Towards development of a consistent orbit series for TOPEX/Poseidon, Jason-1, and Jason-2

The space missions discussed in this paper are the primary platforms used to measure global sea level rise. Data from these missions provides fundamental input to the inter-governmental panel on climate change. Inconsistencies exist between the mission records – UCL’s contribution to the orbit determination of these spacecraft helped directly in bringing the data to a common spatial reference system, thereby reducing anomalous signals in the global sea level rise time series. The work was carried out in collaboration with NASA Goddard Space Flight Centre, one of the principal laboratories responsible for production of sea level models.
