- An instructional video showing steps to connect an already configured Topcon GNSS to an RTN provider. With the correct State Plane NAD83 datum and geoid.
Used PC installed MAGNET Field 6.1.1 and Topcon Hiper VR. - วิทยาศาสตร์และเทคโนโลยี
I enjoyed watching the video! Please make a video about RTK procedures for maintaining a good connection to an RTN provider. Last week my Topcon GNSS updated its base station 3 times while I attempted a 3-minute session.
Sorry, stability of RTN connection is a result of too many variables (bad WiFi or interference, broadband 3G/4G/5G low/fluctuating signal, Bluetooth unstable, internet issues at ISP, internet issues at reference station location, server lag, autonomous GNSS lock, bird on base station, etc.). So there is no quick solution. Too many variables. Most reliable FIX is with OWN base & rover :). Sorry...
Hello Dicarlo, so I watched the video and I followed all the steps. I’m using the Connecticut Acorns (cors network). I was able to get connected but my precisions are like 5 feet vertical and 11 feet horizontal. And the bar is red and says autonomous. It never gets into RTK fixed. Is there something else I should be doing
Sorry, never used the Connecticut network. "AUTO" means you are autonomous and not receiving (or applying) the network RTK corrections. So, your network connection is unsuccessful. Check or change your mountpoint. And see how it goes. Also, always RESET (factory reset!) if stuff acts strange. Good luck!
@@DiCarloTV ok great I will try it…thank you
DiCarlo love you channel. I have a quick question. I have a HiperV. I have a license for Pocket 3D and I have a demo version of Magnet Field. My question is when do I know to configure my rover to WGS84, NAD83(2011), NAD83 No Trans? I mostly use a cors network but I also have a hiper v base so I do t have the option of setting on a point and using a base rover setup. Thanks
Depends how your CORS network was set up. Sometimes it is one, sometimes the other. The best way is to check a public control point. And use the datum that matches the control point best.
When using your own base & rover setup, the choice of datum matters not.
@@DiCarloTV that’s what i did. I have i binder with my cities control network. So i went to 2 monuments near my house. I first used NAD(96) because that’s what was used when collecting the data back when they did it and i missed the vertical by 4 feet. I then tried the (2011) and i was still getting a 4 foot bust. I switched to no trans and i was miss within a tenth on the vertical. So I’m going to check a bunch of other monuments to see how no trans works. Now lets say i want to do a project around my neighbor and do a survey of my road, curb sidewalk, etc. using the cors network. Should i then use the no trans when surveying since it worked so well with the monuments?
@@littlenel17 You just answered your question. Use the datum that matches your control! Easy! :) If you want to be 4 ft off from your control, use the other datum.
@@DiCarloTV yeah I just went out and started looking through it, some trial and error. But what I couldn’t figure out was. If I’m on a project and I want to go and set a control point, whether it’s a nail, x-cut or whatever is there a way instead of just taking a quick shot on it, can I set on the nail and do like a 3 minute static reading on it. I feel like with the 3 minute static reading it tends to help with accuracy instead of a 1 second topo shot? Thanks
@@littlenel17 Just change the number of readings for your measurement to 180 (from the default for 3 in Precise or 1 in Quick). That is 3 minutes. DONE :)
