Tallymatics has introduced the TW5390 smart antenna with IP network and L-band augmentation service capability.
Tallymatics is a division Tallysman Wireless, a Calian company, specializing in of precision geolocation applications and equipment.
To create the TW5390, Tallymatics leveraged its experience in GNSS applications, design and manufacturing, combining Tallysman’s GNSS antenna technology with the high-precision u-blox F9R GNSS receiver and DS9 L-Band receiver modules.
The combination delivers a reliable and convenient smart antenna yielding <6 cm accuracy, with precise point positioning/real-time kinematic (PPP/RTK) augmentation services via the PointPerfect subscription service.
The TW5390 solves the complexities of GNSS design — it sends the host system PPP/RTK corrected coordinates in NMEA format over a robust RS-485 interface, assuring results that meet customers’ high expectations.
Features of the TW5390
- simultaneous dual-band coverage for GPS, Galileo, GLONASS and BeiDou
- superior multipath rejection with Tallysman Accutenna technology
- low noise amplifier
- Tallysman’s eXtended Filtering (XF) technology, which mitigates saturation from nearby RF signals (targeting
- LTE and Ligado)
- tight, measured phase-center offset and low axial ratio, enabling accurate and precise positioning
- direct decoding of PointPerfect, SPARTN formatted augmentation packets (u-blox specific)
- IP network and L-band augmentation communications channels
- built-in inertial measurement unit for UDR and ADR
- fast convergence time of 40 seconds (PPP/RTK) with < 6 cm accuracy
- IP69K package
- RS-485 transceivers
- Tallymatics SDK available with computer interface, TruPrecision software and 60 days of free PointPerfect
- service
- cable lengths of 5, 15 and 25 meters
- rugged, fixed mount
