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.

I had just finished finding a multicache in the cemetery, when I looked over this way and realised I could see the CORS from the cemetery, so grabbed my camera and took the photograph from there. Then off to my motel for the night. TFTC.

What a great way to start my two weeks of ‘Annual leave’. I decided on a Geocaching trip down to Holbrook to find all the lone unfound caches, along the way. I left early in the morning, and found majority of caches on the to-find-list. I ended up in Holbrook by 11am, which I decided on having an early lunch. After lunch, I headed down south for a couple of other caches before starting to head in the home direction. All up, I end the day with 26 finds which was made up with 24 GC and 2 GCA caches. It was a great trip and day out. There were many types of hides, containers, and sizes, which lead to varying difficulties to find. Most were quick finds and all were in good condition. TB visit. A big thanks to the CO for adding this cache to game for the Geocaching community to enjoy. Big Grin
