Description

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 modeled and corrected for, yielding the ± 20 mm position solution required by so many industries.

Parked at the front and then wandered around to the back of the building looking for the CORS.
After grabbing the required photo we ducked back through the building to the van as it had started raining.

A quick find after checking out the local virtual cache. I couldn't work out how to spot the antenna until I went around the back and there is a nice location where you can see it easily. Thanks for hiding this one out here for the locals and travelers to find.

Late this afternoon we located the CORS antenna on St Arnaud - it is not the top of the flag pole. The CORS antenna is shown in the two photos included with this log. the antenna is best seen from the car park at the rear of the municipal building. S36 36.904 E143 15.463 is one good location to see the antenna.
