USA Mobile User Objective System (MUOS) in Niscemi, Italy


The Mobile User Objetive System (MUOS) is a modern satellite communications system of the US Navy. It consists of five geostationary satellites and four ground stations, with each of the latter including three swivelling very high frequency satellite dishes with a diameter of 18.4 meters and two Ultra High Frequency (UHF) helical antennas. MUOS will replace the UHF Follow-On (UFO) satellite system currently in operation and it will be used for the capillary coordination of all U.S. military systems deployed around the globe.

Project Details and Actors
Project DetailsThe MUOS Ultra High Frequency (UHF) SATCOM system (300 MHz to 3 GHz frequency range) encompasses four on-orbit satellites, one on-orbit spare and four ground stations placed in Virginia (USA), Hawaii, Australia and Sicily. The first two MUOS satellites were launched in February 2012 and July 2013. The MUOS program, primarily intended for mobile users (e.g. aerial and maritime platforms, drones, ground vehicles, and dismounted soldiers), is still in its development stage and is expected to launch all satellites into orbit by 2015.

The program is expected to provide service through 2025.

The MUOS installation in Niscemi includes three swivelling very high frequency satellite dishes with a diameter of 18.4 meters (1600W) and two UHF helical antennas (105W).

The UHF Follow-On (UFO) satellite system in operation in the NRTF base of Niscemi since 1991 consists in 45 antennas HF and 1 antenna LF with an emission power in the range of 500-2000 kW.
Project Area (in hectares)122
Level of Investment (in USD)11,000,000 USD (Niscemi installation)
Type of PopulationUrban
Potential Affected PopulationNiscemi inhabitants are 27 932, but impacts would be felt in a much more extended area

Environmental ImpactsVisible: Air pollution, Biodiversity loss (wildlife, agro-diversity), Loss of landscape/aesthetic degradation, Deforestation and loss of vegetation cover
Potential: Food insecurity (crop damage), Genetic contamination, Noise pollution, Soil contamination, Reduced ecological / hydrological connectivity, Other Environmental impacts
OtherBees, important for maintaining the biological balance of ecosystems are particularly sensitive to the presence of high electromagnetic fields
Health ImpactsPotential: Accidents, Exposure to unknown or uncertain complex risks (radiation, etc…), Deaths, Other Health impacts
OtherMicrowaves emitted by the parables of the MUOS system could be high dangerous radiation for the surrounding areas. Moreover in the first years of operation should be added radiations emitted by the 46 existing antennas UHF Follow-On (UFO) satellite system which in measurements made by the Regional Environmental Protection Agency (Agenzia regionale per la protezione ambientale, ARPA) exceeded emission limits prescribed by law as demonstrated in the technical study promoted by the Administrative Tribunal of Sicily in 2013.

Given the risk of biological effects on humans, flora and fauna, the study shows the need to conduct an updated and complete research to verify the conformity of the MUOS.
Socio-economic ImpactsVisible: Militarization and increased police presence, Loss of landscape/sense of place
Potential: Loss of livelihood, Loss of traditional knowledge/practices/cultures, Specific impacts on women, Other socio-economic impacts
OtherThe electromagnetic field induced could interfere with neighboring airports (Comiso, Sigonella and Catania) and airplanes flying in the beam of the MUOS parables.

The Niscemi station of the most advanced U.S. military communications system could expose local population to become a military target.

Development of AlternativesNo Muos movement demands the definitive revocation of the authorization for the installation and activation of the MUOS.

They also question the very reason of having US military installation in Sicily and oppose military interventions in North Africa and Middle East which use Sicily as the main navy base.
Do you consider this as a success?Not Sure
Why? Explain briefly.No Muos movement raised the attention of local and national authorities and citizens on important issues as territorial sovereignty and human health. The movement was able to bring into question the legitimacy of the process of authorization and obtained the temporarily revocation of the authorization, mainly for the serious risks to the environment and human health caused by the electromagnetic waves of the MUOS. Presently the project is under construction and all the actions to stop the installation are still in progress.
