Position Partners launches MiRTK for high accuracy GNSS


An internet-enabled correction service that offers an alternative to UHF radio correction services is being used for accurate GNSS positioning in the construction, mining and geospatial industries.

Intelligent positioning solutions provider Position Partners has announced its MiRTK service for GNSS equipment, which can utilise the internet instead of UHF radio frequencies. MiRTK is compatible with GNSS brands and models from manufacturers including Topcon, Trimble, Leica Geosystems, Sokkia, Hemisphere and more.

“Until now, users that rely on high precision GNSS for applications such as surveying and machine control had no option but to use UHF radios or a network RTK solution,” Position Partners geospatial business manager Cameron Waters said.

“Anyone that’s had to rely on UHF radio frequencies will have experienced problems, including interference, range limitations, costly licensing and severe penalties for breaching licensing laws. MiRTK offers an alternative that is refreshingly simple: no repeaters, no line of sight issues and no complex licensing,” he added.

Designed for the geospatial, construction and mining sectors, MiRTK works with GNSS equipment, using a small modem that slides into the accessory slot of the tripod and connects to the base station via a single cable.

Unlike UHF radios, MiRTK is not limited by range from the GNSS base station and does not require line of sight with the survey rover or machine. It only requires a cellular internet connection.

Waters said another benefit of MiRTK is the ability to utilise a single correction protocol across all brands and types of GNSS equipment on site, dramatically reducing complexity and potential connectivity issues.

“MiRTK uses NTRIP and a user selectable format such as RTCM3 or CMR that can be used universally, regardless of the brand or model of equipment,” he said. “Users enjoy full speed, full constellation connectivity without the complex radio settings, baud rates, bandwidth or scrambling problems that you get when trying to utilise different GNSS systems with UHF radios.”

To set up the unit, users simply connect the modem to the base station, power the modem on and MiRTK will work for up to 20 hours continuously without charge. Each unit can connect with up to 10 devices such as survey rovers or machine systems as standard.

MiRTK offers the first Hardware as a Service (HaaS) for the geospatial sector, covering the hardware, data and warranty in either a 12-month or 24-month subscription.

“The future of UHF is limited with lower bandwidth, higher density areas, increased governance, rising costs and little flexibility,” Waters said. “MiRTK gives customers a new approach to receive reliable correction data in a simple and hassle-free way, while utilising their existing GNSS hardware.”
