New Norcia Station (also known as NNO) is an ESTRACK Earth station in Australia for communication with spacecraft after launch, in low Earth orbit, in geostationary orbit and in deep space. It is located Script error: No such module "convert". south of the town of New Norcia, Western Australia.[1] It was the first ESA deep space ground station,[2] followed by Cebreros Station and Malargüe Station.
New Norcia Station was one of the stations providing communications, tracking and data download from the Rosetta spacecraft.[3] It supports the BepiColombo mission.[1]
History
Construction began in April 2000 and lasted until the end of the first half of 2002. Installation of electronics and communication equipment followed. The station was officially opened on 5 March 2003 by the Premier of Western Australia at the time, Geoff Gallop. Total construction cost was €Template:Replace.[2]
In December 2019, ESA announced plans to build a second Script error: No such module "convert". deep space antenna at New Norcia[4] to provide coverage for upcoming ESA missions, including Solar Orbiter, Hera, and Jupiter Icy Moons Explorer. This was completed in late 2025. The antenna Script error: No such module "Unsubst".Script error: No such module "Check for unknown parameters".
Since June 2019, operational support and maintenance of the station has been the responsibility of CSIRO.
NNO-1
The station operates a Script error: No such module "convert". dish designated NNO-1[5] capable of two-way transmission in both S- and X-bands using 2 and 20-kilowatt transmitters, as well as cryogenic low noise amplifiers for downlink. The antenna weighs over Script error: No such module "convert". and is Script error: No such module "convert". tall. Future upgrade plans include adding a Ka-band station to support international missions.[1]
NNO-2
A Script error: No such module "convert". dish designated NNO-2 was inaugurated on 11 February 2016.[6] NNO-2 acts as an acquisition aid for the Script error: No such module "convert". dish for fast-moving satellites and launch vehicles during their launch and early orbit stage.
The NNO-2 mount is capable of tracking at 20 degrees per second in azimuth and 10 degrees per second in elevation.
The Script error: No such module "convert". dish has a half-power beam width of 1.9 degrees at S-band and 0.5 degrees at X-band and can be used to communicate with spacecraft up to Script error: No such module "convert". in altitude. To help in signal acquisition when the spacecraft position is too uncertain, the Script error: No such module "convert". dish has a Script error: No such module "convert". dish piggy-backed onto it, with a half-power beam width of 3.5 degrees at X-band. There is no S-band capability on the Script error: No such module "convert". dish.
NNO-2 may also be operated independently of NNO-1, as it commonly does during support activities for launches of Ariane 6 and Vega rockets from the Guiana Space Centre.
NNO-3
Construction of the NNO-3 antenna at New Norcia was completed in late 2025. The new antenna is built to the same mechanical specification as NNO-1, utilising a Script error: No such module "convert". main reflector on a mount capable of 1 degree-per-second tracking in both azimuth and elevation, by a consortium of companies. The antenna supports X-, K- and Ka-bands uplink and downlink, and has provision for a future 100Script error: No such module "String".kW class X-uplink.
The antenna is in the final fit-out phase, with operations scheduled to begin in January 2026.
Biomass calibration transponder
A 435Script error: No such module "String".MHz (also called P-band) transponder supports the Biomass spacecraft. This Script error: No such module "convert". antenna performs calibration of the spacecraft during its mission to map Earth's bio-matter.[7]
The antenna makes use of a phased array of patch antennas, rather than the more usual parabolic reflector used for higher frequencies. It is housed within a small radome, which protects the antenna from weather, to ensure calibration passes can be performed regardless of wind speed.
Launcher tracking
New Norcia station is routinely involved in tracking rocket launches from the Guiana Space Centre, including Ariane 6 and Vega launch vehicles, utilising the NNO-2 antenna, and occasionally NNO-1 for longer supports where the launcher ascends to higher orbits. During these supports New Norcia relays telemetry from the upper stage of the launcher back to Kourou.
