Stonex S900 Product review

The GNSS receiver S900 is the result of the continuous evolution of the Stonex GNSS integrated receivers. Featuring a high accuracy multi constellation antenna, a powerful UHF dual frequency transmitter and a GSM 4G modem, for a fully integrated multi-communication choice; all combined with a light and modern design.

Stonex S900 integrated GNSS receiver tracks all the present constellations and satellite signals GPS, GLONASS, BEIDOU, GALILEO, QZSS, IRNSS and through the upgradable firmware offers the opportunity to be day by day updated with the latest available features

. On S900 it is possible to insert 2 smart hot swappable batteries at the same time, ensuring a maximum of 12 hours of operation without stopping. To initialise, manage, monitor the settings of the receiver and to download data is available a user friendly Web UI. S900 is also equipped with E-Bubble functionality and the optional IMU technology. Fast initialisation, up to 60° inclination.

S900A description

Stonex S900A is equipped with an high performance GNSS board 800 channels and capable of supporting multiple satellite constellations: GPS, GLONASS, BEIDOU, GALILEO, QZSS and IRNSS, including L-Band correction. Through the 4G GSM modem a fast internet connection is guaranteed for the reception of correction data and the management of the maps in the background. In the amazingly compact structure the Bluetooth and Wi-Fi modules allow always reliable data flow to the controller, and the integrated TX/RX UHF radio with selectable frequencies, make S900A the perfect system for a GNSS Base + Rover. Stonex S900A integrates E-Bubble sensor that allows the measurement of difficult points with the pole not levelled. It is possible to measure points with an inclination of the pole up to 30° even in harsh environments and in the presence of magnetic fields. S900A is also equipped with the optional IMU technology. Fast initialisation, up to 60° inclination.

S900 applicable industries

This receiver can be used in all applications where a centimetre accurate position is needed:

• Surveying
• GIS applications
• Earthworks
• Roadworks
• Construction
• Agriculture
• Mapping
• Landfill
• Hydrographic
• UAV Base Station

Rover setup

When using this device in a rover configuration you may need the following accessories besides the receiver itself

• RTK Correction service. To achieve centimetre accuracy your receiver will need RTCM correction data so it can calculate your exact position. Without an RTK provider your receiver won’t be able achieve a 1-2 centimetre accuracy.
• Surveying software. Your receiver provides you with the coordinates you need but you still need surveying software in order to process this information. Which software you need depends on your needs. We recommend keeping it simple and don’t pay for things you don’t need. Having that said, if you do have to do complicated surveying work make sure you get the right software. Some recommended options are Carlson, Aplitop and FieldGenius. If you need help, feel free to contact us by phone or via the chat below!
• Data collector. You might need a tablet or controller to run your software on. The type of tablet depends on which software you have chosen as some are Android based and some are Windows.
• Bracket and Holders. These are used to connect your tablet to your surveying pole so the whole set is easier to handle.
• Surveying pole. In order to get the best performance out of your receiver you want to minimise the disturbances around you and give it a clear sight to the satellites above. That why its recommended attaching your receiver on a 2 meter minimum surveying pole. These come in fixed rods and in telescopic rods.

Rover/Base setup

When you don’t have access to an  RTK network you might have to setup your own base station in order to receive corrections. These are the accessories you might need besides the receiver itself:

• A second RTK GNSS receiver. preferably from the same brand. If you already have another one, then make sure they run on the same frequency.
• Surveying software. Your receiver provides you with the coordinates you need but you still need surveying software in order to process this information. Which software you need depends on your needs. We recommend keeping it simple and don’t pay for things you don’t need. Having that said, if you do have to do complicated surveying work make sure you get the right software. Some recommended options are Apglos, Carlson, Aplitop and FieldGenius.

That why its recommended attaching your receiver on a 2 meter minimum surveying pole. These come in fixed rods and in telescopic rods.
• Tripod and Tribrach. These are needed to setup your base station with the second receiver. The Tripod gives good stability so errors in sudden movements of the base station are avoided.
• External Radio. Most RTK GNSS receiver have an internal UHF radio build in. However, sometimes the power output is not strong enough to give you the workable distance you need and an external radio required. Internal radios can go up to 3 Watts that can work up to 8km. External radios can easily achieve 35 Watt outputs, thereby increasing your working range.
