ComNav launches Mercury Laser RTK surveying device

To address one of field surveying's most persistent frustrations – the dependence on poles and data collectors – ComNav Technology has introduced the Mercury Laser RTK handheld GNSS measurement device. The product is the latest addition to the company's SinoGNSS Universal Series.

The device brings together GNSS positioning, laser measurement and inertial measurement unit (IMU) technology on a single platform, built around ComNav's new K9 chip architecture. Its laser range extends to 50 metres, and an integrated long-focus camera supports remote operation. Connectivity options include Wi-Fi, Bluetooth and 4G.

At approximately 500g and small enough to fit in a vehicle cup holder or a jacket pocket, the Mercury is a notably compact instrument for surveying grade work.

Four operating modes

The Auto-IMU function initializes during movement, removing the need for a stationary calibration step, while a quick capture button and automatic image recording with coordinate logging keep data collection efficient in the field. A real-time laser visualization feature displays measurement points directly on screen, helping operators confirm positions and locate targets without the back and forth of traditional setups.

ComNav's new device supports four operating modes, from conventional pole and data collector use through to fully independent handheld operation. A radio mode for offline environments is listed as a forthcoming update. Underpinning the hardware is a surveying-grade antenna for satellite signal capture, which ComNav says delivers stable performance across varied terrain and environmental conditions.

The Mercury is aimed squarely at surveyors working in constrained or hard-to-access sites, such as urban construction zones or locations where setting up a traditional pole is simply not an option.
