    dct:description "GAMIT processes raw GNSS phase and pseudorange observations, employing a double-difference approach, which minimizes satellite and receiver clock errors by differencing observations between pairs of receivers and satellites. Using a least-squares adjustment, GAMIT estimates precise station coordinates, satellite orbits, tropospheric delays, and, if necessary, ionospheric parameters. The software incorporates external constraints such as International GNSS Service (IGS) satellite orbits and Earth orientation parameters to improve accuracy. GLOBK is a Kalman filter-based software that takes the loosely constrained solutions from GAMIT and combines them to generate a stable, high-precision reference frame. By filtering out temporal and spatial noise, GLOBK refines coordinate time series, computes long-term station velocities, and models crustal deformation." ;
