PARAMETERS OF FEDERAL GOVERNMENT SYSTEMS IN THE 902-928 MHz BAND INTRODUCTION The information provided describes the technical characteristics and deployment information of major Federal Government systems. In order to minimize interference between Federal systems and prospective non-government users, technical characteristics are being made available so that equipment can be designed to reduce susceptibility to interference. The technical parameters that are provided are typical for current equipment. OVERVIEW Currently, there are 18 Federal Agencies along with non-Government entities with authorized frequency assignments in the 902-928 MHz band. Information on the band usage is based on the frequency assignments in the Government Master File (GMF) as of October 1998. A summary of the total number of frequency assignments per agency and operating frequency range is shown below in Table 1-1. It should be pointed out, however, that the number of assignments does not necessarily equal the number of equipments in the subject band. Government Agencies use of an assignment is usually associated with numerous equipment. Government Agencies with less than 15 assignments are grouped into the "other" category. The Department of Defense (DoD) has the most assignments in the band among the Federal Agencies. The DoD primary use of this band is for radiolocation systems. The radiolocation systems employed by the military include: high power long range air search/tracking radars for air defense aboard ships, low power devices such as those for tactical and non-tactical intrusion detection at military facilities, and various tracking and telemetry radar systems to support drone, aircraft, and missile flight testings. The tracking, control and telemetry systems are noted for their wide emission bandwidth (15-17 MHz), low antenna gain (2-6 dBi) and transmit power of 150 or 250 Watts. Other military operations in this band include Government fixed and mobile radio services, including low power radio control operations, are permitted in this band on a secondary basis. Government mobile communications applications by several Government Agencies include hand held transceivers, video surveillance for law enforcement missions, transmission of infrared scanner imagery during overflights of disaster areas, and high power packet radio systems. These mobile systems have emission bandwidth ranges of 100 kHz to 15 MHz, antenna gain of 0 to 6 dBi, and transmit power of 0.01 to 250 Watts. The Government mobile systems include land and aeronautical mobile systems mostly concentrated at military facilities for short range communication to support range instrumentation control operations; point-to-point microwave communication and telecommand networks, video surveillance for law enforcement; and tracking, control, and telemetry particularly at test ranges. The operational point-to-point systems in this band operate with a highly directive antenna (22-27 dBi gain) and emission bandwidth of less than 1 MHz. The transmitting power of the majority of the systems is below 10 Watts. The DoD also uses this band for experimental purposes. The experiments conducted vary from drone, aircraft or missile flight testings, testing and evaluating ship electronic systems or electronic support measure systems, including electronic intelligence emitter location systems and antenna and radar testings. The power used by these experimental systems ranges from 0.0125 W to 300 kW with a range of bandwidths between 2kHz and 20 MHz. The other Federal Government Agencies use of this band is predominantly for fixed systems used for law enforcement operations, specifically systems involving video/voice surveillance. Most of the video surveillance systems used in this band have a emission bandwidth of 6 MHz or more, with typical power of 1 to 10 Watts. The geographic area of operation for these systems is nationwide. Other fixed operations in this band include control at electric-power stations for transmission and management, and point-to-point microwave or TV links for monitoring unmanned ports-of-entry along borders. National Aeronautics and Space Administration (NASA) uses this band to gather critical scientific data that pertains to ozone levels in the stratosphere from remotely piloted vehicles operating at 10 Watts of power, an emission bandwidth of 1 MHz, antenna gain of 0 to 7 dBi and at altitudes up to 85,000 feet. This type of operation is nationwide. NASA, using telemetered data from its ER-2 system, supports different organizations that include the United States Department of Agriculture (USDA) for forest service and fire research programs, Federal Emergency Management Agency (FEMA) for their federal earthquake programs, California Forestry Department for forest fire remote sensing imagery and other institutions (i.e. Red Cross) involved in disaster assessments. Data is telemetered on a 3.5 MHz bandwidth and a power output of 40 Watts. TABLE 1-1 NUMBER OF FREQUENCY ASSIGNMENTS FOR GOVERNMENT AGENCIES IN THE 902-928 MHz BAND Govt. Agency/ Non-Govt.

AN/SPS-49 AIR SEARCH RADAR System Description The Navy AN/SPS-49 high power air search two-dimensional (2D) radar is installed on a variety of ships including all aircraft carriers and at several shore stations. The newer AN/SPS-49A(V)1 is in production and is installed on some ships. Other variants of this radar run from (V)1 through (V)8. The older system variants consists of the (V)1, (V)2, (V)3, (V)4, and (V)6. The newer variants consists of the (V)5, (V)7, and (V)8, which are the automatic detect and track (ADT) equipped radars designed to work with the modern weapon systems such as AEGIS. Operating Characteristics AN/SPS-49 radars have system operating characteristics shown in Table 1-2. Table 1-3 provides the operating frequencies and channels for the (V)1, A(V)1 variant and (V)5 variant of AN/SPS-49 radars. The AN/SPS-49 radar operates on 48 discrete channels between 850 and 942 MHz. The channels (and frequencies) are grouped into three subbands. Each of the AN/SPS-49 variants can operate in the agile mode, and for all variants agility is limited to any one of the three subbands. TABLE 1-2 AN/SPS-49 Operating Characteristics Peak Power Frequency Range 360 kW Typical 280 kW Specified 850-942 MHz (48 Channels) Pulse Width Pulse Repetition Frequency Antenna Gain Sensitivity Antenna Polarization Horizontal Scan Rate Maximum Coverage Range Bandwidth 125 and 2 s [(V)1]; 125, 65, and 2 s [(V)5];32 s [A(V)1] 270 and 285 Hz [(V)1] 213.3-275.6 Hz [long range (V)5] + 12 lower values in Extended Range Mode 326.95-490.56 Hz [anti-chaff (V)5] 859.1-1175.8 Hz [A(V)1] 383.9-574.22 Hz [short range(V)5] 28.5 dB -112 dBm (2 s pulse) horizontal 6 and 12 rpm 550 nmi [(V)1 in Extended Range Mode] 256 nmi [(V)5, A(V)1] 0.4 MHz NOTE: (V)1 refers to (V)1 variant, which includes (V)1, (V)2, (V)3, (V)4, and (V)6.

Generally, AN/SPS-49 emissions are directed seaward to reduce interference to shore locations. However, during Fleet exercises in littoral waters (typically conducted outside of 25 nm from the coasts), the AN/SPS-49 emitters may be briefly closer to the coasts (i.e. launching and/or recovering aircraft). Based on past operational experience, an interference protection zone of 30 nm inland from coastal areas has been found sufficient for sharing with other services and is suggested to reduce potential interference in the areas described below. It should also be noted, that although the Navy has a significant presence in Southern California, Hawaii, and Puerto Rico, the areas described below (#'s 3, 4, & 5), terrain shielding should generally mitigate any potential interference from the subject radar. 1. The area extending 30 nautical miles (nm) inland from the Atlantic Ocean between Wilmington, North Carolina (NC) and Lewes, Delaware (DE) to facilitate Atlantic Fleet exercises. This includes land based AN/SPS-49 radar units at Wallops Island, Virginia (VA), Eastville, VA, Dam Neck, VA, Cherry Point and Onslow Bay NC. Additional intermittent use may occur at the following locations: Naval Air Warfare Center (NAWC) at Patuxent River, Maryland (MD) and facilities at Greenville, South Carolina (SC), Jacksonville, Florida (FL), and St. Petersburg, FL. 2. The area extending 30 nm inland from the Gulf of Mexico between the Louisiana (LA) - Mississippi (MS) state border and Panama City, FL, to support Gulf of Mexico exercises. The area includes Gulfport and Biloxi, MS, and Pensacola and Eglin AFB, FL. 3. Southern California (SOCAL) operations support Pacific Fleet exercises in the Pacific Ocean Naval test areas between Vandenberg Air Force Base (AFB), California (CA) and Point Mugu Naval Air Station (NAS), CA. Additionally, Pacific Fleet exercises occur in Naval Operation Areas (OPAREAS) between Newport Beach, CA., and CA - Mexico international border. Also, the area includes Camp Pendleton, CA. These exercises are normally conducted beyond 25 nm from the areas described above which should limit the potential for interference. 4. The coasts of Hawaii may experience sporadic intermittent interference, however, areas near or surrounding the vicinity of Pacific Missile Range Facility (PMRF) located in south-western Kauai may experience higher incidences of interference. 5. The Armed Forces Weapons Test Facility (AFWTF) is a series of zones in the Caribbean Sea that encompasses all of Puerto Rico and the U.S. Virgin Islands. The coasts may experience sporadic intermittent interference. Table 1-4 below, provides radiation restrictions that are currently in effect. These restrictions are voluntarily implemented by the Navy in current Atlantic Fleet / Pacific Fleet Communication Operations Plan (LANTFLT/PACFLT COMMOPLAN) to maintain the RF emissions in the 902-928 MHz band, including spectral roll-off that interferes with cellular phones, while operating in US&P Littoral waters. TABLE 1-4 AN/SPS-49 Radiation Restrictions LOCATION DISTANCE FROM LAND (nmi) AUTHORIZED CHANNEL Western CONUS ó 200 In-port 29 - 40 none Eastern Pacific (east of the International Date Line including Alaska) ó 200 29 - 40 Hawaiian Islands 25 - 200 ó25 31 - 39 none Eastern CONUS ó 200 28 - 40 Puerto Rico Op Area ó 200 28 - 38 THE GULF RANGE DRONE CONTROL SYSTEM (GRDCS) System Description The GRDCS is a multilateration-based radiolocation system used on the Gulf Range, centered on Tyndall AFB, FL, for three-dimensional positional determination of mobile airborne and ground mission participants. The system operates on a center frequency of 915 MHz, and utilizes multiple measurement sites along the Gulf Coast and in the air. A master computer determines the stations that will be utilized for measurement during each 100 millisecond interrogation cycle, the identity of each participant to be measured, and the delays to be used by each participant relative to the master station sync before responding back to the central site with the range measurement. Hence, using time-of-arrival recording, multiple range-only measurements are made and transmitted to a central computer for determination of time-space-position information, with each position correlated to a unique identification of the participant. Operational Characteristics Each participant location, whether fixed or mobile, consists of an integrated receiver/transmitter/microprocessor (hereinafter referred to as transponders), antenna system, and power supply. These participants can be grouped into three output power categories: normal, medium and low power output. The normal output is 400 watts (ground stations and airborne relays), medium is 200 watts (aerial targets and fighters), and low is 10 watts (missiles). There can be up to 17 active emitters in the air plus four active ground sites during any 100 millisecond measurement cycle. There are ten measurement cycles per second. Ground station antenna heights vary from 50 feet above mean sea level (AMSL) to 500 feet (AMSL). In operation, the transponder may act as the control station, a relay station, a clocking station, or a drone station. The transponder transmitter employs time-division-multiple-access (TDMA) for two to twenty units. It operates spread-spectrum and uses bi-phase-shift keying (BPSK), pulse-coded-modulation with a 10 MHz chip rate on a center frequency of 915 MHz with a bandwidth of ñ10 MHz. (See figure 1 below for spectrum picture.) The emission bandwidth is -1 dB at 14 MHz and -20 dB at 22 MHz. It employs a bandpass filter with a center frequency of 915 MHz providing 3dB at 16 MHz bandwidth and 80 dB at 25 MHz bandwidth. The normal transponder has a mean power output of 400 W coupled with a 1 to 2 dB loss in the coaxial cabling and a 5 dBi, 6 dBi, or 8 dBi gain antenna at the ground station. The majority of the participants utilize vertically polarized, omnidirectional antennas with two ground sites offering a choice between vertical and right-hand circular polarization (RHCP). (All missile packages are RHCP.) Effective Radiated Power (ERP) could be as high as 800 to 1600 Watts depending on the antenna used at a ground station. (Drones, pods, and other aircraft carry antennas with 0 dBi, 1 dBi, or 4 dBi gain.) The transponder contains a single-channel, fixed-tuned/crystal reference superheterodyne receiver employing matched filter detection and is tuned to 915 MHz. It has a received sensitivity of -94 dBm with a signal-to-noise ratio of 16.5dB at the antenna connector (PD = 0.99%). [Spectrum Pattern Picture Available in Hard Copy Form] Sequence of Operation The computer issues a track request via a ground site and imbeds the identities of the participant ground sites, identities of the tracked airborne objects, and the respective delays each participant is to observe before responding in order to deconflict transmissions. Additionally, the computer designates which site is to serve as the master collector of all of the time-of-arrival information before returning the information to the central computer. If any fixed or mobile location is to perform as an active repeater of the instructions (e.g. over-the-horizon), then additional information is embedded to identify the repeater(s), delays, and sites to track the repeaters. Simplistically, the master site asks "where are you" and each identified participant responds with "right here". The instructions received on the uplink delineate how this nebulous response is treated by the TOA collectors, and returned to the computer. In practice, each high-dynamic mobile station is queried 10 times per second, less dynamic stations at a frequency of 5 times per second, and the low dynamic participants at 2.5 times per second. Ancillary Capability The tracking system's ability to transmit measurement criteria to participants is based on a variable message length which lends itself to transmitting additional data to each object, or receiving additional data from the tracked object if a suitable interface is provided. Such information as station health, position refinement from on-board systems, weather or other digital information may be imbedded on downlink responses, all of which may be requested via uplink interrogation. The data throughput capacity of the system is currently 500 kbits/second although the amount of specific data that can be sent is restricted by the amount of instructions that must be sent for range measurements. Operating Areas The system operates from multiple ground sites (up to 15) located along the Gulf Coast from Navarre, Florida to St. Marks, Florida. Airborne systems that are being tracked may fly at any altitude from sea level to above 80,000 feet, and anywhere within the restricted airspace designated as Warning Area 470 (near Tampa, FL) and Warning Area 151 (south of Ft. Walton Beach/Eglin AFB, FL) at slant ranges from Tyndall AFB of approximately 160 miles. More restrictive profiles may be used within the land boundaries of Eglin AFB. HIGH ACCURACY MULTIPLE OBJECT TRACKING SYSTEM (HAMOTS) System Description The HAMOTS consists of a Ranging Operations Control Unit, and a variable quantity of unmanned Ranging Interrogators and Data Relay Units, and Vehicle Transponder Units. The primary purpose of the system is to provide position and tracking data for up to 20 (simultaneously) land and airborne mobile units including missiles, remotely piloted vehicles and manned aircraft. A secondary purpose is to relay test and evaluation data about each of the mobile units back to the Operations Control Unit. Operating Characteristics The HAMOTS system operating characteristics are listed in Table 1-5 below. The system functions by having the Ranging Interrogators and/or Data Relay Units interrogate the various mobile transponders upon command from the Ranging Operations Control Unit. The transponders in turn provides position information and test and evaluation data back to the Ranging Operations Control Unit via the Ranging Interrogators and/or Data Relay Units.

The Air Force has indicated that this does not preclude HAMOTS operations at other locations throughout the United States & Possessions (US&P). UHF WIND PROFILING RADARS System Description Vertically directed Doppler radars, known as wind profilers, can measure the wind speed of crosswind as a function of altitude in a clear atmosphere, where overlying wind streams have substantially different velocities. The wind profiler detects scattering from the turbulent media in the clear air. Clear echoes are quite weak, so that high-power, large-aperture radars are required for their detection. The general shape of frequency spectral for clear-air echoes is a complex function of wind speed. For example, meteorologists need wind information with a very high temporal and spatial resolution, mainly in the lower atmosphere. The requirements are for continuous data acquisition, between the ground and 5 km, with a desirable resolution sometimes as low as 30 meters. Measurements will usually be made in populated areas. Wind profiler radars play important role in experimental atmospheric research. Their ability to measure wind with a high temporal and spatial resolution makes them very well suited for the experimental verification of models, for boundary layer research and for investigation of processes that are important for understanding the atmosphere, including climate evolution. The primary uses of wind profilers in this band are; short-term weather forecasting, air pollution monitoring, wind field analyses and forecasts of toxic plumes trajectories resulting from chemical or nuclear incidents, severe weather warnings for aviation, meteorological observations, airport operations and public protection. Operating Characteristics The operating characteristics listed below in Table 1-6 are typical for wind profilers operating in the 902-928 MHz band.

Other Government Agencies may operate in urban areas throughout the U.S. __________________________________________________________________ SUMMARY The prospective bidder should be aware that the auction of Location and Monitoring Service (LMS) licenses does not change the allocation status of Federal Government operations.
