Ranging measurements and data communication in the radio band have been extensively used in space-based applications, for example in GNSS or GRACE. The increasing demand in high-bandwidth communication and precision ranging will make optical systems ideal for these applications. Experiments in Apollo missions have long ago demonstrated precision ranging measurement and the inter-spacecraft laser link between the NFIRE and the TerraSAR-X recently showed the viability of high-speed optical communication. Our investigations are focused on laser ranging and data communication for the Laser Interferometer Space Antenna (LISA) mission. We present the LISA baseline design and the progress of our experimental demonstration in laboratory.
