Cumulative solution

Cumulative solution

Since the IDS contribution to the realization of the ITRF2014, the IDS Combination Center (CC) routinely (every three months) computes a DORIS position and velocity cumulative solution from the latest IDS combined series. The cumulative solution provides the usual/classical estimates: station positions and velocities at a mean epoch.

All the details on the elaboration of the IDS cumulative solution can be found in Moreaux et al. (2016).
