The precision of the attitude in the inter-satellite ranging missions likeGRACE is one of the important requirement. It is required not only for themission performance but also for the good quality of the gravity field modelswhich are estimated from the inter-satellite ranging measurements. Here wepresent a comparative study of the analysis of two attitude datasets. One ofthem is the standardSCA1Brelease 2 datasets provided by JPL NASA and another isthe reprocessed attitude computed atTU Graz by combining the angularaccelerations and the standardSCA1Brelease2 datasets. Further, we also presentthe impact of the attitude datasets on the inter-satellite range measurementsby analyzing their residuals. Our analysis reveals the significant improvementin the attitude due to the reprocessed product and reduced value of residualscomputed from the reprocessed attitude.
