Description

Sokkia GRX3 Product Review

The Sokkia GRX3 GNSS Receiver is a powerful satellite system packed with the top-class GNSS technology which is built for static and kinematic land surveying applications. It features the innovative nine-axis inertial measurement unit (IMU) and the ultra-compact eCompass that balances if mis-levelled up to 15 degrees. This Sokkia construction tool comes with the leading Fence Antenna that offers 226 tracking channels with a Universal Tracking Technology that support all modernised signals.

The Sokkia GNSS receiver comes with an integrated Bluetooth and multi-channel Sitecomm Technology that connects to Sokkia data collectors when identifying field locations. This GNSS receiver is used together with the Sokkia Receiver Utility (SRU), MAGNET Field, and the Sokkia GeoPro software which gives real-time communication, cloud storage, data collection, topographic staking, roads and the like. It features adjustable Phase Locked Loop (PLL), Delay Locked Loop (DLL) that provide great signal reception in weak-signal environments. Plus, the GRX3 receiver supports the Quartz Locked Loop (QLL) technology that is used in high-vibration environments.

With an IP67 dust proof and water resistant rating, the GRX3 receiver is also vibration and shock resistant to endure rugged and harsh environments. It also features a built-in 8GB memory storage and an internal battery that avoids any downtime in the job site. As an additional feature, the Sokkia GRX3 can access data by USB read only.

 

 

 

  • 226 Channels
  • GPS, Glonass, Galileo, Beidou, QZSS, IRNSS and SBAS
  • UHF radio on 410-470Mhz frequency for rover/base setup
  • USB
  • Bluetooth
  • RS-232
  • 4G mobile data
  • IP67

 

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

  • Surveying
  • GIS applications
  • Earthworks
  • Roadworks
  • Construction

 

 

Depending on your requirements you have the following options:

  • 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, 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. If you need help, feel free to contact us by phone or via the chat below!

  • 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.
  • 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.

 

Comparable receivers from other brands

Global GPS Systems is currently in the process of independently testing every single receiver on the market. In collaboration with an highly recognised surveying company we will be testing all receivers on its performance in increasingly more difficult environments, accuracy claims, Time to first fix, cold start and more.
