NYSNet w/ Hiper Lite+ & Carlson SurvCE

I have used a Leica 1200 OK a few years ago, but can't help with your exact hardware. Have you used NYSNet with any brand of equipment before? It is a Leica Spider Net, not sure what Topcon is looking for, BUT probably some flavor of RTCM?

Are you in WI, trying to hook to this? In Spider, the owner can set up parameters that can limit you from hooking up, need to be inside the network possibly, or close to it. I know NYSNet wouldn't work on the ME/NH border when I tried it in the past, even though I could connect to the servers it wouldn't give a float or fixed solution.

Just some rambling thoughts, BUT might give you some ideas to consider.

Shelby,

I am inside the network helping a friend out on a project. I can login no problem and am receiving a data stream, but I will check with the DOT Monday to make sure nothing is "locked" on the account. Although spidernet, NTRIP is required for connection.

I have not used the newtwork before and didn't attempt to connect while back home due to the distance, I assumed it would not work.

Thanks for your input, it is very much appreciated.

I use the NYSRTN often. There are several possible problems here.

1) The Hiper Lite has 1.5 miles limiter from the base, and the Hiper Lite+ is 2.5 miles. You need to purchase OAF go beyond this distance from any base station in RTK. This is NOT a VRS system it is an RTN, which means your receiver will read the actual distance to nearest base station. NYSRTN have base stations about 40 miles apart. So most likely you will be more than 1.5 miles from the base.

2) When using a network correction you also need RTCM, TCP and Ethernet enabled in your OAF.

3) Now even if you have all of this working, I have seen poor SV geometry and waited more than 30 minutes to go from Float to Fix. NYSRTN only uses NAVSTAR SV's, no GLONASS.

Thanks Shelby and Lee,

I have everything correct in my connection and have narrowed it down to either firmware and/or distance to base. We are going to check it within 2.5 miles of a station and see what gives.

Will report back.

Thanks again.

Matt

Be interested to hear the results. It works, so sounds like the Topcon distance limit is a likely good guess as to the problem.

Distance from base was the issue I had earlier this week. Inside of 2.5 miles from any one cors site, no problem was had...

Thanks again to Shelby and Lee,

Matt

Glad it worked out, thanks for letting us know.

I just used the Topcon Receiver Utility (TRU) to view the Options on my Hiper Pro rover. Most relevant to this thread was the option named "RTK Distance, km". In my case, this option was listed as "No restrictions" for both Current and Purchased columns, and "Disabled" in the Leased column. I take this to mean that the distance limitations that you mentioned in your post, Lee, would not be applicable in my case. Does that sound right to you?

Matt,

You may wan to consider upgrading your SurvCE at least to SurvCE V2.62, or pay the $150 to Carlson SW for the newer SurvCE V3+, All sorts of new Features and Driver Updates in the new SurvCE V3+

When you connect to the NYSDOT-NYSNET, (when I still worked for LGS, I installed all the NYSDOT-NYSNet Reference Stations.) your RTK Rover will download the NTRIP Source Table, depending upon the NTRIP Mount point you select, your RTK Rover may need, or NOT need to send in the RTK Rover's NMEA-GGA position.

In newer TN VRS Now RTK Networks, the VRS Now REQUIRES the RTK Rover constantly send in the RTK Rover's NMEA-GGA position atleast every 30-seconds, most VRS Now RTK Networks want the RTK Rover's NMEA-GGA position to be sent into the the VRS Now Server every 10-seconds.

The newest Carlson SW SurvCE v3 now supports the RTK Rover to configure (Data Collector Internal),and send the RTK Rover's NMEA-GGA position at any common rate, (10-seconds), to the VRS Now Server, that right there is worth the $150 SurvCE Upgrade, IMHO. There's a new Sheriff in the Hemisphere (HGNSS)...

Thanks for posting on this. I'll gladly upgrade to SurvCE 3.x.

I'm not exactly sure whether my data collector will handle the upgrade to SurvCE 3.x. I have an Allegro CX, with 128MB Ram and 512 MB internal storage. It has bluetooth capability and has two 9 pin serial connectors as well. USB connection is normally available through charging cradle, but I don't have the cradle, rather just use 12VDC power connector at top of unit. Data collector runs CE.NET 4.20.

Looks like my Allegro CX meets the minimum requirements.

Big Al,

Give the Carlson SW Support team a call, or send them an email message, I'm sure they can confirm if your Allegro CX can handle the SurvCE v3 upgrade.
