For spacecraft manufacturers and operators
Spacecraft data teams can build with, before and after launch.
Give a spacecraft’s readings a clear home. Explore what an assumption changes, understand where each value comes from, and carry that meaning into the next conversation.
A small, interactive example. No account needed.
One spacecraft, a shared question
What changes when demand changes?
Configure the spacecraft
A manufacturer sets out components, readings and units. An operator can start with their own spacecraft too.
Explore the readings
A customer considers a payload’s demand alongside the base systems. Synthetic values make the example’s origin explicit.
Test an assumption
Change one demand assumption and see the remaining power budget. Keep the inputs and the calculation in view.
Try the example
A power budget you can follow.
How much power remains for this fictional spacecraft when the payload needs more?
- Available power Synthetic
- 200 W
- Base systems Synthetic
- 80 W
Enter 0–240 watts in steps of 10. Try 100 W, then 140 W.
Remaining power budget
Calculated60 W
200 W − 80 W − 60 W = 60 W
60 W remains in this illustrative budget.
How this example works
Available power minus base systems minus payload demand. The two Synthetic readings are fixed; only your demand assumption changes. A negative result means demand exceeds the example’s available power.
This is a simplified power calculation, not a battery, energy or flight model. It does not account for eclipse, conversion losses or changing generation.
Illustrative only. Changes stay on this page and reset when you leave or reload. No readings are saved or connected to a live spacecraft.
Before and after launch
Keep the meaning with the reading.
A spacecraft is more useful when its components, units and calculation inputs are understandable together. Manufacturers and operators can each create that starting point.
The next step to discuss in a pilot is bringing measured sources into the same context: preserving meaning, units, timestamps and provenance, while clearly distinguishing measured values from Synthetic ones.
This public example does not connect sources, share access or create independent spacecraft copies. A ready-to-import spacecraft package is a direction to explore, not an available SDK.
Discuss a pilot
Start with one useful question.
Bring this example to your conversation with Arctan. Whether you build spacecraft or operate them, start with the same three things:
- The spacecraft and components you want to describe.
- The readings and assumptions behind a decision.
- The people who need to understand the result.
Agree the data, access and next steps together. This page does not submit a request or create a pilot.
A new organisation starts empty. Arctan Demo is available only to its members.
