GNSS and Precision Farming

Dr. John Fulton, Ohio State University

Nowhere has the fact that GNSS can guide things besides military weapons and transport manifested itself more profoundly than in agriculture.

While Google and automotive manufacturers struggle to figure out how to put autonomous vehicles on the highway, farmers have been using GNSS for well over a decade to guide equipment through their fields — along with a host of other ag-related, site-specific applications.

Indeed, GNSS — along with an array of other high-tech resources — is transforming agriculture at an accelerating rate.

Trimble Launches Timing Portfolio for Mobile Telecom

ICM SMT 360 timing module

Trimble has introduced a new portfolio of GNSS-based time and frequency products to address the synchronization needs of the fast-growing 4G LTE (Long Term Evolution) small-cell telecom market.

Mobile telecom networks, whether 3G, 4G LTE, LTE-Advanced (LTE-A) wireless technologies, or a combination, need high-precision synchronization and syntonization.

What are the actual performances of GNSS positioning using smartphone technology?

Tables 1, 2, 3 & 4

Q: What are the actual performances of GNSS positioning using smartphone technology?

A: “Where I am?” is the typical question asked by a person when visiting a new city or unknown place. Knowing one’s own location is generally a basic necessity for people, both in indoors and outdoors.

Multi-GNSS Precise Positioning

Dennis Odijk, Curtin University

The availability of carrier phase tracking — counting the cycles of GNSS signals between satellites and a receiver — has long enabled high-precision users to achieve greater accuracy than using the navigation messages or pseudoranges. Improvements in high-end receivers and techniques such as real-time kinematic (RTK) and precise point positioning (PPP) have made once inconceivably accurate results almost routinely accessible.

Kingfisher

Eugenia Acosta, an intern with Clearpath Robotics, unloads a Kingfisher unmanned vessel in preparation for a mission (top photo), the Kingfisher components and controller (bottom photo).

“Our products are robotic research platforms,” says Clearpath’s Meghan Hennessey. “These can be configured and programmed so that our customers can explore their particular areas of interest without all the cost and troubleshooting involved in actually building robots themselves.”

Hennessey says Clearpath platforms — which include the all-terrain Husky, the larger, tractor-like Grizzly and the waterborne Kingfisher — can be thought of as project kits.
