Taoglas Introduces Active Multiband GNSS Antennas for High-Accuracy Positioning and Timing

Taoglas, a global leader of advanced antenna designs, unveiled its new active, multiband GNSS antennas – the MagmaX2 AA.200 and Colosseum X XAHP.50 engineered for use in applications that require critical high-accuracy positioning and timing applications, including autonomous driving and precision agriculture applications. These two new antennas add to Taoglas’ already unrivaled, high-precision GNSS range and bolster the most comprehensive portfolio of high-precision GNSS antennas in the market today. With over 16 years of expertise with GNSS antenna products, Taoglas helps enterprises deliver industry-leading positioning and timing solutions.

Safety standards for autonomous vehicles (UAVs, robotics, and vehicles) and precision agriculture is an ever-evolving arena, however, it’s increasingly apparent that high-precision positional accuracy is critical for both. At Taoglas they’re continuously innovating GNSS antennas to deliver the very best precise location capabilities but are more lightweight, compact structures, compared to larger counterparts already on the market. The MagmaX2 AA.200 is the best solution for where space and weight constraints are at a premium, such as with a robotic lawnmower. 

The Colosseum X XAHP.50 geodetic quality small dome antennas are more suitable for a roof vehicle mount, or pole mount. Every element and aspect of the antenna performance has been optimized during the design of this antenna. This includes many deep interlocking rf parameters for true accurate centimeter-level positioning, compared to legacy meter only level systems. Phase center variation, group delay, multipath rejection, an axial ratio over angle all become critical considerations and performance targets.

In the design phase, they simulate using Electromagnetic analysis software and tweak every parameter. Once we are happy with the results we build our prototypes and test in scientifically controlled chamber and test environments validated by the European Space Agency, with repeatable GNSS signals. We then move onto field testing in open sky conditions and in non-line of sight environments to verify real-world performance with today’s state of the art receiver systems from such leading companies as u-Blox and Septentrio

Multipath error is a critical, unavoidable source of error in GNSS receivers. It’s the combination of direct and indirect signals reflected off nearby obstacles (buildings, vehicles, people, etc.) one or more times, before reaching the GNSS antenna. The indirect, multipath signals distort the received signal used for acquisition and tracking. Taoglas has designed lightweight, cost-sensitive compact antennas that can obtain similar levels of multipath rejection compared to conventional large and expensive geodetic antennas.
