Frequently Asked Questions

General

✓ What level of accuracy can I expect from the South G4 GNSS receiver? ▾

The South G4 GNSS receiver delivers professional-grade accuracy suitable for all surveying applications. With its advanced multi-constellation tracking capabilities across 1698 channels, it provides centimeter-level precision in both RTK and static survey modes, making it ideal for cadastral surveys, construction layout, and topographic mapping.

✓ How does the 60° tilt compensation feature work in field conditions? ▾

The integrated 60° tilt compensation allows you to maintain survey-grade accuracy even when the pole is not perfectly vertical. This IMU-based technology automatically corrects for pole tilt, significantly reducing setup time and eliminating the need for precise bubble leveling, while ensuring consistent point accuracy across varying terrain conditions.

✓ What is the effective range of the 12km UHF radio communication? ▾

The 12km UHF range provides exceptional radio communication coverage for RTK corrections between base and rover units. In optimal conditions with clear line-of-sight, you can achieve the full 12km range. However, actual range may vary depending on terrain, vegetation, and atmospheric conditions. This extended range significantly reduces the need for intermediate repeaters in most surveying projects.

✓ How many satellite constellations does the 1698-channel system track? ▾

The South G4's 1698-channel architecture simultaneously tracks all available GNSS constellations including GPS, GLONASS, Galileo, BeiDou, and QZSS. This comprehensive multi-constellation capability ensures maximum satellite visibility and availability, particularly beneficial in challenging environments such as urban canyons, dense forest canopy, or mountainous terrain where satellite obstruction is common.

✓ What makes the South G4 suitable for harsh field environments? ▾

The South G4 is engineered for professional surveying durability with IP67-rated housing providing complete protection against dust and water immersion. Its robust construction withstands extreme temperatures, shock, and vibration typical of construction and field surveying environments. The sealed design and military-grade connectors ensure reliable operation in rain, dust storms, and temperature extremes.
