Powerful Precision Performance

Equipped with an advanced 1408 channels GNSS board and capable of supporting multiple satellite constellations, including GPS, GLONASS, BEIDOU, GALILEO, and QZSS. Stonex S850+ GNSS receiver is an ideal solution for any surveying field work.

S850+ has also L-Band correction which gives the S850+ excellent signal tracking ability and interference resistant capability. Portability and speed of operation make the S850+ GNSS receiver particularly suitable for fieldwork in areas of complex terrain.

Stonex S850+ is equipped with all the necessary connections including integrated Bluetooth and internal Wi-Fi functionality; it also has a built-in dual frequency UHF radio, 410-470 MHz / 902.4-928 MHz and the worldwide compatible 4G GSM modem.

Stonex S850+ features a new IMU System that allows tilted measurement (TILT) up to 60°: quick initialization, fast and precise survey.

MULTI CONSTELLATION Stonex S850+ with its 1408 channels, provides an excellent on board real time navigation solution with high accuracy. All GNSS signals (GPS, GLONASS, BEIDOU, GALILEO, QZSS and IRNSS) are included, no additional cost.
DOUBLE FREQUENCY RADIO The S850+ has an integrated UHF double frequency radio, 410-470MHz and 902.4-928MHz. Use the 4G GSM for a fast internet connection in any location.
ELECTRONIC BUBBLE + IMU The S850+ has an E-bubble that displays if the pole is vertical on the software. The point will be recorded automatically when the pole is level. The optional IMU add-on negates the need to level your pole, allowing you to provide fast and accurate measurements that were previously unaccessible.
HIGH BATTERY CAPACITY AND TYPE-C The Stonex S850+ has a large capacity lithium battery and Type-C connector to recharge it easily.
RUGGED RTK With IP67 Certification, the Stonex S850+ will ensure operations in every kind of tough environment.

S850+ - Atlas GNSS Global Correction Service

All S850+ receivers come include 3-month Atlas Service Land Near Shore to be activated within 12 months.

Atlas is an innovative, industry-leading GNSS-based global L-band correction service, providing robust performance at competitive market prices. Atlas is a flexible and scalable service, delivering its correction signals via L-band satellites at accuracies ranging from meter to sub-decimeter levels. Leveraging more than 200 reference stations worldwide and with L-band satellites distributing Atlas corrections, the entire globe is virtually covered. The Atlas GNSS global correction service provides correction data for GPS, GLONASS, BeiDou, and Galileo constellations.

Atlas correction service is available on all Hemisphere Atlas-capable single- and multi-frequency, multi-GNSS hardware.

When using multi-frequency hardware, Atlas corrects more satellites than ever before, which creates faster convergence times and is robust and reliable in canopy or foliage covered areas. With both single- and multi-frequency hardware, Atlas achieves instant global sub-meter positioning accuracy, comparable to, and typically more robust than SBAS, since Atlas corrections contain data from multiple available constellations.

Systems supporting Atlas utilize Hemisphere’s world-class Athena™ GNSS RTK engine. Athena often exceeds performance offered by other industry leaders and provides a future-proof foundation enabling market-defining performance, flexibility, and reliability.

Atlas Basic
Atlas Basic provides users of both single- and multi-frequency Atlas-capable products the ability to achieve SBAS equivalent performance anywhere
in the world where the Atlas correction service is available. Atlas Basic is a ground-breaking new feature that offers a proven accuracy of 30 to 50 cm (95%)*. Atlas Basic offers instantaneous sub-meter accuracy allowing for DGPS-level accuracy within the global regions supported by Atlas.

* Depends on multipath environment, number of satellites in view, satellite geometry, and ionospheric activity.

Industry-Leading Capabilities

• Positioning Accuracy: Atlas provides competitive positioning accuracies down to 4 cm RMS in certain applications, often exceeding competitive systems’ capabilities
• Positioning Sustainability: Cutting-edge position quality maintenance in the absence of correction signals, using Hemisphere’s Tracer™ technology
• Convergence Time: Industry-leading convergence times of 10 – 40 minutes
• Global Ionospheric Model: Real-time ionospheric activity and data is sent to the receiver and allows Atlas-capable devices to adjust accordingly, providing excellent convergence performance

Scalable Service Levels
