Validate your satellite on Earth as if it’s already in orbit
Identify critical software integration issues before launch. Run automated mission tests on real CubeSat or small satellite with emulated orbital sensors — no expensive lab required.
Orbit is the wrong place to fix bugs
- Space missions fail due to late hardware-software integration
- Real sensor behavior is hard to reproduce on the ground
- Embedded systems are increasingly complex
- In-house "Hardware-in-the-Loop" labs are expensive to build
- Manual testing is unrepeatable and prone to human error
Mechanical systems are rigorously tested. Embedded systems are not!
Virtual Orbital Lab
TestNest connects your real satellite hardware with our cloud-based simulation platform. We feed your hardware realistic sensor data based on actual orbital physics, allowing you to validate mission behavior continuously, not only right before launch.
What We Offer
Hosted Hardware-in-the-Loop
We host your board into our testing infrastructure and simplify the testing process on your end.
Orbital Emulation
Realistic I2C/SPI/CAN data generation for various sensors (IMUs, magnetometers, star trackers).
Automated Scenarios
Script complex satellite operational modes and run them on every code change.
Fault Injection
Simulate sensor failures, power dips, and bit-flips to test system resilience.
Results Visualization
Clear Pass/Fail status and logs, providing metrics through the whole development cycle.
From Desk to Orbit in 5 Steps
You provide a CubeSat prototype
TestNest hosts it in a controlled environment
Physical sensors are replaced with realistic orbital emulation
Automated mission scenarios run continuously against your software
Receive detailed logs, power analysis, and pass/fail reports
Test continuously — from development to launch.
Who is this for?
If you build satellites and rely on embedded software, TestNest is for you.
