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.

To log a find on the Geocaching Australia website, you will need to include a picture of the CORS, along with your GPS and/or yourself. You are encouraged to leave a description of your journey in your log to help others in finding the CORS.

Logs

Early in 2021 I received an invite from GoosenEgg and Stainless Steel Rat to join them on a caching trip to the Mega in South Australia. As planning got underway some caches with high Favorite points, very old caches, and the On Your Bike Series were listed as "must-dos"
The trip ended up being 10 days of solid and very enjoyable caching with quite a few highlights. The find count for the trip was around the 950 mark when all GCA, Adventure Lab, and GC caches are included. The high point for finds was a day of 335 finds in the one day, which would have been more, but a sudden storm put the end to caching for the day. No one was interested in getting out of the car to find a cache in a downpour in the dark Smile
We were lucky enough to find Gawler Fort Knox, Dustin's Cache, and my favorite for the trip Barossa High (From 21st of January 2001 with the original log book still in place) all in the one day.
Unfortunately, the caching around the mega was beset by bad weather and the day we had put aside for Mount Gambier was scrapped due to a covid case in Mount Gambier on the previous day, so we avoided the area. We all enjoyed the Fishing series and just managed to get the remaining of these before the light failed for the day.
In the end I managed to completed my D/T grid for the first (and possibly the second time) which was my aim for the year, although some of the D/T combinations were not really achievable in Tasmania without a 3 day overnight bush walk.

The agricultural industry seems to have a higher percentage of CORS receivers than non-agricultural.
Another one ticked off the list.
