Trimble R8 multi-mode GNSS receiver supporting static, fast static and RTK surveying for control survey and construction stakeout.
Overview
The R8 GNSS receiver is a multi-mode satellite positioning receiver supporting RTD, SBAS pseudorange differential, high-precision static, fast static and conventional/network RTK modes. It meets horizontal and vertical positioning accuracy requirements for control surveying, topographic surveying, engineering stakeout and deformation monitoring. The rugged, lightweight design is suitable for field survey teams working on road, bridge and tunnel construction projects.
Applications
• Control survey and topographic mapping for road and bridge projects
• Construction layout and stakeout on highways, railways and buildings
• Deformation monitoring of bridges, tunnels and high-rise structures
• Third-party surveying and mapping services
Features
• Rugged housing with water and dust resistance for harsh environments
• High measurement accuracy with stable repeatability
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Trimble R8 GNSS Receiver comply with?
A1: The Trimble R8 GNSS Receiver is designed and manufactured in accordance with relevant Chinese national (GB) and industry standards, as well as applicable international standards. A calibration certificate is provided with each unit.
Q2: How often should the Trimble R8 GNSS Receiver be calibrated?
A2: We recommend annual calibration by iRoad authorized technicians. For high-frequency use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. iRoad provides on-site installation and operator training for major equipment; remote video guidance is available for portable instruments.
