GWEN Towers, HAARP & Satellite GPS-EMF Control Grid

"GWEN is a superb system, in combination with cyclotron resonance, for  producing behavioural alterations in the civilian population. The  average strength of the steady geomagnetic field varies from place to  place across the United States. Therefore, if one wished to resonate a  specific ion in living things in a specific locality, one would require  a specific frequency for that location. The spacing of GWEN  transmitters 200 miles apart across the United States would allow such  specific frequencies to be 'tailored' to the geomagnetic-field strength  in each GWEN area."
- Robert O. Becker, M.D., in "Crosscurrents: The Perils of  Electropollution"
"Russian satellites, controlled by advanced computers, can send voices  in one's own language interweaving into natural thoughts to the  population of choice to form diffused artificial thought. The chemistry  and electricity of the human brain can be manipulated by satellite and  even suicide can be induced. Through ferocious anti-humanitarian means,  the extremist groups are fabricated, the troubles and bloody  disturbances are instigated by advanced tele-means via Russian  satellites, in many countries in Asia, Africa, Europe and Latin  America."
Dr Nassim Abd El-Aziz Neweigy, March 21, 1983, Assistant Professor in  the Faculty of Agriculture, Moshtohor Tukh-Kalubia, Egypt, writing in  The Sydney Morning Herald
"Specifically, this agreement establishes the overall policies,  relationships, and responsibilities guiding interagency activities  necessary to establish, operate, and manage the NDGPS as authorized by  Section 346 of Public Law 105-66 of October 27, 1997 (Attachment A)  including for the temporary and permanent transfer of mutually selected  USAF Ground  Wave Emergency Network (GWEN) sites and equipment to USDOT  for use to establish the NDGPS radionavigation service as authorized  under Public Law 105-66, Section 346 (Attachment (C))."

The agreement also  establishes USACE, FRA, FHWA, USCG, and NOAA responsibilities for the  funding, installation, operation, and eventual decommissioning of  Nationwide DGPS sites.
In Presidential Decision Directive (PDD) NSTC-6 of March 28, 1996, the  President designated the Department of Transportation as the "lead  agency for all Federal civil GPS matters." In addition, the President  directed the USDOT to "develop and implement U.S. Government  augmentations to the basic GPS for transportation applications."
In January 1997 the USDOT formed an interagency DGPS Executive Steering  Group and a DGPS Policy and Implementation Team to investigate the  development of a nationwide differential service to comply with  Presidential direction. The findings of the Executive Steering Group  determined that building upon existing infrastructure and resources -  Coast Guard Maritime Differential Global Positioning System (DGPS)  sites and conversion of existing US Air Force Ground Wave Emergency  Network (GWEN) sites - was the most practical method available to  adequately fulfill the PDD and meet the user agency operational and  technical needs.
Section 346 of Public Law 105-66, dated October 27, 1997, (Attachment  A) grants authority to the USDOT to "take receipt of such equipment and  sites of the Ground Wave Emergency Network ... as ... necessary for the  establishment of a nationwide system to be known as the 'Nationwide  Differential Global Positioning System .'"
In November, 1998, the NDGPS MOA was signed, identifying the general  responsibilities of the seven Federal Agencies involved in the planning  and proposed implementation of the NDGPS service.

300 Towers, 300-500 Feet High, Spread Across the United States
The Ground-Wave Emergency Network (GWEN) System
Extract from Matrix III Volume One:
The Ground-Wave Emergency Network (GWEN) is a communications system  that the military is in the process of constructing as we speak. It  operates in the very-low-frequency (VLF) range, with transmissions  between 150 and 175 kHz. This range was selected because its signals  travel by means of waves that have a tendency to hug the ground rather  than by radiating into the atmosphere. This signal drops off sharply  with distance - a single GWEN stations transmits in a 360 circle to a  distance of 250 to 300 miles. The entire GWEN system consists of  approximately 300 such stations spread across the United States, each  with a tower 300-500 feet high. The stations are from 200 to 250 miles  apart, so that a signal can go from coast to coast from one station to  another. When the system is completed around 1993, the entire civilian  population of the United States will be exposed to the GWEN  Transmissions.
APPLICATION OF MILITARY FREQUENCY WEAPONRY :
According to a 1982 Air Force review of biotechnology, ELF has a number  of potential military uses, including "dealing with terrorist groups,  crowd control, controlling breaches of security at military  installations, and antipersonnel techniques in tactical warfare."
"Electromagnetic systems would be used to produce mild to severe  physiological disruption or perceptual distortion or disorientation. They are silent, and counter measures to them may be difficult to  develop."

Each site would consist of a 299 foot tower (presumably to get around  automatic imposition of the National Environmental Policy Act  requirement for an environmental impact statement for any  federally-funded 300 foot tower), a concrete building, and a series of  fences on a 700 foot square site. Underground, a "ground screen" of  copper wire would radiate to 330 feet at regular intervals. Physically  unimpressive, the towers are presented to the public by the Air Force  as radio towers for "emergency communications."
Each tower will cost $1.4 million, the entire system a billion dollars.  Other systems such as AFSATCOM, Milstar, Green Pine, and Giant Talk are  designed to provide nuclear war communications at other electromagnetic  frequencies and with the same or other weapons systems. Because of  GWEN's relatively simplistic technology, the Air Force presumes that  GWEN will be replaced in 15 years by a satellite system.
