Delta-DOR - a new technique for ESA's Deep Space Navigation

When ESA's second deep space antenna became available in late 2005 Cebreros in Spain, the Agency could begin using a powerful new navigation technique particularly important for interplanetary craft: delta-DOR. Delta-DOR contributed to the successful orbit insertion of Venus Express around the planet in April 2006, and it is expected to be a fundamental tool for navigating all of ESA's current and future interplanetary missions.
