ETSI ETSI TR 103 233 V1.1.1 (2016-04) 5 1 Scope The present document provides a characterization of antenna performances for earth stations on mobile platforms. It identifies the technologies and antenna types used in such systems, which may not have the sam

16、e performance characteristics considered when developing the existing ETSI standards for VSATs. Antennas used on mobile platforms are typically smaller and have radiation patterns that may have variable symmetry and/or variable geographic skew angles toward the satellite. These types of antennas are

17、 typically used in low profile antennas or other special applications. Their radiating patterns may show non-conformances with regard to the ETSI off-axis EIRP density mask. The present document proposes a method to cope with this non-conformances issue, called the “non-conformance-area“ (NCA) metho

18、d. The method relies on a geometrical mathematical object, called a NCA, defined as follows: A “non-conformance-area“ (NCA) is an area of preferably simple geometric shape defined on the antenna radiating pattern that identifies the set of directions where the ETSI mask is exceeded, associated with

19、an indicative level of severity in the perspective of a further interference analysis. As far as 3D geometry in space is concerned, the NCA method is an extension of the ETSI TR 102 375 i.6 report that “provides guidelines for determining the parts of the satellite earth station antenna radiation pa

20、tterns concerned by the geostationary satellite orbit protection“. The rationale underlying the NCA method is: 1) As long as there is no victim system in the directions of a NCA, there is no possible harmful interference occurrence for that directions. 2) When a victim system happens to be in the di

21、rections of a NCA, a possible interference event occurs in the scope of a non-conformance to the ETSI mask. This event is called a “hit“. 3) A coarse level of severity is associated by analysis to each “hit“. 4) Statistics are performed about the occurences of “hits“ during operations, providing wit

22、h a comprehensive assessment of the hit occurences issue. The NCA method may support a rationale as suggested by FCC 47 CFR 25.138 (b) i.1 as stated hereafter: “(b) Each applicant for earth station license(s) that proposes levels in excess of those defined in paragraph (a) of this section shall subm

23、it link budget analyses of the operations proposed along with a detailed written explanation of how each uplink and each transmitted satellite carrier density figure is derived. Applicants shall also submit a narrative summary which must indicate whether there are margin shortfalls in any of the cur

24、rent baseline services as a result of the addition of the applicants higher power service, and if so, how the applicant intends to resolve those margin short falls. Applicants shall certify that all potentially affected parties (i.e. those GSO FSS satellite networks that are 2, 4, and 6 apart) ackno

25、wledge and do not object to the use of the applicants higher power densities.“ The NCA method may also support a rationale as suggested by FCC 47 CFR 25.227 (b)(2) i.2.

42、tations ETSI ETSI TR 103 233 V1.1.1 (2016-04) 8 4 General concepts Fore the purpose of the present document, the satcom antenna technologies for Mobile Platforms are partitioned as follows: 1) The radiating panel generates a fixed beam, typically in the boresigth direction of its radiating surface.

43、It is mechanically aimed toward the satellite. For the purpose of the present document, this antenna type is called MS-FA for Mechanically Steered - Fixed Aperture. 2) The radiating panel has an electric beam steering capacity either 1D or 2D (for 1 and 2 Directions) from its boresight. In case of a

44、 partial electric beam steering (a complementary mechanical beam steering is implemented), the antenna type is called HS-VA for Hybrid Steered - Variable Aperture. 3) The radiating panel has an electric beam steering capacity either 1D or 2D (for 1 and 2 Directions). In case of full electric beam st

45、eering (no complementary mechanical beam steering is required), the antenna is called ES-VA for Electric Steered -Variable Aperture. For ease of understanding, each antenna type is matched to a particular antenna technology: 1) Mechanically Steered Fixed Aperture (MS-FA): a rectangular radiating pan

46、el mounted on a mechanical Elevation over Azimuth positioner. The antenna is housed under a “low profile“ radome mounted flat on the platform body (for instance the fuselage of an aircraft). 2) Hybrid Steered Variable Aperture (HS-VA): a MS-FA antenna where the antenna radiating panel performs an el

47、ectric cross-elevation axis. The overall physical shape is kept unchanged with regard to MS-FA type. The antenna is housed the under a “low profile“ radome the same way. 3) Electric Steered Variable Aperture: a thin radiating panel mounted flat on the platforms body (for instance the aircraft fusela

48、ge), and performing a 2D electric beam-steering from its boresight. It is sometimes referred to as a conformal antenna. The rationale linking the antenna types to the antenna technologies is: 1) Only asymmetrical (e.g. “low profile“) antennas are considered in the scope of this study. Hence, the cro

49、ss-elevation axis, if any, is bound to be electric. A mechanical cross-elevation axis rotation has its range limited by the radiating panel bumping into the radome and into its floor. 2) If the elevation axis is mechanical, the antenna type is either MS-FA or HS-VA depending on the existence of one cross-elevation axis or not. 3) If the elevation axis is electric, the antenna type is either MS-FA (if the radiating panel surface is typically inclined from the platform horizontal around 45) or ES-VA (if the radiating panel is mounted flat/hori
