An EMSO is an organisation mandated by any EUROCONTROL Member States to provide air traffic services in their territory, whether this organisation is state-owned or privatised. Member State military organisations are de facto EMSOs.
An industry providing services to an EMSO is considered to be an EMSO for this purpose.
For Non-EUROCONTROL Member State Organisations (NEMSOs), SASS-C may be made available subject to the signature of a license agreement but also upon payment of an acquisition fee of €20,000, then a €5,000 EUR yearly maintenance fee.
Any organisation outside EUROCONTROL Member States and the manufacturing industry whether located inside a Member State or not are considered as NEMSOs.
An EMSO providing services outside EUROCONTROL Member States is considered to be a NEMSO for this purpose.
SASS-C Maintenance And Support (SACMAS) service is only available to EMSOs. Subscription requests should be submitted by completing the online subscription form.
Please consult our examples of EMSO and NEMSO user license agreements. For questions concerning licensing please contact out Licensing Requests team. For other questions please send an e-mail to the SASS-C Management team.
