Hemisphere was founded in 2002, and has provided industry leading GNSS positioning solutions. First breaking into the agriculutre positioning market, Hemisphere has become a main stay of the agriculture industry under the brand name OutBack. Branching out from agriculture, Hemisphere has provided leading positioning technology in the form of their Vector marine products, and their industry best S-Series of surveying equipment.
Hemisphere is known for their high-performance, high-precision and reliable GNSS products that take full advantage of the latest signals and constellations. Hemisphere’s products are designed to provide accurate and reliable positions even in difficult multi-path and high interfence environments. Hemisphere receivers are industry leader’s in multi-path positioning and can out-perform or match any reciever on the market.
Hemisphere GNSS is head-quatered in Scottsdale Arizona, and has several offices across North America, including in Calgary Alberta and Winnipeg Manitoba. What this means for you is, that all support and service is provided in your time zone. There is no need to ship anything overseas, meaning quick turn-arounds on any repairs. Here at Bench-Mark we have been Hemisphere wholesale distributors for over 10 years. We have watched Hemisphere improve their survey offerings from the dual-frequency S320 all the way to the multi-GNSS and multi-frequency S631 reciever.
The Hemisphere S631
The Hemisphere S631 is the latest survey receiver from Hemisphere, and boasts all of the latest RTK technology they have to offer. It is a multi-frequency, multi-GNSS reciever that is the best performing receiver to date.
The Hemisphere S631 can receive corrections from all of the major constellations including; Galileo, BeiDou, GPS and Glonass. With the ability to fix off any constellation the S631 can take the best available corrections to determine its position.
GLONASS: G1/G2/G3, P1/P2
SBAS and Atlas
Superior Multi-Path Performance
The Hemisphere S631 provides best in class under canopy performance. The S631 uses Hemisphere’s proprietary Athena RTK engine. The Athena RTK engine is designed to utilize all of the signals that are available today. With access to the higher power, and multi-path mitigating L5 signals on all available constellations, the S631 can perform under dense canopy.
Under Canopy Repeatability
The S631 is not just faster to fix under canopy. They are also accurate, repeatable and reliable. With the Athena RTK engine, you have an engine that filters and disregards solutions that have been affected by multi-path.
With Sure-Fix technology, the S631 uses two independant and distinct RTK engines to derive a solution. Only once the two agree will the solution be reported as Fixed+. With SureFix you can be confident in your position, and avoid having to reshoot a position multiple times.
The 7th Generation technology inside of the Hemisphere S631 is the most advanced positioning technology on the market.
Advanced IMU tilt Sensor
One of the biggest advantages of the Hemisphere S631 over the last generation of recievers is the introduction of the Inertial Measurement Unit (IMU). The IMU inside of the S631 integrates RTK data with the inertial sensor to get an accurate position. By integrating RTK data into the IMU sensor, you do not have to worry about orientation or calibration.
The IMU tilt sensor can be calibrated in as little as 30 seconds, with a very simple rocking motion. All you have to do is hold the point of the pole on the ground and rock it back and forth to calibrate the sensor. The quick procedure takes no time in the field and you are ready to start surveying right away.
Extended Range, Battery and Durabilty
The S631 boasts powerful internal 1 W Satel radios, that can provide up to 10 km of base to rover range. The internal Satel radio is capable of broadcasting many of the most common and popular radio formats, including; TrimTalk, Pacific Crest, TrimMark and Satel. With the ability to program and edit your frequencies, message types, protocols, and more you can always find radio settings that will work with your existing equipment. When you need a little bit more range, the S631 can broadcast corrections over a cellular network with the use of StormCaster.
The S631 is encased in a magnesium housing that provides dust, shock and water proofing. WIth an IP67 environmental rating, and a MIL-STD-810G rating, you can be assured that the Hemisphere S631 will stand up to whatever you throw at it on site. Whether it falls from your truck, pole or your tripod is blown over the S631 can take any impact you throw at it.
The S631 supports all of this processing and radio power with long lasting battery. There are two batteries that can be hot swapped in the reciever, that allows for up to 12 hours of continuous range. The batteries both have smart battery indicators to indicate how much charge remains in the battery.
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.
