PT2_ASSIETTE_SUP_S

Grade PT2 easements concern easements for the protection of radio transmission and reception centres against obstacles
They are established pursuant to Articles L. 54 to L.56-1 of the Postal and Electronic Communications Code in order to protect radio centres from physical obstacles which may hinder the spread of waves.

Two schemes should be distinguished:
— easements established for the benefit of radio centres concerning national defence or public security (Articles L.54 to L.56 of the Postal and Electronic Communications Code);
— easements established for the benefit of radio centres owned by private operators (Article L.56-1 of the Postal and Electronic Communications Code). However, in the absence of a decree implementing Article L.62-1 of the Postal and Electronic Communications Code, operators of electronic communications networks open to the public cannot benefit from radio easements to date.

A plan for the establishment of easements approved by decree sets out the areas that are subject to easement.
Four types of zone can be created:
— primary clearance zones and/or secondary clearance zones around each radio station transmitting or receiving radio waves using directional aerials, as well as around radio laboratories and research centres;
— special clearance zones between two centres providing a radio wave link exceeding 30 megahertz (i.e. with a wavelength of less than 10 metres);
— areas of clearance around radio-tracking stations or radionavigation stations of transmission or reception.

The consequence of servitude is:
— the obligation, in all these areas, for owners to carry out, if necessary, the removal or modification of buildings constituting buildings by nature pursuant to Articles 518 and 519 of the Civil Code. In the absence of an amicable agreement, the administration may expropriate these properties;
— the prohibition, in all these areas, of the creation of fixed or mobile obstacles, the highest part of which exceeds the ratings fixed by the easement order without the authorisation of the minister who operates or controls the centre;
— the prohibition, in the primary zone of release:
* an aeronautical safety station or radiogoniometric centre, to create or retain any fixed or mobile metalwork, bodies of water or liquids of any kind that may interfere with the operation of that facility or station;
* an aeronautical safety station, to create or maintain artificial excavations that may interfere with the operation of that station.
* the prohibition, in the special clearance zone, of creating structures or obstacles siuted above a straight line 10 metres below that joining the emission and receiving airplanes, but the height limitation imposed on a construction may not be less than 25 metres.

PT2级地役权，指为保护无线电发射与接收中心免受障碍物干扰而设立的地役权。此类地役权依据《邮政与电子通信法典》第L.54条至第L.56-1条设立，旨在保护无线电中心免受可能阻碍电波传播的实体障碍物影响。

需区分两类地役权：
— 为国防或公共安全领域无线电中心设立的地役权（依据《邮政与电子通信法典》第L.54条至第L.56条）；
— 为私营运营商所有的无线电中心设立的地役权（依据《邮政与电子通信法典》第L.56-1条）。但截至目前，由于尚未出台针对《邮政与电子通信法典》第L.62-1条的实施政令，向公众开放的电子通信网络运营商仍无法享受无线电地役权相关权益。

经政令批准的地役权设立方案，明确了受地役权约束的区域范围。可设立四类区域：
— 围绕使用定向天线发射或接收无线电波的各无线电电台，以及无线电实验室与研究中心设立的一级净空区和/或二级净空区；
— 为超30兆赫兹（即波长小于10米）的无线电波链路连接的两个中心之间设立的特殊净空区；
— 无线电跟踪站或发射/接收型无线电导航站周边的净空区域。

地役权的约束效力如下：
— 在所有上述区域内，土地所有权人需根据《民法典》第518条与第519条的规定，在必要时拆除或改造依性质属于建筑物的构筑物。若无法达成友好协议，行政机关可对该类不动产进行征收；
— 在所有上述区域内，未经负责运营或管控该中心的部长批准，禁止建造或设置固定或移动障碍物，且障碍物最高点不得超过地役权指令中规定的限值；
— 在一级净空区内的禁止性规定：
* 对于航空安全站或无线电测向中心，禁止建造或留存任何可能干扰该设施或站点运行的固定/移动金属构件、各类水体或液态物质；
* 对于航空安全站，禁止建造或留存可能干扰该站点运行的人工开挖基坑；
* 在特殊净空区内，禁止建造或设置位于连接发射与接收航空器的直线下方10米处的水平线以上的构筑物或障碍物，但对建筑物设定的高度限制不得低于25米。

本数据集介绍了PT2级地役权的地表范围，即一级、二级、特殊净空区及各类净空区域。
