South Galaxy G1 PLUS RTK GNSS receiver is equipped with a 220 channel Trimble BD970 or 336 channel BD990 GNSS board. In combination with an RTK Subscription this receiver is capable of providing centimetre accuracy in real time. Because The South Galaxy G1 PLUS supports GPS, Glonass, Galileo, Beidou, QZSS, IRNSS and SBAS satellite constellations it is capable of achieving this centimetre accuracy in tough conditions. Down below you can find which frequencies it supports. This receiver is also equipped with patented advanced RF Spectrum Monitoring technology. This features allows you to detect low quality satellite signals and applying filters to them to increase the overall stability. It allows you to get an RTK fix in the most inaccessible locations with poor satellite coverage.  The Galaxy G1 PLUS has a standard tilt sensor that can go up to 30 degrees tilt but it can be upgraded with an IMU tilt sensor. This can be used for tilt surveying up to 60 degrees. Currently the IMU feature is only compatible with the South SurvX software and Microsurvey FieldGenius.

Recommended Setup by Manufacturer

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 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.

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 independantly 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.

    Hi I am interested in the South Galaxy G1 Plus.
    I currently have a Trimble R8 RTK that use with a Toughpad FZ-G1 and the software 4site
    https://appsincadd.co.uk/n4ce/survey
    I need to know if the Galaxy G1 will work with my 4 site software.
    I have spoken to the writer of the 4 site software and I am told that I would need to access the RTK corrected NMEA data via bluetooth.
    Is this possible?
    I don't want to have to buy an additional logger so i would need to be able to access the units interface to change the settings .
    Do you know what the vertical accuracy is using just RKT.
    I am a bit concerned about where I would be able to get repairs and additional batteries from do you sell them or know where I could get them from.
    Ideally I would like to see one before I buy, do you have any in the UK I could look at.

    Many thanks for your help,

    Mark

    Hi Mark, 

    Happy to help you with this! 

    • Regarding the NMEA data stream, yes the Galaxy G1 PLUS is capable of sending corrected NMEA data via bluetooth. You can insert a sim card into the receiver, then setup your RTK subscription in the receiver itself. This way the data is already corrected for when the software itself doesn't have an NTRIP client.
    • There is no need to buy another logger. You can access the interface of the Galaxy G1 PLUS on any device you like. This works via WiFi and internet browser. 
    • On average RTK is around 1-2 centimeters accurate. I suggest using RTK Direct. They cover the UK as well. Subscriptions start as low as €9.5
    • We can do repairs for you on this model if needed, you get of course factory warranty as well. We also sell the original South batteries
    • We do have customers in the UK that use the Galaxy G1 PLUS. If you want we can set up a video call, so you can see it working. We have them in stock here at the moment so this is possible.

    I hope this answers all your questions and I'm looking forward hearing back from you!

    Kind regards,

    Dear, Is there a controller in the selling package?
    If not can it be used by tablet or android phone.
    Do I need to buy something plus?

    Hi Ivan,

    No there is no controller included in this package. Recommended with this receiver is the South H5 android controller.

    If you want you can use your own tablet as well. Just make a standard bluetooth connection and you're good to go:)
