Foif a90 Gps Rtk Gnss Receiver Rtk Gps Gnss Surveying Base And Rover GNSS RTK
Product Features
The foif a90 is a high-precision RTK (Real Time Kinematic) surveying instrument that excels in the field of engineering surveying. Here is a detailed evaluation of its features:
I. High-Precision Measurement
Static Measurement Accuracy: The planimetric accuracy reaches ±(2.5mm+0.5ppm) RMS, and the elevation accuracy reaches ±(5mm+0.5ppm) RMS, meeting the demands of high-precision engineering surveying.
RTK Measurement Accuracy: The planimetric accuracy is ±(8mm+0.5ppm) RMS, and the elevation accuracy is ±(15mm+0.5ppm) RMS, maintaining high accuracy even during dynamic measurements.
II. Comprehensive Satellite System Support
The foif a90 supports a full range of satellite systems including BDS (BeiDou), GPS, GLONASS, Galileo, SBAS, IRNSS, and QZSS, with up to 555 channels, ensuring rapid and accurate satellite signal reception in various environments.
III. Powerful Performance
Rapid Initialization: The initialization time is less than 10 seconds, with a reliability of 99.9%, enhancing measurement efficiency.
Waterproof and Dustproof: With an IP68 rating, the instrument is designed to be stable and durable in harsh environments.
Smart Battery: The battery has a large capacity, providing long endurance, and features a battery level indicator for convenient monitoring.
IV. Convenient Operation and Expandability
Built-in Bluetooth and WiFi: Supports Bluetooth and WiFi connections, allowing direct connection to a handheld device via WiFi instead of Bluetooth, improving data transmission efficiency and convenience.
Differential Output: Supports multiple differential output formats such as RTCM2.3, RTCM3.X, RTCM3.2, CMR, and CMR+, accommodating various user needs.
Built-in Storage and Expandability: Equipped with 8GB of onboard memory and supports TF card expansion up to 32GB or more, ensuring data storage and backup.
V. Rugged and Durable Design
Shell Material: Made of magnesium-aluminum alloy, the shell is sturdy and reliable, with a certain degree of shock resistance.
Integrated Design: The entire circuit adopts plug-in connections, eliminating quality issues caused by loose cables. The internal partitions are CNC-machined, enhancing internal heat dissipation, signal shielding, and structural stability.
VI. Wide Range of Applications
The foif a90 is suitable for engineering surveying and coordinate staking work in various fields such as electricity, transportation, construction, and water conservancy, meeting the high-precision measurement needs of different industries.
In summary, the foif a90 stands out in the field of engineering surveying with its high-precision measurement, comprehensive satellite system support, powerful performance, convenient operation and expandability, rugged and durable design, and wide range of applications. It offers high cost-effectiveness and competitiveness in the market.
