Make collision avoidance an economics problem.
Cadence is the Collision Avoidance Design Environment for Cost Estimation. It models the operational, fuel, and mission-impact cost of every response to a conjunction warning, so operators, mission designers, and regulators decide with evidence rather than instinct.
More than 30,000 catalogued objects orbit Earth, and operators receive tens of thousands of conjunction data messages every year. The overwhelming majority require no action. The handful that do can demand fuel-burning manoeuvres that shorten missions and absorb real money.
Existing tools tell you how many conjunctions to expect. None tell you what responding to them will cost. That gap is where operators, mission designers, and regulators lose money and defensibility, because a conjunction rate only becomes a number once you account for the parameters that actually drive the bill.
What Cadence models together
- Probability-of-collision threshold
- False-alarm rate
- Staffing model
- Ground-station network
- Propulsion efficiency
- Decision-authority chain
- Data-provider quality
- Debris-mitigation ruleset
The hard problem is everything in between: the warning where the right answer is genuinely unclear, where action and inaction both carry cost, and where the decision happens in hours rather than days. Cadence is built for that decision.
What Cadence does
Cost modelling
Quantify the full cost of every response: propellant, mission downtime, ground-segment time, and the downstream effects across the fleet.
Comparative analysis
See every option side by side, from minor manoeuvre to no action, with the trade-offs made explicit rather than assumed.
Multi-framework compliance
Check each decision against ESA, US, and ISO debris-mitigation rulesets and the Zero Debris Charter, so your response is defensible by design.
Audit trail
Every decision is documented with the inputs that produced it, ready for internal review or regulator scrutiny.
How Cadence fits
Cadence sits above your existing stack, translating its outputs into the cost and compliance decisions your team actually has to make. It replaces nothing.
Not a data provider
Cadence ingests the conjunction data messages you already receive from Space-Track, EUSST, or commercial providers.
Not a flight dynamics tool
It works alongside your manoeuvre-planning software, not in place of it.
Not a filing system
It produces the cost and compliance evidence you carry into your own review and regulatory submissions.
Who it's for
Mission designers
Phase 0/A/B teams estimating lifecycle collision-avoidance cost across candidate orbits, propulsion choices, and mission durations, before the design is locked.
Spacecraft operators
Operations teams planning manoeuvres against real ground-segment, staffing, and coordination constraints.
Regulators & procurement
Agencies and buyers evaluating operator submissions against debris-mitigation frameworks and the Zero Debris Charter.
Why now
Low Earth orbit is more congested every year. New constellations launch, existing fleets expand, and the rate of conjunction warnings climbs with them. Operators feel this directly. The conjunction inbox keeps filling, and the cost of mishandling it compounds across the fleet.
Regulators are responding. The FCC, ESA, and national space agencies have all moved toward stricter debris-mitigation guidance, and the Zero Debris Charter is raising the bar again. Operators increasingly need to demonstrate that their conjunction response decisions are defensible.
The economics of orbital operations are tightening. Mission lifetimes matter more than ever, propellant is a finite resource, and the difference between a defensible manoeuvre and an unnecessary one shows up directly in the unit economics of every satellite.
How it works
01
Connect
Cadence ingests conjunction data messages in the formats published by your tracking providers.
02
Analyse
Cadence models the full cost of each response option using your operational constraints.
03
Decide
Your team makes the call with quantified evidence, and the decision is logged.
Decision view
Conjunction event, response options
Option A minor manoeuvre
Option B extended manoeuvre
Option C no action
Built with European institutions
Cadence's cost-estimation methodology underpins a research prototype shortlisted for an ESA EXPRO+ activity, and its commercial platform is being hardened for institutional deployment through Triops's incubation at ESA BIC Estonia. Everything runs on EU infrastructure, with data residency in the EU by default.
