Hemisphere GNSS

Hemisphere GNSS has built a reputation on providing accurate and reliable GNSS positioning devices for over 20 years. They are renowned for their innovative and affordable positioning antennas and receivers. Having started in the agricultural market with the Outback brand, they have branched out to create the incredibly popular Vector line of marine antennas and the S-series surveying receivers. 

Hemisphere GNSS is based in North America, with headquarters in Scottsdale Airzona, and offices in Calgary Alberta and Winnipeg Manitoba. What this means for you is that support is always in your time zone. There is no need to send your devices across the ocean to get fixed, everything is fixed in North America. For the last 10 years, we have prided ourselves here at Bench-Mark with providing a North American survey solution at an affordable price point. Our partnership with Hemisphere is a big part of that. 

The Hemisphere S320

The Hemisphere S320 was Hemisphere’s first forray into providing a survey based solution, and was one of our best selling receivers of all time. The Hemisphere S320 provides a robust, reliable and accurate solution, that was beloved by countless of our customers. 

The Hemisphere S320 uses Hemisphere’s Athena RTK engine, an older version of the engine found in the newer S321 and S631 recievers. The Athena RTK engine is capable of superior multi-path performance. As the S320 is a 4th generation receiver, it does not have access to the latest signals and constellations but still performs great. The Sure-Track technology inside the receiver improves RTK in congested environments and long-range baseline degradation. 

GPS: L1C/A, L1P, L2P, L2C



Flexible Communication Options

The S320 boasts an internal 1 Watt 400 Mhz radio that can give you up to 3 km of range. The internal radio is capable of broadcasting many of the most common message format types; CMR, CMR+, RTCM 3 and Hemisphere’s own ROX format. 

The S320 also has the ability to use an internal cell modem. The internal cell modem allows you to use the Hemisphere S320 as a network rover, or broadcast corrections using the cell modem. This allows you to work with the solution you want. With solutions like StormCaster you can acheive much further ranges than the traditional base and rover. 

With the S320 you also have the ability to capture static data with an SD card. All you have to do is turn the receiver on and the data is logged to the SD card automatically. 


Used Equipment

All of our used equipment is rigorously tested to ensure that it meets our used equipment standards. Before the instrument is sold, we test to ensure that the instrument specifications are as expected, and any broken parts are replaced or refurbished. Our standard testing regiment includes a range test to ensure the radios of any GNSS receiver are still operating within specifications. Our test course is a 3 km in city range test with no line of sight. This ensures the test is as close to what you experience in the field as possible. For total stations, we ensure that the unit is within expected calibration by shooting multiple points, with both sides of the total station. If work is required, we have an optical expert take a look and adjsut the unit. 

Next we ensure that the instrument has the latest firmware and drivers available. This is to ensure that the unit is working as well as possible when you receive it. In order to repair used equipment, we keep a range of parts for all Hemisphere recievers, and many of the other leading brands. This allows us to repair and refurbish instruments that are otherwise not supported by the manufacturer. Finally, the units are thoroughly cleaned to ensure they look as new as possible.


Unit Condition

This specific unit is in excellent condition. The previous owner treated the instruments very well, and although they show cosmetic scuffs and scratches it is in perfect working condition. The units have been tested on our range course and passed with flying colours.

  1. Brady Lange – PotashCorp

    I’ve now had plenty of time to learn how to effectively use the equipment it seems to be working perfectly.

  2. Kevin – Bullee Consulting

    Next time we buy another RTK System we will not even consider anything else, we love the s320.

  3. Mathieu – Northcan Surveys

    This Hemisphere S320 tracks satellites and holds a fix position better than any GPS I have ever used before.

  4. Bill – JWL Engineering

    Accuracy is amazing, I turn it on and it just works!

  5. Kevin – University of Calgary

    I like it. Works well around trees and buildings…stays fixed longer, and if fix is lost, regained faster once back out in the open.

  6. Patrick Russnak – Lecor Construction

    I use the S320 it every day for the pipeline work it has performed very well, with near-perfect accuracy. I am very happy with the unit.

  7. Adam – SNC-Lavalin Inc.

    I have had no complaints from my 10 survey crews, so I will take that as a good sign.

  8. Tom Carter – Eagle Creek Technical

    So far so good, no problems. Thanks!

  9. Gord Cunningham, Survey Contractor

    This Hemisphere S320 works just fine.

  10. Casey Pennington – Vesecky Engineering & Surveying

    It is all going well.

  11. Dustin – Pinter & Assoc.

    It’s runs good every day!

  12. Roger – County of Vermilion River

    The equipment is working great.

  13. Steve – Madison Resource Solutions

    The s320 equipment has been working very well for me. Any glitches I have experienced have mainly been my finger input problems.

  14. Michael Byrne – Northwest Harris

    The S320s are working great! It’s one of the smarter purchases I’ve made. The accuracy is 2 times better than using my old sokkia 2700is! The company is very happy with the amount of stakeout I complete.

  15. Bill – TJC Engineering

    The system is working well!

  16. Andrew – BMC Services Ltd.

    The system works really nice.

  17. Cam , A.L.S.

    So far so good, it’s been working pretty good. What I really appreciate is your service.

  18. Danny Benson – Timbercraft

    The S320 is working perfectly, as for the Hemisphere GPS I couldn’t be happier. I can’t believe the difference between the old unit I had before and the S320. It has cut my field work time almost in half so easy to setup, very fast RTK lock fixes and I really like the Carlson software.

  19. Alex Campbell – Northcan Surveys

    Everything is working fine.

  20. Eric A. Zabate – Clifton & Assoc. ltd.

    So far so good, it’s working well. Surveying has been easier since I got it.

  21. Duncan Spenst – Water Security Agency, SK

    The system has been working excellent! We are definitely getting more distance from the base with the Pacific Crest external radio. We were out surveying in some rugged terrain a couple weeks ago and were about 8 miles south of the base and we were still able to get a fix solution.

  22. Paul Grimard – Arpenteur-Géomètre

    L’équipe de support technique de Carlson a rapidement trouvé la solution (qui originait de la configuration de Windows). Ce petit mot pour vous réitérer mon entière satisfaction de faire affaires avec vous et Carlson, tant au point de vue de la qualité des produits qu’à celui des services; je vous recommande à mes collaborateurs !

  23. Edward Salmon – Edward Salmon Surveys, Fort McMurray, AB

    The performance of the S320 receivers is outstanding. The fix comes very fast and holds it in areas that I didn’t get before.

  24. Tammy Smith – OGL Engineering

    Great customer service!
