Regulation
No. 25-1-111
Information Management
RADIO/SATELLITE TRANSMISSION SYSTEMS
AND
FREQUENCY MANAGEMENT POLICY
14 May 2015
1. Purpose. This regulation establishes and implements policy and guidance for the governance
of the U.S. Army Corps of Engineers (USACE) Transmission Systems (i.e. HF/VHF/UHF,
microwave, satellite, etc.) and Frequency Management practices.
2. Applicability. This policy applies to all U.S. Army Corps of Engineers (United States and its
Possessions (US&P)) elements. Sites minimally supported by ACE-IT are still required to abide
by these policies since this regulation is based on DoD policies/ directives and Army regulations
as defined. Systems and/or equipment requiring frequencies to operate must be coordinated with
the Radio Systems Design Branch as described in section 6 (regardless of intended operations in
federal or unlicensed frequency bands). Examples include: HF Single Sideband; VHF/UHF
land mobile radios (LMR); maritime radio systems; Geostationary Operational Environmental
Satellite (GOES) radios; wireless paging systems; frequency-dependent survey equipment; point-
to-point microwave systems, Very Small Aperture Terminal (VSAT) satellite systems and
services. All radio equipment operating primarily in federal bands requires adherence to federal
rules and regulations for military, civil works, and emergency operations missions. Additionally,
all long-haul satellite services (i.e. VSAT) are to be obtained from the Defense Information
Systems Agency (DISA) via ACE-IT Radio Systems Design Branch.
3. Distribution Statement. This document is approved for public release. Distribution is
unlimited.
