The computation process that produces observed properties from its input data.
Input data may be an acquisition or some other computatation.
Each newly computed observed property that this computation can produce is defined as its *capability*.
The list of capabilities is all-inclusive, even though not every computation can engage all capabilities.

<name>UPC-RapidNetwork: Estimation of Differential Code Biases</name>
<description>
The Differential Code Biases (DCBs) of receivers and transmitters are estimated by substracting the individual STEC from the ionospheric
combination of pseudoranges (P2-P1 in GPS after correcting the transmitter and receiver phase center deviations), by considering an
elevation mask (e.g. 20 deg) to avoid the most part of pseudorange multipath and after applying the DCB datum (the mean value of the
transmitter DCBs is taken as zero as reference).
