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.
