IGS Orbit & erp ComparisonThese graphics summarize the accuracy* of the results of the rapid, final and predicted products provided by all the IGS Analysis Centres.
Rapid products are available within 21 hours after the last observation is collected.
Final products are available within 11 days after the last observation is collected.
Predicted orbits are a propagation of the IGS rapid solution 2 days ahead.
