Triumph T-3

A year ago I started working for a Company that used Carlson Survey data collectors and have several non-Javad GPS receivers. I am trying to convince the Owner to purchase a T-3 that I could use with my LS. If this happened I would upgrade to an LS+. Would the rest of the company be able to benefit from the T-3 base using Carlson field software and non-Javad Receivers. Two of the newer recievers are advertised to do 4 constellations.

I would give a qualified "yes". You could try it out now by setting up your Triumph-LS as a base using all four constellations and see if your existing non-Javad rovers work well with the data. If so, I can't think of a reason that they would not work with the Triumph-3. Also, interesting fact, Carlson SurvCE/PC 6.x supports the Triumph-3.

The reason I give a qualified "yes" is because I think that different manufacturers may use different parts of Beidou differently. That's supposition on my part based on some reports of difficulty in some cases of mixing receiver brands with Beidou. But you have the pieces there to test and see if the different receivers will work well together.

Does the T-3 come with internal cell and does it still have to have a static IP to work as a base station? If they wanted, could they use this as an RTN receiver through SurvCE?

You can get the T3 with an internal cell modem and purchase a static IP Verizon sim card from Javad. I haven't personally tried the t3 withh survce but I think the option is there in survey version 6.

Best thing I ever did was ditch SurvCE and go full Javad.

What kind of Range are people getting using only the built in UHF with the T3 as the Base?

This doesn't answer your question but the T3 comes with a rubber duck antenna. You can also order a long-range kit that has a 5/8 wave, 5db gain, hard antenna, and 12' cable. This is the setup I try to push users that use UHF instead of cellular.

Currently I am using the T1-M with its built in UHF that uses that Green 8" stick as an antennae. I get upto around 1200 feet out of it.
In thinking of upgrading to the T3 - I am curious as to what I will get with it. A lot of my setups are in urban-esque environments and another set of legs for the antennae mount is not really ideal for most of my projects.

I have been using the 1-M for a couple years now and best case scenario with 1 watt built in radio is 6,200' in perfect conditions from open ridgetop to open ridgetop. I almost always get at least a couple thousand feet in deep woods, and start getting a little iffy at around 3,000' generally. According to Matt Sibole, with the LS, screwing on an external antenna only marginally helps with the signal reception.
In three days, my new LS+ and T-3 get shipped from San Jose and I opted for the cell upgrade in the base to use TCP when cell service is an option. The LS+ and T-3 use a lot more information that cannot fit on the previous UHF signal and must use a slightly different type that will carry the load, but it is my understanding that the range with the new UHF signal will only reach 80% as far as the old signal. Of course, cell signal length is unlimited as long as there is service.

Perfect description, Tom.

For anyone with the cell coverage, I highly, highly recommend going cellular for base and rover communications.

Shawn,
Would you mind explaining this to me?
It sounds to me that instead of the Radio - Both base and Rover use cellular communication?
Would this do away with the need for a uhf radio - assuming that you are always in an area that has cell coverage? Which is basically everywhere nowadays.

Thank you,

Hi Joe,
Yes, that is correct. You can accomplish this in a couple of ways. You can have an internal cellular modem in the base and rover along with a SIM card. At the base, you need a static IP address. Javad offers Verizon SIM cards with static IP addresses at a cost of $500 per year at 500MB/month which is plenty for Base Rover communications. You only need the static IP at the base. You can also obtain a data plan from several providers with a static IP address. The IP address needs to be IPV4. The data plan could be for a SIM card that is placed in the base or in a mobile hot spot device, such as a Jet Pack. If you are using a hot spot at the base, then the base does not need a cellular modem. It already has WiFi (Triumph-1M, Triumph-2, Triumph-3) which only needs to be configured to connect to your hot spot. At the rover, you only need a basic internet connection. This can be same data plan a person might have for a tablet or similar device. As with the base, you could get a SIM card that can be placed in the LS/LS Plus, or you could use a WiFi hot spot. I use my cell phone at the rover. Regarding the Triumph-LS/LS Plus, there are a couple of things to be aware of:

1. All Triumph-LS/LS Plus receivers have a cellular modem installed.
2. The modem may not be active, unless you paid for the option already.
3. The modem may only be GSM capable. It is now possible to get a dual band modem that supports CDMA and GSM. CDMA is Verizon, GSM is AT&T. If your modem is GSM only, you can send it in for a new modem (costs apply) or just use the WiFi hot spot option.

The Triumph-3 only has a cellular modem installed if it is ordered with one. A cellular modem can be installed in the Triumph-3 after the fact, costs apply. The modem installed in the Triumph-3 is dual band (GSM and CDMA).

I've been very pleased with the effective range of RTK work with the Triumph-LS Plus and Triumph-3 combination. Yesterday I surveyed a five acre tract that was 10 miles from my office. I set up my Triumph-3 at the office and was able to do the survey without incident. Every point collected was under canopy, mixed pine. Last week I did an as-built survey on a four acre tract I surveyed about 4 years ago that is about 8 miles from the office. Initially I surveyed the tract from a DPOS base position. I tied into a boundary monument from 4 years ago as a check from my office base, also determined from DPOS, and my check shot agreed within 0.02' horizontally (I didn't notice vertical difference). So I'm pleased with the range I get from cellular. I would not want to be without UHF, but I feel good about only having a 1-watt UHF internally as a back-up to my cellular communications for my particular circumstance. I have cellular coverage almost everywhere, UHF is just a back up for ocassional instances where I may not have cellular coverage.
