Why and how does the tilt compensation RTK solution works？
As we know, the position measured by the conventional GNSS receiver is not directly at the target point but at the antenna phase center. The receiver is usually mounted on a pole that needs to be levelled with a circular bubble in RTK surveys. The target position is calculated by subtracting the phase center offset (PCO) and the length of the pole. Although the results are automatically calculated by the software, it takes time to level the pole, and there will be human errors affecting accuracy.

Where are the actual measurement coordinates?
When various GNSS receivers receive high-precision data from the Global Navigation Satellite System (GNSS) for centimeter-to-millimeter-level positioning, which point coordinates are the positioning data we actually obtain? The point on the ground that the tip of the pole points to? Bottom point of receiver? Or the center point of the antenna? This article will briefly describe where the coordinates really located.

RTCM 3.1 Transformation Messages 1021-1027 Decoder in Tersus Nuwa
As we all know, RTCM messages are used for sending differential GNSS correction data to a GNSS receiver as a rover from a source like a base receiver or CORS Service. And the users of GNSS services normally present their results in the coordinates of regional or local horizontal and vertical datum systems, so the coordinate transformations are necessary.
