Frequently Asked Questions

Hemisphere S631: The Performance Champion

The Hemisphere S631 works best for surveyors and civil engineers who need accuracy on the centimetre level but don’t want to pay a Trimble tax. Surveyors value its reliability, affordability, and performance under canopy. For good reason, it is our best-selling GNSS RTK receiver. 

Hemisphere S631 Key Features

Here is why it has become that popular:

  • Multi-constellation tracking and 5 Frequency Tracking across GPS, GLONASS, Galileo and BeiDou
  • Athena RTK engine with SureFix Technology
  • Multi-Communication Technology; 400 MHz and 900 MHz Radio, Cell Modem, WebUI and Bluetooth
  • 3rd Generation IMU Tilt Technology
  • Dual hot-swappable batteries for all-day operation

The Hemisphere S631 stands out because it truly works everywhere. Whether you work near buildings in urban zones, in heavily treed rural job sites, or on busy and congested construction sites, the S631 can acquire fixed solutions. Paired with the IMU tilt sensor, you can spend less time waiting on your receiver and more time surveying.

How It Beats the Competition

  • Price-to-performance is unmatched
  • Full tilt support with no yearly subscription
  • Openness: Works with FieldGenius and other open systems

It adapts well on large-scale subdivision surveys, boundary surveys, construction sites and environmental monitoring in remote locations.

Trimble R980: Premium Performance, Premium Price

If you have heavy integration needs and a large budget, then the Trimble R980 will cover your needs. Trimble has led the industry for years and for a long time has been the industry standard in RTK. Their latest receiver the R980 is the newest in their long line of RTK receivers. Integrating into the existing Trimble ecosystem, it is a solid 7th generation RTK receiver. However, if you are already on the R12 platform there isn’t much reason to upgrade. The R980 is simply an R12 with an internal 900 MHz radio. 

Trimble R980: Key Features

Here is what you are paying for:

  • High-end IMU with enhanced tilt compensation
  • Trimble ProPoint GNSS engine
  • Full integration with Trimble Access workflows
  • Cellular and radio correction options

In the field Trimble R980 possesses fast fix times and holds signal well in difficult environments. The main benefit is the tight integration with Trimble’s software and survey ecosystem. That means that it should most likely become your choice if you are already into Trimble hardware and software.

What Is Outstanding About Trimble R980

The set of benefits is impressive, however, many Canadian customers find themselves locked into expensive service agreements or unable to use other software. Otherwise, they face compatibility issues. Here is the breakdown in this light:

  • Cost. Expect to pay 2-4x the price of other receivers
  • Closed ecosystem. Only plays nice with Trimble software
  • License and support fees can add up fast

It performs well, but it’s quite difficult to justify its power unless you’re already heavily invested in Trimble workflows.

Leica GS18: Smart Tilt, Smart Design

Similar to the Trimble R980, the Leica GS18 is a good choice if you are already using equipment in the Leica family. Total station users can opt for this receiver if they want a premium choice of RTK. The unique feature here is the GNSS + IMU tilt compensation. It is a huge advantage in complex sites where leveling the pole is tough.

Leica GS18 Key Features

Let’s separate some features why it becomes a surveyors’ choice:

  • GS18T model uses real-time tilt correction
  • Leica SmartTrack and SmartCheck technologies
  • Deep integration with Leica Captivate software
  • Solid GNSS tracking, especially in open environments

The tilt compensation is smooth and reliable. Surveyors who are moving between total stations and GNSS systems will appreciate the familiarity and integration. But keep in mind that this is a premium instrument that does what it says but at a cost.

Downsides Of Leica GS18

Users that are loyal to Leice will truly value this choice. Especially if Leica total stations are already in use. However, here is what to keep in mind if something about that description doesn’t match with you:

  • Price. Often cheaper than Trimble, but still more expensive than many other receivers
  • Software tie-in. Best performance comes only with Leica Captivate
  • Support footprint in Canada is more limited, especially outside of Manitoba and western markets

Ultimately, if you’re building a GNSS system from scratch or want open interoperability, it may not be the best starting point.

Which One Should You Choose?

Let’s gather all the specs and decide, which one is better option based on your needs:

  • Hemisphere S631. It offers nearly the best mix of performance, flexibility, and value. Its ecosystem is open and it works well with FieldGenius, which means strong support for you from Bench-Mark across Canada.
  • Trimble R980. This generous choice will bring you the top performance. However, it comes at a high price and really ties you into the Trimble ecosystem. Great if you’re already using Trimble gear.
  • Leica GS18. This receiver is ideal for Leica users upgrading from total stations in the Leica family. It performs well but works best within the Leica software environment. This can be limiting and less supported in parts of Canada.

Frequently Asked Questions

Is the Hemisphere S631 compatible with FieldGenius software?

Yes. The S631 is fully compatible with FieldGenius. You’re not locked into proprietary software like with Trimble or Leica. It allows you to use open and widely supported field applications.

How does the tilt compensation on the S631 compare to the R980 and GS18?

The Hemisphere S631 uses an IMU-based tilt system that works out of the box with an easy 30 second calibration routine. The Trimble R980 and Leica GS18 offer excellent tilt systems, and S631 delivers similar real results at a lower price point.

Why is the Trimble R980 so much more expensive than the S631?

The R980 is part of a proprietary ecosystem that includes Trimble Access, Trimble Business Center, and no ability to use other software packages. You’re buying into an integrated system.

Can I switch from a Leica or Trimble system to Hemisphere S631 easily?

Yes. In fact, many of our customers do exactly that. Because the S631 works with open software like FieldGenius, the transition is smooth. Bench-Mark also offers training and onboarding support to help you migrate your workflows.

What makes the Hemisphere S631 such a strong choice for Canadian surveyors?

It’s a combination of rugged field reliability, excellent GNSS performance, and Canadian-based support. You’re working directly with Bench-Mark’s experienced team, who serve all of Canada from the office and support platform.
