Mission Objectives:

The Jason-3 mission is a joint oceanography mission to monitor global ocean circulation, climate change, and sea level rise. The Jason-3 satellite is the follow-on to the TOPEX/POSEIDON, Jason-1, and Jason-2 satellites. Two other instruments, LPT and Carmen-3, will study the radiation environment at the Jason-3 altitude.

Precision orbit determination is a fundamental requirement for achieving the goals of the Jason-3 mission. The SLR data play an important role in two ways: 1) providing strong tracking information to complement GPS and DORIS and 2) providing a unique and unambiguous verification of the absolute radial orbit accuracy.

Mission Instrumentation:

Jason-3 will have the following instrumentation onboard:

  • CNES Poseidon-3 altimeter
  • NASA Advanced Microwave Radiometer (AMR), three-frequency
  • CNES DORIS receiver
  • NASA GPS receiver
  • NASA retroreflector array
  • Time Transfer by Laser Link (T2L2) payload
  • LPT
  • Carmen-3
