Jason-3 satellite was successfully launched on January 17, 2016, and was put on its nominal orbit on February 12, 2016. Jason-3 was flying in formation with Jason-2 only 1 minute 20 seconds, and was about 560 km from Jason-2. Jason-2 was moved to its new interleaved orbit on September 1, 2016. Two orbits were parallel to increase the spatial coverage of satellite observations. The objectives of this paper are to assess Jason-3 data quality and to estimate the altimetry system performance includes validation of Jason-3 data availability and data quality monitoring of Jason-3 and radiometer parameters. The objectives focused on comprehensive comparison of the parameters of the Jason-2 and Jason-3, accurately evaluated the consistency of the two altimeter parameters using the opportunity that the missions were on the same ground track during the formation flight phase, analyzed the ability and stability of the Jason-3 from the perspective of global data, verified Jason-3 data accuracy by self-crossover analysis and dual crossover analysis with Jason-2. From the results presented here, it is demonstrated that the Jason-3 mission fulfils the requirements of high precision altimetry. It allows continuing the observation of the sea surface height variations at the same or higher accuracy as Jason-1, Jason-2 and T/P. In addition, significant wave height quality of Jason-3 data is significantly better than the Jason-2.
