An air navigation service provider (ANSP) is a public or a private legal entity providing Air Navigation Services.^[1] It manages air traffic on behalf of a company, region or country. Depending on the specific mandate, an ANSP provides one or more of the following services to airspace users:

• Air traffic management (ATM)
• Communication navigation and surveillance systems (CNS)
• Meteorological service for air navigation (MET)
• Search and rescue (SAR)
• Aeronautical information services/aeronautical information management (AIS/AIM).

These services are provided to air traffic during all phases of operations (approach, aerodrome and en-route).

Air navigation service providers are either government departments, state-owned companies, or privatised organisations. The majority of the world's Air Navigation Service Providers are members of the Civil Air Navigation Services Organisation located at Amsterdam Airport Schiphol.
