For GNSS applications, an omnidirectional antenna known as a choke ring antenna is employed. Its structure consists of a core antenna element surrounded by a number of concentric conducting rings. These antennas have a reputation for being able to block multipath signals, which are reflections of satellite signals from adjacent objects.
This comprises signals reflected off of objects, topography, plants, buildings, and other surfaces like the ground and water. In order to decrease multipath transmissions in both the L1 and L2 bands within the same antenna configuration, choke ring antennas contain specifically designed filters put in each groove.
The Global GNSS Choke Ring Antenna market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
With the launch of a high accuracy choke ring antenna, Tallysmanâa pioneer in the production of high performance GNSS antennas and associated componentsâexpands its already extensive offering. Tallysman's VeraChoke provides a choice in form-factor for reference and monitoring applications and delivers the best performance of any choke ring antenna on the market by adapting existing advancements that fuel its revolutionary VeraPhase antenna.
The initial version of the VeraChoke antenna, the VC6100, and its sibling, VeraPhase®, both use high efficiency elements that are similar in design. However, the rings have been made slightly pyramidal with the choke-style form-factor to improve reception of low elevation satellites.
They have also been optimised for all GNSS signals.The VC6100 choke ring antenna is unique in a new accuracy class, with the narrowest Phase Centre Variation (PCV) of no more than 1mm for every frequency.
The VC6100 has an extremely low axial ratio and can receive all GNSS signals. The VC6100 is a high performance antenna by Tallysman that, like other of their high performance antennas, is reasonably priced to help enhance antenna density for reference installations, CORS networks, and monitoring applications. Both big and little SCIGN radomes can be supported by the antenna.
