Description
This CORS can be found in the Huon Municipal Depot and is easily photographed from the road leading to that depot
A trig point (also known as a Trigonometric Station) typically consists of a black disc on top of four metal legs or concrete pillar, resembling a navigation beacon. It is also accompanied by a metal disc, which is located directly below the centre point of the tripod or on top of the pillar itself.
Trig points are generally located at the top of hills or points of prominence in the landscape. Many provide unique views and challenges, with some being difficult to get to.
These points were regarded as valuable to surveyors, providing reference points for measuring distance and direction, and assisting in the creation of maps.
There are, however, a number of trig points which are not beacons.
To log a find on the Geocaching Australia website, you will need to include a picture of the trig point, along with your GPS receiver and (preferably) yourself. Long distance / telephoto type pictures are against the spirit of this cache. You are encouraged to leave a description of your journey in your log to help others in finding the trig point.
The original collection of trig points has been sourced from Geoscience Australia and may contain inaccuracies.
Please respect local laws and regulations when searching for trig points. If you believe that a trig point is located on private property or in a dangerous location, you may archive the cache, by clicking on Log this Cache and place an "Archived" log on the Geocaching Australia website.
If you feel that you can add to the description of this trig point or adjust the difficulty / terrain ratings, please feel free to edit this cache and amend the information suitably. Vandalism of the cache description or other information will result in your account being terminated.
Huonville CORS
The official name of this CORS Station is HOU1 as per SmartNet Australia
Services: Realtime & Rinex
Elevation: 4.234 (Ellipsoidal)
More info on CORS can be found here: CORS
CORS (Continually Operating Reference Stations) collecting geodetic data from GNSS.
A CORS is a Continuously Operating Reference Station. CORS can take the place of a traditional base station used in differential GNSS positing. They can give an instant position to an accuracy of ±20 mm and are used in many industries including Precision Agriculture, Construction, Mining, Surveying and in Scientific Research.
Typically, the maximum distance between a base station and rover GNSS set up is around 10 - 15 km. This is due to the effect of the atmosphere on the GNSS signals as they travel from the satellite to a GNSS receiver.
With the establishment of a network of CORS, the distance between the base and the rover can be extended. The CORS can be spaced around 70 km apart and using at least 3 of these CORS, the atmospheric effects can be modelled and corrected for, yielding the ±20 mm position solution required by so many industries.

Many tftc GA...much appreciated...cheers ST.
After our 4 day hike we came to this part of Tassi just to leave in hast the next day when we were asked to evacuate from the local fires.
Arrived in Hounville after a scenic journey via Plenty Valley Road. Required pic has been added to the gallery.

We started at Cockle Creek this morning and worked our way up from there.
We have been to caves, a point, trigs, quarries, cemeteries and history boards.
My first CORS find.
I got up early and went for a walk to find a Trig point before it got too hot. After that I came down to Huonville to get some more caches that I hadn't already found this was on the list.
I parked near the gat and took the required photos.
Weather:
Overcast, drizzly and cold
Arrived at ground zero and remained outside the Municipal Depot to take the obligatory photographs
One large truck passed by while attempting the find on this cache
All was quiet here otherwise.
Sainted the cache at 1240hrs
Once all the necessaries were completed, backed up and drove home
DISCUSSION:
A Trig Point is a virtual cache which requires a cacher to locate the Trigonometric Station at GZ:
This was done, but is it a TRIGONOMETRIC STATION or just a CORS? Is there a difference, I don't know but the following definition of a TRIG POINT might suggest there is. Maybe, CORS may need a category of their own rather than be lumped in with true Trig Points.
A trig point (also known as a Trigonometric Station) typically consists of a black disc on top of four metal legs or concrete pillar, resembling a navigation beacon. It is also accompanied by a metal disc, which is located directly below the centre point of the tripod or on top of the pillar itself:
This CORS has no resemblance to a TRIG POINT as defined above - no metal disc was visible upon inspection???
Trig points are generally located at the top of hills or points of prominence in the landscape. Many provide unique views and challenges, with some being difficult to get to:
Definitely not on top of a hill, no prominence on the landscape at all.
The view was below average from GZ but the CORS was easily accessed.
These points were regarded as valuable to surveyors, providing reference points for measuring distance and direction, and assisting in the creation of maps:
Not understanding how a CORS works, I have no idea of its value to the surveying world but will take some time to study their purpose and use.

Photo taken as required and a description of my journey is outlined above . Enjoyed the experience.

Fulfilled this requirement by remaining outside the precincts of the Municipal Depot. Located as have others CORS I have been completed; either the side of a building, atop a building or positioned on the ground. Definitely not in a dangerous position
