Geometer International debuts lightweight, compact RTK device - GPS World - GPS World magazine

Geometer International, a Ukrainian developer of GNSS/RTK instruments and applications for outer positioning, has introduced the Walker RTK, a dual-frequency L1, L2 RTK receiver successful the compact signifier origin of a portable RTK device.

The Walker RTK is simply a lightweight, small-sized, affordable and full-featured instrumentality for collecting, storing and processing geo-referenced information connected the survey site. According to the developer, a GNSS receiver successful a convenient and affordable format volition importantly grow the usage of RTK technology. The caller exertion volition beryllium suited to astir tasks requiring centimeter precision positioning and measurements successful a 3D coordinate system.

Compact and lightweight, Walker RTK is the perfect solution for tract workers moving distant from the office. The caller instrumentality tin beryllium operated with conscionable 1 hand, importantly improving the productivity of work personnel.

Possible applications for GNSS Walker RTK see surveying, utilities, star powerfulness works engineering, trenching and pipeline installation, drilling, forestry and municipal infrastructure control.

What’s nether the bonnet of Walker RTK?

The Walker RTK is built astir a 2-frequency L1/L2 184 transmission committee and a delicate Helix antenna, satisfying up to 90% of basal idiosyncratic requirements. The tube-shaped lodging geometry allows it to acceptable with immoderate cosmopolitan mount. The receiver value is lone 0.25g (0.470 with smartphone holder) owed to the aluminum alloy lodging with a protective coating. The Walker RTK has a built-in Li-Ion artillery with capable powerfulness for 24 hours of continuous cognition without further recharging. The caller energy-efficient architecture of the portion achieves this.

The GNSS receiver has the minimum magnitude of starring interfaces, resulting successful precocious IP67 particulate and waterproof rating. The instrumentality tin beryllium paired with a smartphone oregon tablet via Bluetooth, portion transportation via BLE is besides planned for a aboriginal release.

Compatible with outer systems

Walker RTK tin way and find geo-position utilizing signals from each known existing outer systems. This diagnostic makes it imaginable to execute the centimeter-level accuracy of an RTK solution wrong seconds.

GNSS signals processed by the Walker RTK GNSS receiver:

• GPS (L1C/A, L2C)
• GLONASS (L1OF, L2OF)
• GALILEO (E1B/C, E5b)
• BEIDOU (B1I, B2I)
• QZSS (L1C/A, L1S, L2C)
• SBAS (L1C/A)

Thanks to NMEA messaging, the Walker RTK GNSS receiver is afloat compatible with immoderate nonrecreational oregon freeware geolocation software, providing precocious accuracy and reliable RTK-corrected positioning.
