Where in Canberra is this survey plate?

Where in the Australian Capital Territory is this benchmark (BM) survey marker plate (general location say within 1 km)?

Who’s into Geocaching, do you know the precise location?

Clues: Space, STS, year 1981 and the number 26   🙂

Survey Plate

Answer:  At the former Orroral Valley Tracking Station operated by NASA.  The benchmark plate is at the base of the former 26 metre radio telescope once use to communicate with the Space Shuttle Columbia. The 26m antenna is now located at the Mount Pleasant Radio Observatory, Tasmania operated by the University of Tasmania.

Of interest to some radio amateurs will be the base of the former WWV antenna and mast

Justin VK7TW was so close.  Here is a photo of the former NASA lunar laser ranging station 1.7 km south-west, at a bearing of 240 degrees from the survey plate, keep guessing.

  1. Would that be Nm C 106 the former Orroral Lunar Laser Ranging Station? There is a connection between the Tracking Station and Tassie as the University of Tasmania ended up with the parabolic tracking dish and reinstalled at Mt Pleasant near Richmond in Southern Tasmania.

    • Hi Justin, it’s not the Nm C 106 Laser Ranging Station which is 1.7 km from this survey marker. The connection to the University of Tasmania is correct, excellent work. You have the answer, almost there, so close!
      FYI – I have updated the post with pics of the former NASA Lunar Laser Ranging station.
