In 2015, a new 4.5-m radio dish was installed at New Norcia to replace the satellite acquisition capability previously provided by the station at Perth, which was retired. It is designated NNO-2.

NNO-2 offers a wider field of view than the NNO-1 antenna and can acquire signals from a newly launched spacecraft even when its position is not precisely known.

It can also be used to point the NNO-1 antenna. NNO-2 transmits and receives in X-band and can receive telemetry downloaded in S-band for launcher tracking.
