Modular GNSS System

Stonex S700A is a compact, high-performance GNSS receiver featuring a multi constellation 700 channels GNSS board.

The customer has the ability to purchase an entry level version - only L1 GNSS and, at any time, it is possible to upgrade the receiver to the full version via an activation code.

S700A supports GPS, GLONASS, BEIDOU, GALILEO, QZSS and IRNSS. The S700A full version also supports L-Band correction.

The unique internal antenna combines GNSS, Bluetooth and Wi-Fi integrated modules to optimize space and increase performance. This technology provides stronger and cleaner signal monitoring, which leads to more reliable results. Designed for all day use in surveying application, S700A includes several features:

• Linux Operating System
• WEB UI interface
• 4G Modem
• high battery capacity
• Type-C connector
• IP67 certification.

Stonex S700A GNSS receiver full version, thanks to aRTK function and Atlas® correction service is an ideal solution for any surveying field work in particularly difficult areas. Atlas® delivers world wide centimetre level correction data through L-band communication satellites.

MULTI CONSTELLATION All GNSS signals (GPS, GLONASS, BEIDOU, GALILEO, QZSS and IRNSS) are included, at an additional cost.
WEB UI CONTROL To initialize, manage, monitor the settings of the receiver and to download data, easily connect to a PC or smartphone via Wi-Fi.
TWO VERSIONS The ability to purchase an entry level version and then upgrade the receiver to the full version provides flexibility to all professionals in the field.
HIGH BATTERY CAPACITY AND TYPE-C The Stonex S850A has a large capacity lithium battery and Type-C connector to recharge it easily.
4G MODEM The S700A has an internal 4G modem that operates with all world signals.

S700A - Atlas GNSS Global Correction Service

All S700A 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)
