Engineering confirmation before ordering
- Specifications are supplier-declared, not independent test certificates. Confirm the current revision, connector, mounting drawing and receiver compatibility before ordering. Phase center error is not a guarantee of positioning accuracy; request a calibration report or ANTEX file if your project requires one.
- BeiDou-focused does not mean BeiDou-only: the supplier table also lists GPS L1, GLONASS G1 and Galileo E1. Confirm this selected-band configuration; do not assume GPS L2/L5 or BeiDou B2 support.
- No IP rating is specified in this source. Do not assume sealed outdoor suitability; confirm the installation and environmental requirements.
