I am looking for a comprehensive comparison between the Javad LS and Leica GS16. Any link?
Thank you.
I've never been around or have I seen Leica GS16. I can answer any other questions on Javad though.
The Leica GS 16 has 555 channels, according to their brochure.
The Javad LS has 864.
This is not going to make a significant difference, in light canopy.
But, in heavy canopy, having a D8 Dozer, will overpower a D5 Dozer.
There is more to it than that, but, in the really tough stuff, the sheer muscle of the Javad is going to be hard to beat.
Having run one for around 1-1/2 yrs, and watching it, i cannot imagine anything with less horspower.
This is just by comparing brochures.

If the R10 cannot hang I would bet the ranch that the GS16 would be left in the dust.

Number of channels is more marketing than a noticeable benefit these days unless the manufacturer tells you exactly how they utilize each channel. I have been told that some manufacturers may dedicate multiple channels to a single satellite. So if Javad were to do something of this nature that 864 channel board doesn't sound nearly as good when it may dedicate 4 channels to a single satellite. Just because a board has 864 channels doesn't mean the firmware will allow it to utilize 864 satellites either.
What I evaluate is the signals and constellations utilized by the measurement engine, performance in the environments I typically work, form factor/weight, ruggedness, collector offerings, software and the value of the package compared to the overall price as well as the dealer.
To me, having a GNSS, TS and collector/software from the same manufacturer, their performance and a dealer nearby to support me when needed is much more important than the number of channels my receiver has.
Is the Javad supporting dynDNS internet service?

In my opinion, yes it is extremely important to achieve a complete GPS+TPS workflow solution. Having said that, it is also an absolute consideration on how deep in the forest you can bring in your control points if the situation requires total station to finish the job. How to balance things here is quite tricky.
Johnson is sort of right... however the Javad has 6 engines, and one more, watching things. With all that's going on, and seeing it happen, just as other users have, said.... then maybe it's not hype in that case.
As far as support goes, The support from Javad has been very good.
A phone call, from your cell phone, while working, and getting you working again, is worth more than a trip to a local dealer.

Hello amdomag,
Yes, our portable RTK base stations (which are typically used with the TRIUMPH-LS RTK Rover), the TRIUMPH-2 and TRIUMPH-1M, support dnyDNS. Also, our full range of TCP enabled reference station solutions support dynDNS as well.

Very interesting. I can see my Leica working with Javad here.:smarty:
Thank you, Michael.

Just because a board has 864 channels doesn't mean the firmware will allow it to utilize 864 satellites either.
Some details of the channel usage is explained on TRIUMPH-LS product page:
[INDENT]Some questioned the need for the 216 channels. They now realize the need for 440 channels. We assign multiple channels to each satellite for redundancy and reliability. We use over 100 channels to scan GNSS bands for interference (patent pending). 864 channels is the KEY to reliable performance.
[/INDENT]
Here are the features of the TRIUMPH-LS and its field software, J-Field, that I find to be most revolutionary and innovative as compared to current GNSS systems:
- The TRIUMPH-LS contains everything needed to function as a complete RTK rover in one small, compact, ergonomic and very portable unit: an 864 channel GNSS receiver, a UHF or spread spectrum radio, a GSM modem, a Wi-Fi adapter, two internal cameras, a flashlight, and a bright 800x480 pixel display. Included with the system is a collapsible monopod rover pole which allows the unit to be quickly folded up to fit in a very small space, perfect for carrying the system through the woods or quickly stowing inside a vehicle. The lack of a data collected bracketed to the rover pole increases further increases its portability and the user can carry the system through the woods without having to worry about a data collector bracketed to the rover pole getting caught in brush.
- This system was ergonomically engineered; the head height vertical display allows the user to operate the TRIUMPH-LS while standing in an upright position and looking forward. The user does not need to bend their neck to look down to view the display as is traditionally done with a system having a data collector attached to a rover pole. This feature allows the system to be used without the neck soreness that can plague a user bending their head downward to view a data collector for extended periods of time.
- The field software, J-Field, is included at no extra charge with the system. There is no need for an external data collector or software. J-Field is constantly being improved and updates will always be available free of charge with the system. The updates can be downloaded through Wi-Fi and are very simple to install, requiring only a couple button presses to update the system.
- J-Field, features 6 separate parallel RTK engines that all run simultaneously with separate assumptions. This allows for fixes to be obtained quicker than if only a single RTK engine was used. It has an advanced RTK verification system that can be used in difficult RTK environments where there is high multipath and/or tree canopy cover. This process will automatically reset the RTK engines and eliminate points from being collected with bad RTK fixes that often plague other systems in difficult locations.
- With the built in GSM modem, it is very easy to connect to RTN networks. Alternatively, it can also be connected through Wi-Fi using a mobile hotspot.
- J-Field has many customization features that can be used to increase productivity as your knowledge of the system grows. The stake and collect screens have 10 white boxes that are easily customized to display a number of fields which the user may desire.
- Post processing raw data is very simple in J-Field. GNSS raw data files can be configured to be stored for each RTK point automatically. After stopping your local Javad base station, the raw base station data is downloaded into J-Field where it can then easily be uploaded to Javad's post-processing server, DPOS (Data Processing Online Service). Autonomous base station coordinates and all the RTK points collected from the base station session can then be adjusted to a solution obtained from processing the base station data with NGS CORS data.
Base to rover vectors can also be processed with DPOS. This allows the user to compare the RTK coordinates with the post-processed coordinates and then choose the desired coordinate for that point. This feature is very useful when surveying in areas outside of the base station's radio range as points can still be collected and post-processed in these areas.
- It contains a built-in compass and tilt sensors. The built in compass allows for the quick and efficient stake out of points. Forward/back and left/right offset readings relative to the face of the display show precisely where the stake out point is located. This stakeout method allows reduces the time required to stake out a point as compared to using traditional north/south and east/west offsets. The built-in tilt sensors can be used in lieu of having to plumb the rover pole. Taking advantage of the tilt sensors is also a "Lift & Tilt" mode that allows for collection of topo points without having to press any buttons. In this mode, when the TRIUMPH-LS is plumbed a point will automatically start collecting and can be programmed to collect a set number of epochs or to stop collection when the unit is tilted. After the point is collected the user tilts the TRIUMPH-LS and walks to the next point which will be collected when the unit is plumbed again.
- Support is provided free of charge by a PLS team that are only a telephone call away. J-Field allows the display of the TRIUMPH-LS to be mirrored to server through Javad??s Remote Assistance & Monitoring Services (RAMS) where support team members can directly connect to the receiver and take control of it to troubleshot problems and provide support.

I get what you are saying, but simply stating 555 vs 864 channels should be important isn't the case, as it could be that one manufacturer utilizes channels differently. The important part of your statement is the 6 measurement engines and checking the integrity of the positioning, not how many channels the board has available.
Mr Johnson, thank you for your input. You are quite right... the sheer numbers are not as significant, as HOW the numbers are working. Combined with the 6 engines, it is simply ridiculous what I'm doing with the LS. Shot where shots cannot happen.... It will really spoil you. It gets a shot, that is impossible, then another, then it's in what looks like an easy place, and it takes 4 minutes. (It's still GPS, and dependent on good geometry).
Hey, get as modern of a GPS as you can. No need getting less than you can.

Has this site become dedicated to JAVAD sales?
Amdomag,
My take on the number of channels.
Yes we devote more than one channel to each signal. This is a great strategy for multipath detection. When you have more "ears" listening to everything, you can determine which is a direct signal, and which signals are reflections. The strongest signal to the receiver may be the reflection off of a tree trunk. I am glad my receiver can isolate the weaker signal that came directly through the tree canopy. This is one of the main benefits of more channels.
