The Hemsiphere S321 GNSS Receiver

The Hemisphere S321 has been Bench-Mark’s best-selling surveying receiver for the past three years. This is the best all around piece of equipment we have to offer here at Bench-Mark. This is the receiver that has all of the features of the highest end GNSS manufacturers at a price that is actually reasonable. There is no need to pilfer your coffers in order to pay for this unit. The S321 is designed to quickly pay itself back, and is designed to last you for years to come. This is the network rover that will keep you ahead of the competition for years to come.

 

Multi Constellation GNSS and Triple Frequency

The S321 is Hemisphere’s multi-GNSS, multi-frequency smart antenna. With the Hemisphere S321 you receive corrections from; GPS, GLONASS, Galileo, BeiDou, and SBAS constellations at no extra charge. There is no need to activate the extra satellite constellations, they all come standard with the Hemisphere S321. To add to this, the S321 is also triple frequency. With a triple frequency receiver you have access to the most powerful GNSS signal yet L5. The L5 signal allows you to get performance otherwise impossible with traditional signals, in canopy positions. The L5 signal is powerful enough to get through tree canopies, allowing you to get shots that you would otherwise not have been able to get.

 

Surveyor Tough

The S321 provides robust performance and high precision in a compact and rugged package. With a surveyor tough aluminum body, the S321 is built to withstand whatever conditions you throw at it. The S321 is built to survive a 2 M pole drop. This is the receiver that is built with accidents in mind, and is built to survive them. The IP67 environmental rating means that Hemisphere’s S321 can withstand whatever conditions you face on site. This is the receiver that is built to last for years to come, and has the technology to compete that long as well.

 

Athena RTK Engine

The S321 receiver is powered by Athena RTK technology. With Athena, S321 provides state-of-the-art RTK performance when receiving corrections from a static base station or network RTK correction system. With multiple connectivity options, the S321 allows for RTK corrections to be received over radio, cell modem, Wi-Fi, Bluetooth, or serial connection. S321 delivers centimeter-level accuracy with virtually instantaneous initialization times and cutting-edge robustness in challenging environments.

 

The S321 also boasts the impressive SureFix technology. With SureFix, you can always be assured that the solution you are seeing is the true solution. While determining a a SureFix solution, the Hemisphere S321 runs two solutions in parrellel on the board level. It is doing the equivalent of recording a fixed solution, and dumping the antenna to determine if the fixed position is consistent. You can be assured that a SureFix solution is correct 99.9 % of the time. This is the data you can rely on every time.

 

The S321 receiver also enables users to work with Atlas. Atlas is Hemisphere’s industry-leading global correction service, which can be added as a subscription to the S321. Atlas delivers world-wide centimeter-level correction data over L-band communication satellites. With Atlas, S321 users are able to experience sub-decimeter positioning performance anywhere on earth, without the need to be near a GNSS or communication infrastructure.

 

Atlas L-band has the following benefits:

  • Positioning accuracy – Competitive positioning accuracies down to 2 cm
    RMS in certain applications.
  • Positioning sustainability – Advanced position quality maintenance in the
    absence of correction signals, using Hemisphere’s patented technology.

Powerful Communication

The S321 features the ability to send and receive corrections over both cell and UHF modems. The powerful 1 W internal Satel radio is one of the best in the industry. With an optimal range of 10 km, you barely have the need for an external base radio. This is the receiver that has the radio power to get every survey done. In fact the S321’s internal Satel radio is the best performing radio on Bench-Mark’s Range Test Baseline. Over 3.5 km with no line of site, the internal radio of the S321 has no issues receiving corrections and calculating a fixed position. Once we step out of the truck, the receiver nearly instantly fixes. Every other receiver we have tested on this baseline, has had some range issues. This is the ultimate internal radio.

 

The internal 4G cell modem also allows you to send and receive corrections over cell. The S321 is one of our favourite receivers to use on our own StormCaster internet RTK service. With StormCaster you can set up a permanent base at the office and as long as you have cell service, survey with unlimited range. With an internal cellular modem, you can run an an unlimited amount of rovers of the same base at multiple different job sites.

 

On top of the above mentioned communication options, the S321 also broadcasts a Wifi signal over which setup and updates can be applied. With the Web-UI you can quickly set up static data, a base and a rover with little to no hassle. This is the receiver that has an option for any kind of way you want to work.

  1. Osama Saadeldin – Bosys Technologies

    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…

  2. David M. Brubacher O.L.S. – Strata Surveys

    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.

  3. Todd Kuntz – City of Saskatoon

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

  4. David Swatzky

    I can tell you everything works flawlessly and we would be in a very tight spot if you hasn’t been able to ship the gear that you did in such short notice! 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.
