RPC Data

Imperial College is the repository of RPC data. All mission data relevant to RPC are made available to the consortium's members on our server. This includes all telemetry data downloaded from Rosetta, the auxiliary data necessary to plan operations and scientific activities as well as RPC own data products resulting from the elaboration of the measurement data.

The table below describes the physical quantities measured by RPC and the sensors' performance.
