1 Scope
GB/T 46368-2025 is the Chinese national standard covering the survey-grade antenna - the phase centre and its variation with elevation and azimuth, which is the error that limits millimetre positioning, the multipath rejection, the gain pattern across the BeiDou bands, and the anechoic chamber tests. At 22,500 words, first edition, under the Ministry of Industry and Information Technology. In force from 1 February 2026. Issued on 31 October 2025, it has been in force since 1 February 2026.
This document specifies the performance requirements for measurement antennas of the BeiDou Navigation Satellite System (BDS) and describes the corresponding test methods. This document applies to the design, production, use, and maintenance of BeiDou Navigation Satellite System (BDS) measurement antennas (hereinafter referred to as "measurement antennas"). Testing.

The contents of the following documents, through normative references within the text, constitute essential provisions of this document. Dated citations are not included. For references to documents, only the version corresponding to that date applies to this document; for undated references, the latest version (including all amendments) applies. This document.
GB/T 2423.1 Environmental testing of electronic and electrical products - Part
3.1 Terms and Definitions The terms and definitions defined in
GB/T 9390 and the following terms and definitions apply to this document.
3.1.1 With the antenna phase center as the origin of the coordinate system and the antenna axis as the Z-axis, in a plane passing through the origin and perpendicular to the Z-axis, select a certain direction. The direction is taken as the antenna reference direction, with this direction as the X-axis, and the axis passing through the origin and perpendicular to both the Z-axis and X-axis as the Y-axis. The X, Y, and Z axes form a Right-handed coordinate system.
Note. Antenna coordinates often use spherical coordinates. The angle between the projection of the line connecting any point P on the sphere and the origin O onto the XOY plane and the X-axis is phi. The angle between OP and the Z-axis is the antenna pointing angle theta, and the angle between OP and the XOY plane is the antenna elevation angle. theta and the antenna elevation angle are complementary angles, as shown in Figure 1.
