Calculation of the velocity components for continuous GNSS station through applying the algorithm for least squares adjustment.

<p>The calculation of the velocity of a continuous GNSS observation station represents a key input in modern surveying. The act of determining the position of the GNSS stations involves daily which can establish the time series of stations, based on which information can be influenced by phenomena affecting the performance thereof. This article is a description of the algorithm of the least squares adapted and applied to the determination of the velocity components of continuous observation stations. Furthermore, this algorithm is applied for calculating the speed of ETCG station belonging to the Geocentric System for the Americas (SIRGAS).
