Meridian MBase

MBase High Performance Base Receiver

The MBase GNSS receiver is a fully integrated, professional-grade GNSS base station tailored to address 95% of surveyors’ requirements for UHF GNSS base and rover operations. It also has built-in 4G connectivity, Bluetooth, Wi-Fi, and a 5W data transmission radio, enabling high-speed data transfer and user-friendly WebUI, which improves efficiency and convenience. The MBase has a rugged design, making it suitable for outdoor and harsh environments. Equipped with a 5-watt radio module, it ensures reliable GNSS RTK coverage extending up to 35 kilometers under ideal conditions, makes MBase the perfect base station receiver.

Longer Working Distance

Equipped the MeridianLink protocol internal radio and upper radio antenna port, Mbase offers up to 35km working range and increases flexibility. By eliminating the need for an external radio, the MBase becomes more lightweight, less complex, and more portable, which can lead to increased efficiency and convenience in the field.

Highly Integrated Four-in-one Antenna

The highly integrated four-in-one antenna on the MBase provides several advantages, including saving space, improving performance and reliability, and reducing the failure rate during use, making Mbase more portable and easier to handle, increasing the efficiency and accuracy of measurements.

Lightweight, Compact & Rugged Design

MBase is an ideal solution for surveyors who require portability and durability in demanding field conditions and eliminates the need for heavy external radio and accessories, ensuring easy transport and quick setup. This combination of lightweight portability, compact form factor, and rugged durability makes it a versatile tool for professionals on the go.

Enhanced Tilt IMU

Equipped with calibration-free IMU, support up to 60° tilt angle within 2cm accuracy, and no limitation tilt angle, allows for quick and accurate measurements without leveling the pole. Concentrate on where the pole tip needs to go, which is especially useful during a stakeout.
