Neuraspace
Neuraspace STM & Ops is a European SaaS platform that uses AI and machine learning to screen, classify and resolve satellite conjunctions. It turns raw collision warnings into ranked alerts and ready-to-fly avoidance manoeuvres for satellite operators.
What is Neuraspace?
Neuraspace STM & Ops is the space traffic management module of the Neuraspace platform, a Portuguese software-as-a-service product built to keep satellites from colliding. It sits between the operator and the flood of conjunction data messages that arrive as low Earth orbit fills up. The company frames the problem in operational terms: a team assessing a verified close approach by hand typically needs about eight hours, while a single operator working inside Neuraspace can review a flagged high-risk encounter and pick from a shortlist of suggested manoeuvres in minutes.
The platform ingests conjunction data messages from Space-Track and from operator systems, along with OEM and OPM files, GNSS measurements and space weather. Proprietary machine learning models classify and prioritise each event, then propose collision avoidance manoeuvres shaped by the spacecraft's constraints. Screening returns results in under an hour against the eight hours the company attributes to Space-Track, and the paid tier advertises Neuraspace screening as fast as five minutes. Manoeuvre suggestions can arrive up to five days before a conjunction. An unusual feature is the built-in chat that lets operators from different companies coordinate who moves — the practical problem in any two-satellite encounter.
Alongside public catalogues, Neuraspace feeds the models with its own optical telescopes, the second of which was installed in Chile in December 2024. The product is delivered in two tiers: SYNC, a permanently free coordination layer built on public data, and PRO, a paid tier that adds the AI predictions, automated manoeuvre suggestions, GNSS ingestion, custom integrations and a dedicated account manager.
The company reports monitoring more than 600 satellites for customers including Spire Global, GEOSAT, NanoAvionics, Sidus Space, U-Space and the European Space Agency, with defence work for the Portuguese Air Force and NATO. Universities and agencies such as ESA, GMV, Instituto Superior Técnico, NOVA, Carnegie Mellon, Portugal Space and the University of Coimbra appear as research partners or customers — they are collaborators, not certifications held by Neuraspace.
What it does
- Ingest conjunction data messages from Space-Track and from operator systems, including OEM and OPM files
- Classify and rank every conjunction by risk using machine learning predictions
- Generate collision avoidance manoeuvre options that respect each satellite's constraints and priorities
- Coordinate manoeuvres directly with the other operator through an event-driven chat
- Track satellite position in real time and export ephemerides as TLEs or OEMs
- Trigger conjunction screening on demand, from the interface or through the API
- Push alerts by email, web platform, Microsoft Teams or signed webhooks
When to use Neuraspace / When not to
A quick filter to help you decide if Neuraspace is the right fit.
When to use Neuraspace
- Satellite owners and operators running fleets of anything from five to several hundred spacecraft
- Small flight dynamics teams drowning in conjunction data messages they must triage by hand
- Launch service providers needing precise tracking and screening through early orbit operations
- Defence and governmental organisations monitoring and protecting national space assets
- Space insurers and underwriters who need current collision statistics to price satellite risk
When not to use Neuraspace
- Consumers and hobbyists: this is a professional space operations platform, not a sky-watching app
- Teams that need a mobile or offline tool, since the product ships only as a web application and an API
- Buyers who require a published price list before making contact, as no figure appears anywhere on the site
- Operators wanting automated manoeuvre suggestions on the free tier, which deliberately omits the AI layer
- Organisations needing a signed data processing agreement or product terms up front, as neither is published
How to use Neuraspace
A typical end-to-end flow, from setup to results.
- Open a free SYNC account from the tier page using the "Get free access" link
- Sign in to the platform at app.neuraspace.com
- Register your satellites and set assets, thresholds and manoeuvre preferences
- Connect Space-Track so conjunction data messages flow in automatically

- Run the two-month pilot the company offers to compare speed and accuracy with your existing solution
- Subscribe to PRO to unlock ML predictions, automated manoeuvre suggestions and GNSS ingestion
- Integrate technically through the Platform and Integration APIs, or push OEM and OPM files over FTP
- Automate downstream alerts with signed webhooks, or build on the Python, .NET and TypeScript SDKs and the manoeuvre CLI
Pros & Cons
Pros
- A genuinely free permanent tier, SYNC, rather than a countdown trial
- Unusually complete public technical documentation, roughly ninety pages, readable without an account
- A properly documented API with Swagger, three environments, four official SDKs and a command-line tool
- Screening turnaround advertised at under an hour, and under five minutes on PRO, against eight hours for Space-Track
- Operator-to-operator chat for cross-company manoeuvre coordination, a rare capability in this market
- Proprietary optical telescopes supplementing public catalogues, giving data the free sources do not carry
- A European publisher with named commercial, institutional and defence customers
Cons
- No price is published anywhere: the PRO tier shows only the word "Subscription"
- No terms of service, licence agreement or data processing agreement exists on the site
- The only legal page is a privacy policy that covers the website and explicitly not the platform
- That policy was last updated in June 2021 and still relies on the invalidated EU-U.S. Privacy Shield
- No hosting country or region is disclosed, and the policy allows transfers outside the EEA
- The homepage says the models are fed by customer datasets, yet no document governs or limits that use
- The tier page is not reachable from the site navigation, and the interface is English only
Pricing & Plans
A permanent free plan is available. The SYNC tier is offered at no cost and is presented as free access rather than a time-limited trial. The paid PRO tier is described only as a subscription: no amount, currency or billing period is published on the tier page, the product pages or anywhere else on the site, and no online checkout exists. Pricing must therefore be obtained by contacting Neuraspace, typically through the 30-minute demonstration that precedes the two-month pilot the company proposes.

Data, GDPR & hosting
A consolidated view of how Neuraspace handles your data.
GDPR overview
GDPR compliance is claimed in plain terms: the privacy policy states that personal data is stored "in accordance with the EU General Data Protection Regulation (Regulation (EU) 2016/679)", enumerates six lawful bases and lists the data subject rights of access, erasure, rectification, complaint to a supervisory authority, information, restriction, portability and objection, plus rights over automated decision-making. No data protection officer is named; the single contact is info@neuraspace.com. Two caveats matter. The text was last updated on 15 June 2021 and still relies on the EU-U.S. Privacy Shield, struck down in July 2020. It also defines its cookie rules by reference to the UK Privacy and Electronic Communications (EC Directive) Regulations 2003 and to "English and EU Cookie Law", although the publisher is Portuguese — a template mismatch, not a change of establishment.
Who owns the data?
The published documents do not settle ownership of mission data. Neuraspace's only legal page is a privacy policy whose own definitions limit it to "neuraspace.com and all its subdomains" — the marketing website, not the operational platform. No terms of service, end-user licence or data processing agreement exists: every likely path returns the site's error page. The controller is named as Neuraspace Lda., registered in Portugal under number PT516136658. Nothing published states who owns the ephemerides, conjunction messages and telemetry an operator uploads, nor what Neuraspace may do with them. The policy does reserve the right to transfer user data if all or part of the business is sold.
Reuse rights
For platform data, nothing is published: with no terms of service and no licence, the site never states whether an operator may freely reuse, redistribute or commercially exploit what the tool produces. What is documented is the delivery mechanism — tracking results are returned to the customer as Tracking Data Messages through the Files page and the API, and ephemerides can be downloaded as TLEs or OEMs, which implies practical reuse within the customer's own operations. On the website side, the privacy policy lists uses limited to running the site, personalisation, newsletters, market research and analytics, on six enumerated GDPR legal bases, and names Facebook, Google Analytics and Google Ads as recipients. Read the absence of product terms as an open question, not as permission.
Data retention & training
Hosting summary
Neuraspace discloses no hosting location. Neither the privacy policy, the technical documentation nor any product page names a country, a region or a cloud provider for customer data. The only geographic statement runs the other way: the policy warns that some data may be stored or transferred outside the European Economic Area, and that where such a transfer occurs the company relies on EU-approved standard contractual clauses — alongside a clause requiring third-party processors to adhere to the EU-U.S. Privacy Shield, a framework invalidated in 2020. Stated security measures are databases reached over SSL connections, restricted access, and SHA3-256 hashing of email identifiers in parts of the system that do not need them in clear. One technical indication points towards Europe without amounting to a disclosure: the three authentication tenants documented for the API all sit in Auth0's EU region. Treat hosting jurisdiction as an open question to raise before contracting.
Things to keep in mind
Risks and trade-offs to weigh before adopting Neuraspace.
- The only legal document is a privacy policy that scopes itself to the website: nothing contractual governs the mission data you upload to the platform.
- The homepage states the AI models are fed by datasets from customers and partners, yet no agreement frames that use and no opt-out is documented.
- That privacy policy was last updated in June 2021 and still relies on the EU-U.S. Privacy Shield, invalidated by the Schrems II ruling in July 2020.
- No hosting country or region is disclosed, and the policy expressly allows data to be stored or transferred outside the European Economic Area.
- Automated manoeuvre suggestions can encourage over-reliance: they are decision support for qualified flight dynamics staff, not a substitute for operator judgement on an irreversible burn.
- Published performance figures — 100x faster decisions, 80% less staff time, screening under an hour — are the vendor's own claims and are not independently verified.
- Named partners and customers such as ESA, GMV, Portugal Space and several universities are collaborators or clients, not certifications or approvals held by Neuraspace.
Setup & Integrations
Technical difficulty
Low to start, moderate to integrate. The free SYNC tier is a self-service web sign-up with nothing to install: register your satellites, connect Space-Track and you are reading classified conjunctions. Going further means real engineering — feeding OEM and OPM files through the API or FTP, wiring signed webhooks, and configuring thresholds and manoeuvre rules, which assumes flight dynamics or software staff. Three environments allow testing before production, official Python, .NET and TypeScript SDKs and a manoeuvre CLI reduce the work, and PRO includes a dedicated account manager.

Should you pick Neuraspace?
Neuraspace STM & Ops is one of the more convincing operational tools in its field. The product is real and in service: the company reports monitoring more than 600 satellites for customers that include commercial operators, the European Space Agency and defence organisations, and the technical documentation is public, detailed and unusually generous — a fully specified API, three environments, four SDKs and a command-line tool, all readable without an account. The free SYNC tier is a genuine permanent plan, which means an operator can test the coordination layer and the operator-to-operator chat without a sales conversation or a credit card. For a small flight dynamics team, that alone is worth the hour it takes to sign up.
The weakness is contractual rather than technical. Neuraspace publishes no terms of service, no licence and no data processing agreement; the only legal document on the site is a privacy policy that explicitly scopes itself to the website and not the platform, was last revised in June 2021, and still cites the EU-U.S. Privacy Shield, invalidated in 2020. Nothing published says who owns the ephemerides and conjunction data an operator uploads, where they are hosted, or how long they are kept — while the homepage advertises that the models are fed by datasets from customers. For mission data of any sensitivity, those questions belong in the first procurement conversation.
The absence of published pricing has the same effect: SYNC lets you judge the product, but the cost of the tier that carries the actual intelligence stays behind a demonstration and a two-month pilot. Evaluate the free tier on its merits, then negotiate the contractual terms the site does not yet provide.
