Hemisphere S631

The Hemisphere S631 is the latest GNSS receiver from Hemisphere. The S631 takes everything that made the beloved S320 and S321+ receivers so great and improves upon those ideas. The hot swappable batteries and compact size were adopted from the S320 and further improved upon, while the robust RTK engine and great Satel radios were taken from the S321+. Sporting the brand new Phantom P40 board, the Hemisphere S631 offers unparalleled performance.


Tilt Surveying

The Hemisphere S631 finally allows for tilt shots while surveying, up to an angle of 60°. With a 60° internal tilt sensor, you can get shots you thought were otherwise impossible. Whether the point is under a vehicle or directly next to a building, you can tilt the receiver to an angle where it can see more of the sky, ensuring your accuracy. The internal tilt sensor in the S631 offers 2 cm of compensation at 30° or 5 cm at 60°. Never have the calibration of your pole impact your results again.


Better Performance

With the new Phantom P40 board, the Hemisphere S631 now sees; GPS; L1CA, L1P, L1C, L2P, L2C, L5, GLONASS; G1, G2, G3, P1, P2, Beidou; B1i, B2i, B3i, B10C, B2A, B2B, ACEBOC, GALILEO; E1BC, E5a, E5b, E6BC, ALTBOC, QZSS; L1CA, L2C, L5, L1C, LEX, IRNSS; L5 and Atlas. With this many different constellations and signals, you get better performance in multi-path environments. With the improved infrastructure of the Phantom P40 board, the S631 is designed to take advantage of everything available to it. This is the receiver designed to be future proof.


Designed Around Surveying

The Hemisphere S631 is designed to make surveying easy. With the internal cell modem and powerful 1 Watt internal radio, the S631 is designed to give you the flexibility to work around your projects. You can choose the communication settings that meet the requirements for your job. With the hot swappable batteries, there is no need to stop in the middle of the day and reconfigure your base and rover as the batteries die. Simply keep an extra set of batteries on hand and keep working as long as you need. Not that you should ever have to swap batteries as the S631 can run for 9 hours off a single set of batteries. This is the receiver that works as long as you do. The entire receiver is protected by a magnesium alloy enclosure that is rated for a 2 m pole drop, and is completely dust and waterproof.

  1. Cam Christianson

    The S631 really feels like an upgrade over the last generation. It feels better built, and the in-foliage and tilt performance is really convenient.

  2. Reid Ostenberg

    The radio range of the S631 has been blowng me away. I haven’t even had to use my external radio. When paired with FieldGeniu, I get an easy-to-use solution that has all of the tools I need.

  3. Allan Andres

    The tilt feature is wonderful, and the S631 works so well under canopy! I was a bit worried about moving to FieldGenius, but it is easy to use once I had it figured out.

  4. Sid Sandback

    We love the tilt capacity on the S631, and we cannot say enough about the Bench-Mark support. We also love the Graphical Layout in FieldGenius, it’s so easy to use.

  5. Tom Mehdi

    The S631 has been great, with tilt we are a lot faster, and the in-canopy performance is making a big difference. Once I got used to FieldGenius, i found it to be way faster.

  6. Shamus McGee

    We love the fact that the S631 has a 10 km base-to-rover range, and that they will fix any constellation. FieldGenius has to been the easiest and most user-friendly surveying software we have ever used.

  7. Rudi van der Merwe

    The S631 gives us consistent and accurate results in mountainous and foiliage-covered terrain. We found that FieldGenius was easy to learn and we keep discovering more powerful features.

  8. Connor Traves

    The RTK-fixed coverage with the S631 has been vastly improved over the older S321. FieldGenius has freed up our drafters, and made construction layout a breeze.

  9. Dustin Hicke

    The field crews appreciate how light it is compared to the other models. In addition, the tilt sensor is a great featureto help speed up our fieldwork.

  10. Greg Skelhorn

    The S631 is proving itself to be reliable and fast in all conditions. We have seen a definite performance boost with the addition of the S631.
