Cal OES Auxiliary Communications Service

The ACS mission is to serve the state of California in support of any possible need relative to communications in an emergency. This means far more than being activated in sporadic emergencies. It includes day-to-day involvement in an emergency preparedness capacity; ACS members act as Emergency Communications Reserves to support the State in providing reliable, point-to-point voice, data and satellite communications anytime, anywhere.
For the state of California, the ACS unit of the Governor’s Office of Emergency Services (Cal OES) provides support for any possible communications need. ACS members possess a variety of professional skills, including administrative, technical, and operational, for emergency tactical, administrative, and logistical communications between the state and its agencies, its Regions, county and city governments, and neighboring state governments.
Specific mission assignments include on-going assistance to counties and cities in developing Emergency Communications units in their respective jurisdictions, coordination with other state agency ACS units, such as those in CalTrans, Cal FIRE, the Department of Fish and Wildlife, and in support of the State Emergency Operations Centers in Sacramento and Los Alamitos.
State ACS, a Radio Amateur Civil Emergency Service (RACES) unit for the state of California, encourages participation and cooperation with (and between) other Emergency Communications (EMCOMM) units statewide, including (but not limited to) City and County RACES units, the Amateur Radio Emergency Service (ARES), The Military Auxiliary Radio System and the American Red Cross.
ACS is actively recruiting volunteers with an interest in public service and a background in emergency communications. While many of our members are Amateur Radio operators, an Amateur Radio license is not required to become a member of the ACS Team. Join us!
