Earth stations operating at non-routine power levels must include the certifications as described in Section 25.220(e)(1) of the Commission's rules, 47 C.F.R. §25.220(e)(1) and must identify the specific satellites for which the earth station intends to communicate. Finally, in items E57 and E59 of Schedule B, you list the East and West elevation angles as 0 degrees. Section 25.205 of the Commission's rules, however, indicates that earth station antenna's shall not be normally be authorized for transmission at angles less than 5 degrees measured from the horizontal plane. Accordingly, we dismiss the application as defective.

Also, in response to Questions E56 through E59 on Schedule B, APS listed the minimum antenna elevation angle for the 3.8 meter hub station and for the 0.25 meter remote terminals as 0 degree. Section 25.205 of the Commission's rules, 47 C.F.R. § 25.205, however, states that earth station antennas shall not be authorized for transmission at an angle that is less than 5 degrees measured from the horizontal plane to the direction of the maximum radiation.

Nevertheless, because of the unusually high, non-routine power levels, we require Intelsat to notify, but not coordinate with -all co-primary terrestrial operators, including such operators licensed in the future, prior to each LEOP operation. In addition to these conditions, we impose a number of conditions to provide further protection to lawful operations from harmful interference. Section 25.205 of the Commission's rules prohibits earth stations from transmitting with an angle of elevation between 0° and 5°, except under certain circumstances not relevant here. The purpose of this rule is to protect co-frequency terrestrial operations from harmful interference from earth stations. While Intelsat states it will not transmit below 5° elevation angles, we expressly condition the Nuevo authorization to

  • Released: July 31, 2003 By the Chief, Office of Engineering and Technology: On April 29, 2003, the Commission released its Fourth Memorandum Opinion and Order (Fourth MO&O), FCC03-97, in the above proceeding. The Fourth MO&O has a typographical error in the new paragraph (g) that was adopted in Section 25.146 of our rules. Paragraph (g) incorrectly cross references non-existent Section 25.205 (o) instead of Section 25.208 (o). The discussion in the text of the Fourth MO&O at paragraph 108 clearly indicates that Section 25.208 (o) is the correct section that should be cross referenced in Section 25.146. We thus correct Section 25.146 (g) to read as follows: ``Operational power flux density, space-to-Earth direction, limits. Ninety days prior to the initiation of

In addition, rain attenuation as a function of path length between the satellite and the earth station (greater at lower elevation angles) will degrade the overall signal-to-noise ratio. The Commission`s rules generally require a minimum elevation angle of 5° for transmitting earth stations. 47 C.F.R. § 25.205. See Ex Parte Comments of Tom Brady, Microcom (March 30, 2001). Because of its high latitudes, portions of Alaska cannot be seen from the geostationary satellite arc at higher elevation angles. Although service is offered, many providers make disclaimers regarding its availability at these lower elevation angles. The relationship between elevation angle and service provision is not absolute. Many other

  • for Direct Broadcast Satellite Service, 17 FCC Rcd 11331, 11358, ¶ 55 (2002) (citations omitted). Satellite operators could establish communications links with satellites at angles of less than five degrees, but the Commission generally prohibits earth stations from operating at these very low elevation angles due to the likelihood of interference to terrestrially based communications networks. See 47 C.F.R. § 25.205 (2002). Many other factors, such as terrain obstacles, foliage density or atmospheric attenuation, can influence the provision of service to a given area. This estimate of the number of visible orbital locations is based upon an assumed elevation angle of 30º and assumes compliance with Commission's two-degree orbital spacing policy for FSS.

See 47 C.F.R. § 25.205 which specifies that earth station antennas will not normally be authorized for transmission at angles less than 5o.
