-The transformation to <u>GDA94 is an exception</u> in this because it involves a ten times higher scale parameter compared to the other transformations. Note that hence the resulting height biases for a BNC-transformed GDA94 corrections stream can increase up to about 10 centimeters.
+The transformation to <u>GDA94 is an exception</u> in this because - compared to other transformations - it involves a ten times larger scale parameter. Therefore and in addition to the implemented orbit transformation, clocks are corrected proportional to topocentric distances between a representative mean Australian surface position and GNSS satellite positions. Hence the height bias resulting from the application of a BNC-transformed GDA94 correction stream is also expected to not exceed one centimeter.
