New GNSS correction service launched for Australia

June 17, 2020  - By

logoAustralia-based Position Partners has launched MiRTK, an open architecture corrections service for GNSS equipment.

Internet-enabled, MiRTK offers an alternative to UHF radio correction services for high-accuracy GNSS. 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.

MiRTK uses a small modem that slides onto the accessory slot of the tripod and connects to the base station via a single cable.

A subscription service is available in locations with the Telstra network, mainly continental Australia.

MiRTK is designed for accurate GNSS positioning in the construction, mining and geospatial industries. It is compatible with all brands and models of GNSS 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,” said Cameron Waters, geospatial business manager at Position Partners.

“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.

Another benefit, according to Waters, is the ability to utilise a single correction protocol across all GNSS equipment on site. This dramatically reduces 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 utilize 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, with unlimited potential to scale up connections as required.

“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, whilst utilizing their existing GNSS hardware.”
