The TW5000 series Tracking receiver/antennas are designed to deliver superior geo-positioning performance, with multi-constellation, dual feed capability and industry leading multi-path rejection. For use with any telematics or inertial system, connected via RS-232 or RS-422.
Tallysman’s Augmented Smart Antenna/Receivers utilize Multi-Constellation/Full Band Accutenna Dual Feed patches, combined with PPP-RTK augmentation services (IP Network delivered, L-Band or both) or RTK in Base/Rover configurations to deliver <20 cm accuracy (PPP-RTK) (with <40 second convergence) or <10 cm accuracy (RTK Base/Rover).
In Base/Rover configuration, Tallysman’s Augmented Smart Antennas can deliver high precision heading.
For automated driving, drones and other applications that require high precision.
Note. These antennas also have excellent performance without augmentation, due to their Multi-Band antennas.

We make it easy for you to try out our Ultra-Precise Augmentation Smart Antenna/Receivers AND the services they are designed to use.
Tallysman’s PPP and PPP-RTK capable Augmented Smart Antenna/Receivers utilize the u-blox F9x series of GNSS receivers, and the DSx series satellite based GNSS correction receivers. Â As a u-blox design partner, Tallysman and u-blox collaborate to ensure Tallysman Smart Antennas are designed and manufactured to the highest-standards. They are immediately usable out of the box with the excellent accuracy you can derive from non-augmentation, using a great antenna and receiver ( <50cm accuracy) (see GNSS Positioning Techniques), but there is so much more when using augmentation, and we help you get there with our Software Development Kits (SDK).
With our SDK, we make it easy to go further and test out PPP and PPP-RTK correction/augmentation performance. Â First, you can easily connect Tallysman Smart Antennas with RS-485 interfaces to a PC by using the USB converter included in the SDK and the TruPrecision application for easy configuration. Â
TruPrecision software makes it easy to test Base/Rover configuration (RTK) performance by providing easy to use configuration options such as Base Survey-In optimization parameters (accuracy vs. survey-in time objectives), and for non-adjacent Base/Rover pairs, Â instantly configurable internet-based channels for broadcasting RTCM connections from an SDK configured as a Base to multiple SDKs configured as Rovers. Â Next, Tallysman and u-blox collaboration allows PPP Augmentation to be easily tested, because with every SDK there is a 60 day free subscription to u-blox’ PointPerfect Augmentation Service.
The Quick-Start guide included in the kit shows you how to  use the redemption code, load the encryption keys into TruPrecision, and start using PPP-RTK corrections. Â
TruPrecision also gives you an extremely useful hybrid solution for taking advantage of RTK’s excellent accuracy (<1 cm) without the pain of the long Base Survey-In times by using PointPerfect to do a “Fast Survey-in” of the Base, then turn off the PPP-RTK correction service (PointPerfect) for the Base automatically once Surveyed-In. Â Historically Survey-In of a Base can take 24 hours. Â Fast Survey-in using PPP-RTK augmentation services (PointPerfect) can be <20 minutes or even better, depending on accuracy vs survey-in goals!
 Finally … there is one more thing.  Base/Rover RTK configurations allow for Precision Heading, which are extremely useful for autonomous operation. Once again, TruPrecision and the SDK make this easy to use and test.
To test PPP-RTK functionality (PointPerfect) over L-Band and IP-networks, the 33-TP5390SDK-0 is required. Â To test Base/Rover configurations and Precision Heading, then a 33-TP5384SDK-0 is needed for the Base. Â The Rover can be a 33-TP5384SDK-0 or a 33-TP5390SDK-0. Â Of course, if you don’t need the PC test set up, and you want to jump right into solution integration, you can just use the antennas – TW5384 for a base or rover, and TW5390 (IP-Network, IMU, L-Band, RS-485), or TW5790 (IP-Network, IMU, L-Band, Type A USB), or TW5390C (IP-Network, IMU, QZSS CLAS signalling over L6, RS-485) or TW5386 (IP-Network, IMU, RS-485) for Rovers. Colocated Base/Rover operation with dedicated RTCM Corrections port between antennas requires RS-232 interface version of TW5384/86.Â
TP5390SDK Unboxing
In this age of digital design, the connection between the GNSS antenna and GNSS receiver is a gaping exposure to systemic error that should not be trivialized. Â To get a full appreciation for the issues we highly recommend taking some timeout to enjoy the GNSS webinar (linked to the image at the left).
The job of a GNSS antenna is to present as clean a signal to the receiver as possible. Â The antenna cleans that up as best as it can (taking care of the big items, such as multi-path interference, satellite azimuth and elevation, in-band interference, phase-centre error etc.), but the path from the physical antenna element to the Receiver leaves a lot of room for further systemic errors into the signal reception, especially using the traditional approach of locating the antenna some distance from the receiver, exposed to local system impairments.
The shift to a carrier phase precise positioning solution with integrated L-Band augmentation imposes a new level of detail in GNSS system design.
Receiving and preserving the quality of the GNSS signal from the antenna element to the receiver is essential to persisting carrier phase lock, avoiding cycle slips, and maintaining convergence while operating in challenging environments.Â
As a low amplitude, easily impaired signal, the best way to do that is to design around a known (to the best of ability to know) physical  and electrical set of parameters.
Simply put, reducing the window for fault injection by constraining the variables between analog GNSS signal and digital representation of the geo-location information, to a known set, is the optimal path. Â Tallysman does that by integrating our best antennas with the best commercial receivers in the native antenna mechanical package, presenting the GNSS receiver to the target system over a suitable “fit for purpose” interface, such as:Â
- RS422/485
- RS232
- USB2.0 Type A
- USB2.0 Type A, BLE, WiFi
- CANBus
- Automotive Ethernet 100BaseT1
