The Robot Plotter is a compact, fully autonomous, self-driving robot that uses RTK-GNSS positioning to place lines and other markings on a variety of ground surfaces. The machine, made by Netherlands-based Tyker Automation, sets out markings 12 to 16 times faster than traditional three- or four-person crews.

In the wake of the latest COP session on international climate change, and as the world continues to deal with the effects of a warming planet, researchers say more and better data can help ameliorate the damage and provide answers on how to respond to it.

The industry is innovating in GNSS, IMU and HD mapping technology, but more work is needed to develop higher performance, lower cost applications that enable instant, extremely accurate positioning at the centimeter level or better for lane-level navigation.

A: Many forms of differential GNSS (DGNSS) exist to provide GNSS users with corrections to their pseudorange and carrier-phase measurements along with information to support their applications and provide integrity assurance [1].

In this column, guest contributor Mike Horton from ANELLO Photonics introduces a new gyro technology that bridges the market gap between high-performance (but expensive) sensors (fiber-optic and ring laser gyros) and low-cost (but imprecise) MEMS gyros. Benefits of improved gyro quality enabled by SIPHOG are illustrated, including GNSS-denied navigation scenarios.

While an independent report from NASEM has validated some NTIA GPS interference claims, no real mitigation is in in sight.

Keysight Technologies recently became the first to receive Global Certification Forum (GCF) validation of a 5G location based services (LBS) Assisted Galileo (A-Galileo) test case by combining 5G new radio (NR) and GNSS technology—an achievement that will accelerate the implementation of LBS in smartphones.

Through its recent acquisition of IoT firm Nestwave, NextNav can now combine its highly synchronized TerraPoiNT GPS backup system with Nestwave’s existing terrestrial LTE/5G signals to create near nationwide resilient PNT capabilities—lowering deployment costs by an estimated 75%, or more than $250 million, and allowing the company to scale sooner.

Oxford Technical Solutions Ltd (OxTS) is an established supplier of inertial navigation systems (INS), particularly to the automotive industry. Since 1998, its products have been providing critical data about where a vehicle is, how it’s oriented and how it’s moving. More recently the company has been making a big splash in the airborne mapping sector.

After years of studying the concept of using low-Earth orbit (LEO) navigation satellites to supplement the Galileo system, the European Space Agency (ESA) is ready to move forward with an in-orbit demonstration as part of its new FutureNAV program.
