Powerful Precision Performance

The Stonex S900+ is an advanced surveying system that features a high-performance GNSS board with 1408 channels, enabling it to support multiple satellite constellations such as GPS, GLONASS, BEIDOU, GALILEO, and QZSS. This system comes equipped with a 4G GSM modem that guarantees a fast internet connection, which allows for the reception of correction data and the execution of accurate surveys.

With its sleek and compact design, the S900+ is equipped with Bluetooth and Wi-Fi modules, ensuring a reliable data flow to the controller. Additionally, an integrated UHF TX/RX radio makes the S900+ an ideal choice for a GNSS Base + Rover system. Furthermore, the S900+ has the optional IMU technology, allowing for quick initialization and tilt up to 60°. With just a single click, corrected coordinates of a point can be obtained.

What are the advantages of the S900 with IMU? • Fast initialization • Up to 60° inclination • 2 cm accuracy 30° • 5 cm accuracy 60° • Fast and precise survey • No problem of electromagnetic disturbances

MULTI CONSTELLATION Stonex S900+, with its 1408 channels, is an excellent on board real time navigation solution with high accuracy. All GNSS signals (GPS, GLONASS, BEIDOU, GALILEO and QZSS) are included, at no additional cost.
DOUBLE FREQUENCY RADIO The S900+ has an integrated UHF double frequency radio, 410-470MHz and 902.4-928MHz. Every application can now be used with the S900+
ELECTRONIC BUBBLE + IMU The S900+ has an E-bubble that displays if the pulse 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.
TWO INTELLIGENT BATTERIES The dual slot for two Smart hot swappable batteries gives you up to 12 hours of battery life. The power level can be checked and seen on the controller or directly on the led bar on the battery.
4G MODEM The Stonex S900+ has an internal 4G modem that integrates with signals around the world.

S900A - Atlas GNSS Global Correction Service

All S900A 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
Service Level – Position Accuracy
Atlas Basic – 50 cm 95% (30 cm RMS)
Atlas H30 – 30 cm 95% (15 cm RMS)
Atlas H10 – 8 cm 95% (4 cm RMS)
