Topic 18 EMCON/SATVULTopic 18 EMCON/SATVUL
Enabling Objectives18.1 DEFINE Emission Control including the advantages, disadvantages and planning considerations for emitter use.18.2 DEFINE the requirements of the EMCON Bill and EMCON status cards.18.3 DISCUSS shipboard EMCON organization including EMCON Control Center, Intermediate Control Stations, and Equipment Control Stations. 18.4 DEFINE SATVUL to include prediction programs and Charlie elements.
Emission ControlEmission ControlDefinition: Selective control of the use of electromagnetic, acoustic, or other emittersDefinition: Selective control of the use of electromagnetic, acoustic, or other emittersto optimize C2 capabilities while minimizing:to optimize C2 capabilities while minimizing: 1. detection by enemy sensors1. detection by enemy sensors
2. mutual interference among friendly systems2. mutual interference among friendly systems
3. compromise of a MILDEC plan.3. compromise of a MILDEC plan.
Advantages and Disadvantages of Emitter UseAdvantages and Disadvantages of Emitter Use
AdvantagesAdvantages
Can deny the enemy the ability to detect and engage friendly forcesCan deny the enemy the ability to detect and engage friendly forces
Can delay or disrupt the enemy’s preparationsCan delay or disrupt the enemy’s preparations
Restricting radiation reduces friendly EMIRestricting radiation reduces friendly EMI
DisadvantagesDisadvantages
Loss of detection informationLoss of detection information
Reduced readinessReduced readiness

Planning Considerations for Emitter UsePlanning Considerations for Emitter Use
EMISSION CONTROL BillEMISSION CONTROL BillImplements EMCON changes with optimal speed and efficiency
Outlines appropriate shipboard emitter status
Establishes EMCON Control Center
Designates Intermediate Control Stations (ICS) and Equipment Control Stations (ECS)
Designates individual responsibility for each shipboard emitter
Provides procedures for:
Intraship reporting
Verification of emitter status
Monitoring of own ship’s emitter status
