Description

Stonex S990A Product Review

Stonex S990A is a 800 Channels GNSS receiver characterised by a new feature that enhance the performances of field surveys. The new IMU System allows tilted measurement (TILT) up to 60°: quick initialisation, fast and precise survey. S990A Receiver is equipped with all important connectivity capabilities: Bluetooth, Wi-Fi, UHF radio and 4G modem. The internal battery of 10.200mAh allows to work for 9 hours and can be recharged via a type-c connector. The color touch display and the WebUI are an easy and fast way to have the complete control of the receiver. Thanks to aRTK function and Atlas® correction service, Stonex S990A is also able to work in particularly difficult areas. Atlas® delivers world wide centimeter level correction data through L-band communication satellites. 1PPS can be applied to scenarios that require precise synchronisation time to ensure that multiple facilities work together or that use the same parameters for system integration based on precise time.

S990A 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 Apglos, Carlson, Aplitopand 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 choosen 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.

  • 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.
