Product Review South Galaxy G6

South Galaxy G6 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 G6 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 G6 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. 

Full satellite constellations support

Equipped with most advanced GNSS boards, SOUTH Galaxy G6 system can track most signals from all kinds of running satellite constellations, especially supports the signals from Beidou3, also is able to get position result only with Beidou signal.

Supports PPP services

Galaxy G6 is able to access the RTX services with tracking L-Band signals, really achieves the goal of precise single-point positioning without a reference, the positioning is no more constrained by terrain environment, such as mountain, wasteland, desert, island, fixed solution is generally available as long as the GNSS constellations are visible.

Unlocked feature–xFill

Integrated with high-performance GNSS board, Galaxy G6 supports the new service that extends RTK positioning for several minutes when the RTK correction stream is not available.

IMU auxiliary tilt measurement

The inbuilt professional IMU sensor is able to greatly improve the productivity of RTK measurement because of its excellent performances, fast initialization, calibration-free, not affected by magnetic environment. Rapidly measures points without leveling instrument, as long as pole tip reaches the target.

Shake tilt measurement

It’s a tilt measurement technology based on the patented core algorithm. No magnetic sensor use, calibration-free, anti-jitter, unlimited tilt angle

Web UI management platform

Embedded Linux operation system+SOUTH intelligent cloud platform. The receiver is no longer an independent hardware device, it’s a complete intelligent operation system with web page cloud platform. Accessing to the internal Web UI of galaxy G6 supports WIFI or USB connection. Users can monitor the receiver status and configure it via the internal Web UI management platform.

Intelligent data communication

Built-in network module. Equipped with standard 4G module which supports TDD-LTE/FDD-LTE 4G network, and downward compatible with WCDMA/CDMA2000 3G and GPRS/EDGE 2G network. Smart PPP dialing technology can auto dial which makes the Galaxy G6 keeping online continuously during the survey.

Built-in functional digital radio. SOUTH self-developed digital radio which can fully support the communications with the mainstream radio protocols: Trimtalk450s, SOUTH, SOUTH+, SOUTHx, huace, ZHD, Satel. Realize the random switching of the radio range 403MHz-473MHz and the power level as well.

Radio repeater: The rover can broadcast the corrections via internal radio to other rovers after receiving the radio differential signal from Base station.

Internet repeater: The rover can broadcast the corrections via internal radio to other rovers after received the network differential signal from CORS station.

Intelligent storage technology

• Internal 8G storage supporting external U disk storage

• Supporting STH, Rinex format, sample frequency can reach to 50Hz

• Automatic circular storage, delete the primary data once the disk is full automatically

• On-key intelligent copy, supporting direct data copy by external U disk

HD LCD

0.96 inch HD OLED colorful LCD. supporting multiple language display 50Hz and it is suitable to field work with high brightness and low power consumption.

Intelligent temperature control technology

Built-in several thermometer sensors, intelligent temperature control technology, monitor and adjust the receiver temperature real time and guarantee the best work status.

Intelligent power supply technology (Optional)

• Long endurance removable lithium battery which can display the remaining power real time

• Equipped with large capacity portable power source which supply the power continuously

• Adopting intelligent power saving mode, rising the endurance time 20% under the normal work mode

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 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.

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.
