New to CubeSat.gr? This guide explains how to use the workspace to design your mission.
Quick Start
Welcome to the CubeSat Engineering Environment. This workspace is divided into several specialized modules, each focusing on a specific aspect of nanosatellite design. Follow the modules in order from top to bottom to build a complete mission architecture.
Module Reference
Define the physical size of your satellite (1U, 2U, 3U, 6U) and its material. This establishes the mass and volume constraints for all other systems.
Select and add technical components like On-Board Computers (OBC), Communications (UHF/X-Band), and Power Systems (EPS). Each part adds mass and consumes power.
Switch to X-Ray view to see how components are stacked inside the chassis. This module helps you visualize the internal organization of your satellite.
The most critical engineering module. Monitor if your total mass exceeds launch limits or if your subsystems consume more power than your solar panels can generate.
Select your target orbit (LEO, SSO, ISS). Orbit choice affects communication windows, radiation exposure, and how much sunlight your solar panels receive.
Step-by-step technical breakdown of how to physically assemble the selected components. Essential for hands-on educational purposes.
Generate a professional technical PDF summary of your entire design, including mass/power budgets and subsystem specifications.

Interactive Development Roadmap (12-Month)
Click on a development phase below to explore key milestones, standard aerospace reviews, and physical testing campaigns.
Reviews: MDR (Mission Definition Review)
Trade studies on orbital targets, communications links, and thermal envelopes. Preliminary Commercial Off-The-Shelf (COTS) components matching our mechanical budget are locked in.
Real-time 3D tracking of satellite constellations.
Launch the interactive 3D tracker to visualize live orbital data for major satellite constellations.
Define the CubeSat form factor and structural configuration.

Mass Analysis
Power Analysis (Orbital Avg.)
Calculations use dynamic eclipse periods from the Orbit module and assume 28% solar cell efficiency.
Volume Utilization
Data & Telemetry Budget
If net accumulation is positive (+), data is generating faster than it can be downlinked, eventually filling the OBC storage.
Constellation Lifecycle Cost (5-Year)
Pricing estimates include standard COTS hardware BOM, Launch integration (~$35k per U), bulk manufacturing discounts, and ground operations support ($20k/year per active orbital plane).
Define orbital parameters and environmental conditions.

Active Warnings
Run a check to see warnings.
AOS / LOS: Acquisition of Signal (AOS) only occurs when the satellite flies directly over a Deep Space Network (DSN) ground station (orange triangles). Otherwise, the satellite is out of contact (LOS).
Battery (EPS): Drops during Eclipse, recharges via solar arrays in sunlight. SOC tracks charge state.
Thermal (TCS): OBC and battery temps rise under heavy power draw; drop during eclipse cold-soak.
COMMS: RSSI and SNR degrade near the horizon. Doppler shift reflects satellite closing/receding speed.
PDH Buffer: Payload data fills the Mass Memory during LOS, and rapidly dumps to ground stations during AOS passes.
