When it comes to high-precision applications, the need for accuracy and reliability is paramount.
From navigating under a forest canopy to tracking assets in crowded cityscapes, Calian GNSS antennas (formerly Tallysman) are engineered to deliver precise positioning even in the most challenging environments. Here’s how our advanced GNSS antenna technology enhances performance and minimizes common issues like radio frequency interference, multipath effects and partially obstructed sky view.
The challenge: Maintaining accuracy under interference
Mitigating multipath effects
One of the standout features of Calian GNSS antennas is their advanced multipath rejection capabilities. Multipath occurs when GNSS signals reflect off surfaces like buildings or roads before reaching the antenna, creating a delayed and polarization flipped signal that distorts positioning accuracy. Calian’s antenna designs utilize multi-feed technology to minimize the effects of the reflections that can affect accurate, real-time positioning.
Enhanced signal reception in harsh conditions
In dense forests, GNSS signals can be obstructed by heavy foliage, while in urban environments, tall buildings can cause frequent signal loss. Calian GNSS antennas are equipped with high-gain, multi-constellation and multi-frequency designs, which enable robust signal reception even in low-visibility conditions. By capturing more of the satellite signals, our antennas provide data continuity when other antennas might lose lock.

Durability to withstand tough environments
Our antennas are designed to withstand the elements, from extreme temperatures to heavy rain and other environmental factors. This durability ensures they keep performing, regardless of the conditions, providing a resilient, consistent solution for industries where signal availability and PNT accuracy is essential.
