3.1 Terms and Definitions The terms and definitions defined in

GB/T 46368-2025, as well as the following terms and definitions, apply to this document.

3.1.1 Antenna phase center The center of curvature of the phase surface of the far-field radiation field of the antenna. [Source: GB/T 46368-2025, 3.1.17]

3.1.2 A module that has both positioning and orientation functions.

Note. This module requires two external navigation satellite signal receiving antennas to process the two navigation satellite signals and complete orientation through BeiDou differential positioning.

3.1.3 cold start sensitivity The minimum signal strength required for a directional terminal to capture navigation satellite signals and achieve normal positioning under cold start conditions.

3.1.4 Tracking sensitivity After achieving normal positioning, the directional terminal tracks navigation satellite signals and maintains the minimum signal strength required for normal positioning.

3.1.5 First fix time The time required for a directional terminal to start up and for the positioning result to meet the requirements.

Note. Startup conditions include cold start and warm start.
