Precise GNSS positioning is a key issues in the development of GNSS receivers. Improve the efficiency positioning of your GNSS receiver with the accurate, reliable and robust Tallysman’s TW3972 antenna.
Tallysman’s TW3972 is a multi-signal and multi-band antenna which is capable to receive triple band GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2, Galileo E1/E5a+b, NavIC L5, SBAS available in the region of operation (WAAS, EGNOS, MSAS, GAGAN) as well L-band correction services coverage. This is an optimal, compact and versatile antenna that is specifically designed for precision triple frequency positioning.
The TW3972 covers a variety of application areas such as precision agriculture, autonomous vehicle tracking and guidance, and other areas where precision matters. Tallysman’s antenna solutions have operational benefits for the railroad industry.
The TW3972 antenna provides superior multipath signal rejection, a linear phase response and tight phase center variation (PCV). The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wide-band LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output. Besides, the antenna also has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands which is common in challenging urban environments.
The TW3972 provides an excellent axial ratio and a tightly grouped phase center variation that produces clean code and phase measurements. This makes Tallysman’s TW3972 the ideal antenna solution for high-precision applications, such as Real Time Kinematic (RTK) or Precise Point Positioning (PPP).
Thanks to the through-hole weatherproof enclosure, the TW3972 ideal for permanent installation.
The TW3972 antenna is provided the 100mm ground plane. This is recommended for non-roof-top installations.
