In this contribution, the in-house (processed) GOCE products including precise orbit and Earth’s gravity field are compared to the official ESA products. The comparison is drawn on orbit product as well as gravity field level. To ensure comparability, gravity field models from both orbits are estimated in an identical fashion, which is particularly true for the stochastical model. We find that the in-house processed orbit is piecewise rather smooth, but contains jumps like discontinuities in the calculated geometrical point-wise positions. This leads to a degradation of the gravity field solution about by a factor of two in terms of degree variances when compared to the solution from the official orbit product.
