The main objective of the Sentinel-3 mission is to measure sea surface topography; sea and land surface temperatures; and ocean and land surface color with high accuracy and reliability to support ocean forecasting systems, environmental, and climate monitoring.
The objective of the Laser Retro-Reflector (LRR) is to permit ground-based laser ranging of the Sentinel-3 satellites. These measurements will be used for calibration of the on-board navigation system and of the Radar Altimeter measurements as well as for the S-3 POD processing. SLR tracking of Sentinel-3A is restricted to a subset of the ILRS network.
The mission's primary instruments are optical instruments (OLCI, SLSTR); and the Altimeter system composed of a SAR radar altimeter, a microwave radiometer, and a Precise Orbit Determination (POD) package composed of a GNSS, a DORIS and LRR.
