Topcon Hiper Lite NTRIP capable?

At my old office we had a Hiper Lite that had RTCM 2.3 and 3.0, but I think the 3.0 was upgraded/updated later at no cost. One of the limits of a Hiperlite is that Topcon put a base to rover range limit of (IIRC) 1.5 miles on the standard HiperLites, but you can have that range limit removed, for a price ... but you may not have to.

As I understand it, you can use the VRS style of network RTK with a standard HiperLite (since you will set the virtual base point near your site, and therefore "trick" the unit into believing your base is less than 1.5 miles away). If you have the range limit removed (which I think was a $1000 upgrade via an OAF file) then you can use the MAC style of network RTK.

Do you own a Hiper Lite, or are you thinking about buying one? There is a free program called PCCDU.exe that will list the options the Hipers have on/off. If you are buying one, I'd highly recommend having the seller send you the options list, because Hiperlites can vary significantly with their features.

We have a base and rover unit and are just exploring getting set up to use our equipment on the ORGN maintained by ODOT.

Just doing a little homework/recon.

Thanks for the reply. We have pccdu so I will dig a little deeper with that.

The Hiper Lite does support RTCM 3 via NTRIP. Be aware that most Hiper Lite receivers came with a software range limitation that prevents single baseline solutions over 1.5 or 2.5 miles, depending on which version of the Hiper Lite you have. There is a cost to remove the range limitation. Additionally, a firmware update might be required to enable RTCM 3

Thank you. I will check with our vendor.

I could never get my older Hiper Lites do not work on a VRS. Something to do with a hardware limitation.

We have those units, and they work with VRS and RCTM3.0

But...we almost never use them, the GR3's outperform them by a significant degree, in my experience, and we are regularly asking for an upgrade to the GR5.

Since ORGN is a MAC style RTN, that distance limit might be an issue, there will be no VRS next to you to fake it into thinking your baseline is short, I don't know this for sure, BUT makes some sense unless you are close to a actual CORS in the network it might not work with those units.

Anyone ever get this to work? I played around w/it today, but could not get it to work. I used TRU to look up what I had, and I have the dist. limitations on, but the bow-tie surveyor (who was doing an awesome job helping me) said I might want to look into an OAF that opens up my ports as I only have port C listed for corrections on my unit. I've looked on the net for anything about this file and I find nothing. Has anyone gone this route, and been able to successfully "trick" the unit into thinking the baseline is very short? Thanks!

Bringing this back to the surface here, just recently acquired some Topcon Hiper Pro's and was wondering what steps to take to make the rover a network rover, or if it's even possible w/the HIper Pro.

Hi, just wondering if you ever figured this out. Topcon offers zero legacy support for these instruments now, and I'm wondering if anyone every figured out how the OAF's work/are written.

Thanks
