RELIABLE IN THE FIELD
SinoGNSS T300 GNSS receiver is a compact RTK GNSS receiver tracking all working constellations, which performs well with each constellation independently. With SinoGNSS QUANTUMTM Generation III technology and its strong anti-interference design, the T300 provides available and reliable high-precision positioning information no matter where you are.
RUGGED AND EASE OF USE
The rugged housing with IP67 Dustproof & Waterproof design makes the T300 work perfectly and effectively even in harsh environments. Small volume with less than 1kg weight makes the T300 one of the most portable GNSS receivers which can meet your RTK survey demands. Bulit-in 8GB internal memory enlarges your data storage in the field.
INTEGRATED GNSS RECEIVER
The T300 GNSS receiver combines a GNSS board, Bluetooth® and adjustable TX/RX UHF into one compact device, which is one of the most reliable choices for any surveying tasks. Built-in GPRS/ GSM/4G modem ensures the T300 work seamlessly with all kinds of CORS.
SMART BATTERY DESIGN
With two hot swap batteries, the T300 extends working hours and ensures your fluent workflow in the field. The battery LEDs flash when battery runs low. The consumer-grade battery design is compatible with Canon LP-E6, which is easy to purchase and replace in your local market.
