Anyone running one of these as a network rover, opinions?
Is price too good to be true or are the big players just charging way too much?
I recently purchased one to use as an RTK base, transmitting corrections over cellular. It works fine using TCP protocol using an R10 as a rover (Trimble access), so far I have not been able to get NTrip to work in that scenario, although for this situation (RTK base) it really doesn't need NTrip.?ÿ
To use it as a rover I would need a compatible data collector, which I don't have. But, I am considering recommending it as a rover to someone who just needs simple RTK functionality. I need to look at what the data collector creates before I can recommend that because I will be reviewing their data and I need to be able to perform adjustments on the stored RTK vectors. As long as it stores ECEF components and covariance info, then I should be able to use it in my workflow. Mark Silver has been extremely helpful and just an hour or two ago sent me some sample files which I still need to look at but which appear to contain the needed information.?ÿ

Hi John,
Could you please tell us the results when you run your Igage iG8 as a network rover? I'm also interested in that.
Cheers,
Nimal
We'd be running it as network on the NY NYSNet NTRIP with SurvCE, am too interested in your results.
I have recently purchased a network rover and been extremely pleased in the performance.?ÿ I perform quite a lot of rural work under substantial canopy and decided to purchase a base fill-out kit in order to have a base rover pair.?ÿ I have been using RTK GPS off and on since 1998, full time for the last nine years.?ÿ This is the best base rover pair that I have ever used.?ÿ Yesterday afternoon I staked nine points, for four points I was locked onto 22 satellites, for three points I was locked onto 23 satellites and for one point I was locked onto 24 satellites.?ÿ This allows us to perform our work with great confidence and accuracy!

How do you start it as a base without a data collector??ÿ I need a base to go with my R10, maybe 10% of the time.
You can start them as a UHF base from the front panel with a 'Read GPS' coordinate. ("Mode: UHF Base: (...configure radio settings): OK")
You can set them to automatically do a 'Read GPS' and if the current location is with a set distance (say 40 feet) of a previous base position they will 're-use' the previous location. If it is a new position, they will automatically initialize with the new position (Just turn them on.)
You can configure them to known geodetic position via the Wi-Fi interface.
You can configure them to a known geodetic position using a free Android or iOS app (GNSS Tools) via Bluetooth (say from your phone.)
An effective method if you only have one rover on a job is to set the base at a random location (away from the control point you want to use), then initialize the base with a 'Read GPS' position, then do a single point local coordinate (Geo or Grid BOB) on the now free control point.
They are configured to automatically record static observation data so you can always back out an OPUS based position later if needed.
OK, so using the phone WiFi hotspot I could start a base with the correct coordinate using an Android app??ÿ What if I'm in?ÿ phone dead spot, that's where I'd need the base (no VRS).
?ÿCan an G3 be used as a RTK base?
I'll talk with you about it next time I see you, probably Las Vegas couple of weeks from now.
You don't need cell coverage to be able to connect into the unit via wifi. It shows up as an available wifi access point. You would only need cell coverage at both ends (with a static IP) if you want to configure from afar, out of wifi range.?ÿ
Actually, I prefer to use my laptop to start/stop the base receiver rather than my cell phone.Same procedure, just wifi connect. Connecting using a smartphone gives you a more limited menu.?ÿ
But, as Mark said you can start/stop from the front panel of the iG8, one thing that I like about it that my R10 does not have.?ÿ?ÿ
Hi Leon, I will be there! Looking forward to all the trouble that Las Vegas can provide.
Cell service is not required. The iG8 head will be a 'Access Point' so you connect your smartphone to the head with Wi-Fi (password is 12345678), then login (default: admin, password) and navigate to 'Receiver Configuration', 'Reference Station Settings', select 'Manual Base', enter the Lat, Lon and the Reference Height in meters. (Or you can push a button to do a 'Read GPS'). Actually if you want to do 'Read GPS' there is a button selection on the front panel that does it directly.
That is about it. The radios support 'Satel', 'TT', 'PacCrest 4-FSK', 'Transparent' at 9600 / 4800 baud. You can transmit RTCM3.2 (MSM) corrections. It should work. I can stop by someday if you want to try it out.
I don't know if we will be allowed outside in Vegas, although I am thinking that we might enjoy hanging out poolside in the afternoon.?ÿ

Mark,
Found this on the website:
iG3s has Bluetooth and works as an RTK Base.
I need something to replace my 4700's and TSC2's.?ÿ A couple iG3s may work if I can use one with my R10 as a base when needed.?ÿ The VRS is great where I can use it.?ÿ I'm still a bit reluctant to use the VRS in my area where I need as good a vertical as I can get with GPS.?ÿ Not sure the VRS is up to that here.
