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

More info on CORS can be found here: CORS

After spending a week in the cairns area where according to locals “the heat and humidity has arrived a few weeks early” .. it was lovely to walk around Toowoomba in nice mild dry weather.

There are two CORS at this location, Toowoomba East (TOOW) and West (TOO1). I tried to access these a while ago on a Sunday but the gates and fences prevented me getting anywhere near them. Today is Tuesday and the front security gates (Tor Street) were open so in I went. A second security gate with a welcome sign was past then through some car parking areas to the left of the buildings. Behind the last building are the two CORS. Images taken and out the way I came. Now it’s time to catch up with a geo-buddy out from Ireland. Thanks for the cache Smile

This Trig took a bit of daring do , but I managed it in the end. I would love to know the story behind two pedestals so close. TFTT Geocaching Australia. Clan Cerberus

The way our GPS wanted us to access this one wasn't an option so we had a read of previous logs and tackled the access ourselves.
It was a bit of a maze to manoeuvre our way through the complex but we eventually got there. Didn't like to leave the van there too long, we may have got away with it and been able to walk right to it if we had been in a normal car though. So we took our photo from a distance with Mr Beetle standing between the 2 markers. Pretty sure the CORS is the one on the right of the photo [or on MR Beetle's left].
Thanks.

#GA3570 - 09:05; Day 4 of a long planned mission to South East Queensland with Sol de lune and after a couple of days in and around Nanango and the wider South Burnett area, it was time to head back towards Brisbane, then home later on Tuesday. This was the first GCA stop for the morning after collecting a few GC caches on the way south. Managed to make our way through the carparks towards GZ and grabbed a couple of snaps of the CORS.

Sol de lune

Day 4 of our 5 day caching run around south east Queensland with LuckyL10n and we stopped for this after leaving Nanango and heading to Brisbane. We found our way through the car park to the back of the buildings and soon had the CORs in view. Didn't venture too close and grabbed the required photo from the safety of the car park.

Thanks for another CORs....

In Toowoomba today to attend a GIFF event and finish off the Toowoomba map of my unfound caches. Knew where to go for this one. When you enter the CSIRO Complex off Torr Street Toowoomba the first thing you see is a sign that directs all visitors to the office. You see other signs as you drive up the long driveway to the back car park. Signs like "Government vehicles past this point only". Up to you as to how you want to go. Parked right up the back and a short walk later on well looked after grass was able to take the photo. You can see the Two CORS markers from the car park. Non one challenged me whilst I was there. only saw two people in the car park and no where else. TFTC GCA. Clan Minotaur

It has taken us some time to work through all the photos we took whilst on our major excursion to get to Brisbane (for a family wedding) via Echuca, Griffith, Cobar, Bourke and Stanthorpe. It was a great trip, one which we will remember for a long time because of the very different landscape types that we went through, the unique characters of each of the towns visited, the wildlife (we hadn't seen very large flocks of emu roaming before)and the different community activities and tourist features.

As we headed from Stanthorpe to Brisbane we stopped at Toowoomba and located the CORS antenna in an open grassed area at the rear of the buildings. In fact we located two very similar antennas, about 2m apart. Only one of these is listed on the SmartNet Aus site. We are not sure if one is yet to be listed or if one is redundant. We could not find any information of wither of the antenna which would distinguish them. Two photos have been added to the Gallery, one of each of the two antenna with Mrs y'stassie standing next to the concrete pillar with the antenna mounted on top. We arrived during business hours and the area was easily accessible and we were able to drive to the rear of the buildings and park close to the CORS. We saw gates on Tor Street and these may be closed after hours limiting access. Thanks Geocaching Australia for the cache.
