Breaking Down Borders

Challenge The team discovered Mwendo, a community of 3,000 people. To access water, residents had to carry 20-litre jerry cans. The plan to rehabilitate a large water tank and install a pipe direct to the local school faced challenges—due to their use of a gravity-fed system. The elevation change and the difficulty of the terrain …

Improving productivity on a no-till farm with Trimble RTX positioning services

Challenge Although the Zunckels had successfully farmed using no-till practices for many years, performing field operations without a high-accuracy GNSS solution impacted their potential yields. Tyson Zunckel began searching for a GNSS correction service to increase the accuracy of their precision agriculture guidance equipment about nine years ago. He ruled out the option of building …

Precise GNSS helps researchers understand the behavior of active volcanoes.

Challenge Measuring vertical gradients of gravity on the slopes of Mount Etna helps forecast volcanic hazards. While Mount Etna is surrounded by geodetic control points, conducting real-time GNSS observations was challenging. Inconsistent cellular service made a connection to Italy’s real-time GNSS network difficult and constraints on radio licensing ruled out conventional RTK. Approach To ensure …

Surveyors Achieve Productivity and Accuracy Remotely with Trimble RTX

Challenge Cape Survey Ltd. was selected to determine the location for 61 large wind turbines, capable of powering 120,000 homes. While the site provided excellent conditions for GNSS, its remote location made it difficult to achieve the required accuracy and ties to South Africa’s reference system. There was no connection to cellular service, and the …

High-Accuracy Correction Service at Work on Alabama Farms

Challenge Mike Lawrence farms 1,800 acres of corn and soybeans along the Black Warrior River, outside Greensboro, Alabama. Because of the farm’s relatively isolated setting, GNSS correction services options are limited. The previous owner had built a base station that Lawrence considered for use in constructing his own RTK network, but the hassle of setting …

Accuracy and Efficiency in Remote Locations

Challenge Surveyors using GNSS in South Australia face challenging conditions, working across vast terrain without the investment or population distribution to support a statewide real-time network. As a result, surveyors in outlying areas must rely on static techniques to establish local control. They can then use single-base RTK for specific project operations, while multiple RTK …
