Key issues (1/2)

We had contributions with respect to: • Characteristics of GNSS biases, e.g., receiver dependence

(categorization of receivers, “receiver groups”, “receiver families”, list of factors to be relevant for detected (bias) dependence becomes longer and longer (due to MP mitigation mode and many other factors)

• Treatment of GNSS biases - RTCM-SSR strategy and bias treatment - Presentation of a possible way on (generalized) handling of

GNSS biases as realized at CODE - Comparison of MGEX SINEX_BIAS V0.01 results
