Why purchase a Hemisphere RTK GPS system from

Bench-Mark Equipment has provided outstanding sales service and support to the Survey Industry in Alberta for fifteen years. We specialize in GNSS RTK Survey systems, and are the Western Canadian distributor for Hemisphere GNSS RTK products. Because we specialize in GNSS RTK, we are experts in ensuring your equipment is fully functional, and provide local service and support for the GNSS equipment we sell. Our priority is your success; when you phone us for technical support, you will speak to a real person, and we will do our best to have you up and running in five minutes or less.

Our RTK GPS sales success is due to the quality of the GPS RTK systems we choose to sell and the high level of personal service we offer. By partnering with a Hemisphere GNSS company from Calgary, we can learn the product from the experts who designed it. This allows us to offer warranty repair in-house at Bench Mark, with all of the Hemisphere S321 RTK GPS receiver components we have in stock. Our deep knowledge of GNSS receiver service repairs allows us to repair any receiver promptly.

Hemisphere GPS – Built surveyor tough

With an Ingress Protection rating of 67, and a magnesium housing designed to withstand a two-meter pole drop, the S321 is built surveyor tough and will perform in the same conditions as the Hemisphere S320. The S321 has excellent UHF range capability between base and rover with Pacific Crest, Satel, and Trimble radio protocols. Cellular data capability to connect to any GPS RTK network as a rover via NTRIP protocol. The Hemisphere S321 comes standard with a Satel 1 watt radio, and a cellular modem compatible with all current cellular networks.

Core GNSS technology

The brand-new Hemisphere S321 is the next evolution in Hemisphere’s RTK GNSS survey receivers. It carries over the fast and repeatable performance of the S320 while adding more performance. The Hemisphere S321 supports all existing and future constellations; the S321 currently uses GPS, GLONASS, Beidou, and Galileo in its RTK solution, while QZSS tracking will be added with firmware upgrades. The Hemisphere S321 has enhanced performance through the Athena RTK engine, and can perform in the harshest of Canadian winters. Incorporating Atlas L-Band corrections enables the Hemisphere S321 GPS RTK receiver to perform as a stand-alone high accuracy receiver, making it perfect for off-shore work or steering applications.

The best RTK GPS prices

The Hemisphere S321 GNSS RTK GPS system is priced extremely competitively. Because the Hemisphere company is based in Calgary, Alberta, and Phoenix, Arizona, Bench-Mark has developed a unique relationship and is able to provide an extremely competitive RTK GPS price and level of support that foreign RTK GPS manufacturers have difficulty matching. Our North American manufacturer support speaks the same language and understands the North American survey market. This combined with our Hemisphere S321 RTK GPS lowest price guarantee, means you will save money on your next RTK GPS purchase.

Free Hemisphere S321 training library

Another reason we have had so much success with our S321 RTK GPS system has been our free Hemisphere S321 Training Library on our website, or on YouTube where we provide over 100 one-minute videos to our customers for free. The S321 Training Library will walk you through each stage of the setup process, saving you many hours.

Specialty applications

As a bonus, the Hemisphere S321 GNSS receivers can be programmed for specialty applications, such as hydrographic and echo-soundings. This is accomplished through the use of the WebUI which allows you to configure the receiver to do whatever you want.

Customers who buy RTK GNSS systems often ask…

How accurate is RTK GNSS?

Modern GNSS RTK systems can provide a relative accuracy of 0.8cm +/- 1ppm horizontal and 1.5cm +/- 1ppm in the vertical. This relative accuracy can be translated into absolute accuracy using Monuments. All of Bench-Marks GNSS RTK systems are capable of this level of accuracy.

RTK GNSS prices

How much does an RTK GPS system cost?
Modern GNSS RTK systems are comparable in price to robotic total stations, while providing a much higher level of productivity. As with robotic total stations, prices will vary depending on the manufacturer. With Bench Mark and Hemisphere, you will be getting the best value for money.

Is GNSS surveying difficult?

GNSS survey is extremely easy with Hemisphere equipment and Carlson SurvCE software. Once the equipment has been set-up, you hold you rover upright and click a button on your data collector. Bench-Mark offers training sessions for any customers who would like familiarization.

How long does an RTK battery last?

The Hemisphere S321 comes with two batteries, each with six hours of battery life. This battery life can be extended through the use of Bench Mark’s external power kit, which provides 16 hours of base operation. So the Hemisphere RTK GPS battery can last between 6 and 16 hours.

What is the range of RTK?

The typical range of an RTK system using its internal radios is around 4 – 6 km in the city with no line of sight. This range can be extended by the use of a 35W radio kit to act as a booster or a repeater. All the systems we sell are tested to this specification to ensure radio performance in the field. has been successful selling RTK GPS systems in The USA and Canada because we offer superior after sales service and technical support year after year.
