With the Hemisphere S321+ GSM Cell Antenna, you can use your Hemisphere S321+ as a network rover. With most major carriers supported, simply screw in the GSM Cell Antenna and start surveying. There is no need for a costly external base radio setup, everything is contained within a cell network. As long as cell coverage exists you can use the Hemisphere S321+ as a network rover. This includes our own StormCaster Internet RTK. StormCaster works by using a cellular network to broadcast corrections rather than traditional UHF radios. Using this method, you can theoretically survey over an unlimited range. There is no need to be constrained by the limits of your internal radios anymore. Everything is in reach while using StomCaster with the Hemisphere S321+.

Brian and I took the system out on Sunday and we got radio at 10km. I was really surprised. Brian really likes the system. I will have no problem recommending this to people.

Just wanted to thank you for the great support we got from both of you. S321 is working out pretty good. We went out to the site and the equipment performed nicely. We had a SureFix and it stuck throughout the whole survey, and even after dumping it, it picked it up so quickly. It was a beautiful thing…

It works well and I am happy with it. Topcon can be “tricked” by having a good fix then going into a very high multipath area. Hemisphere S321 will recognize the bad solution much faster and dump the fix. Hemisphere is also better at not giving a “bad” fix in an area like woods where there is high blockage and multipath. Topcon will give the fix but as soon as you start to move it will dump the fix. Hemisphere will hold off on giving the fix until it is actually good. There are some physical features that are much better on the s321. Price-point of Hemisphere is also very attractive. Overall I am happy with purchase and would recommend to others.

Just quick note to commend you on the s321 RTK system we just purchased. It works great under tree canopy, it held a SureFIX in thick tree cover and saved me a bunch of time hiking with my total station. The ties I’ve been getting have been extremely good when checking with my total station.

We love the new S321 GPS set that we recently received. I would like a quote on a second full GPS set just like the last one.

I really like the S321. Battery life is great, positioning is very repeatable and I’m liking Carlson SurvCE more and more. I’m very happy with it. Performance in and around trees is excellent.

The unit is working well, no problems at all. Thanks for getting it to us so promptly.

A great unit. Did even better near trees compared to other GNSS Equipment I’ve used in the past. I will definitely recommend it to others.

The guys that are using the S321 are very happy with them. They fix quickly and seem to be very accurate.

Just an update, well Rene it’s the best built GPS I’ve ever used, I’m completely impressed with the design, the radio is way better now, and since the S321 firmware update it’s repeatability and accuracy has been dead on!
Also this Mesa2 works awesome in every aspect daylight, it’s viewability is like nothing else on the market and in wet conditions the screen works flawlessly.

Thanks a ton!! I love the s321 and I like the 15 min aRTK drift option on the 321, it helps us in a lot of situations.
