Tallysman Wireless

What Tallysman Wireless does

Tallysman Wireless, founded in 2009 in Ottawa, Canada, designs and manufactures high-precision GNSS and Iridium antennas for satellite-based positioning and navigation applications. It is now a wholly-owned brand and operating unit of Calian Ltd. (TSX: CG), reported through Calian's Advanced Technologies / Space GNSS division. The product portfolio is anchored on four proprietary antenna technologies — patented Accutenna® (multi-path rejection, single/dual patch, 80 MHz truly circular response), patented VeraPhase® (lowest axial ratios horizon-to-horizon, ±1mm phase centre variation), VeroStar™ (IP69K, low-elevation tracking), and Helical™ (4–42 g quadrifilar helix for UAVs and drones) — supplemented by smart antenna-receiver modules integrating these antennas with third-party receiver platforms (u-blox, STMicroelectronics, Septentrio), anti-jamming antenna technology, custom RF engineering services, and a self-serve antenna selection tool.

Tallysman produces from a 65,000-sq-ft high-precision manufacturing facility in Ottawa and supports all major satellite constellations (GPS, GLONASS, Galileo, BeiDou, QZSS, NAVIC, Iridium) plus L-Band correction services for RTK and PPP applications. Target use cases span survey and mapping (primary), marine, aviation, agriculture, UAV/drone/robotics, and machine control. The company sells primarily through Calian's global Precision Partner Program (deal registration, marketing development credits, partner portal, annual partner conference) with direct field sales support for custom enterprise engagements. Pricing is quote-based and not publicly disclosed. The most prominent disclosed end customer relationship is a 12+ year engagement with Sampson Technology Ltd. for Galileo HAS testing via the LabSat product line.

Core offering

Tallysman Wireless develops and manufactures high-precision GNSS (Global Navigation Satellite System) and Iridium antennas, including smart antenna-receivers and anti-jamming technology. The company produces proprietary antenna technologies — Accutenna, VeraPhase, VeroStar, and Helical — that support satellite-based positioning and navigation applications such as surveying, marine, aviation, agriculture, and UAV/drone platforms. It also offers custom antenna and RF engineering services and plug-and-play software development kits.

Product overview

Tallysman Wireless, now part of Calian's Advanced Technologies division, offers a portfolio of high-precision GNSS (Global Navigation Satellite System) antennas and related technologies. The product lineup centers on four core antenna technologies—Accutenna™ (patented multi-path rejection), Helical™ (lightweight for UAVs/drones), VeroStar™ (high-demand applications), and VeraPhase™ (premium performance)—which serve as the foundational antenna elements across the portfolio. These are complemented by Smart Antenna-Receivers that integrate Tallysman antennas with third-party GNSS receiver platforms (u-blox, Septentrio, ST), and Anti-Jamming Technology for signal protection. The portfolio supports GPS, GLONASS, Galileo, BeiDou, QZSS, NAVIC, and Iridium constellations plus L-Band correction services for RTK and PPP applications. Custom engineering services and an antenna selection tool support specialized deployments.

Broad incumbents

• Trimble: Trimble is a large incumbent in positioning technology offering GNSS antennas, receivers, and full survey/construction/precision-agriculture solutions. Trimble Zephyr and other antenna products compete with Tallysman in survey and reference station applications, while Trimble's broader portfolio extends far beyond antennas.
• u-blox: u-blox is a major GNSS receiver/chip manufacturer (ZED-F9P, NEO-M9N) and a current integration partner of Tallysman. It is a broad incumbent in positioning chipsets that overlap with Tallysman's smart antenna-receiver modules and competes in some end-segments, though u-blox does not produce standalone high-precision GNSS antennas.
• Topcon Positioning: Topcon offers high-precision GNSS antennas, receivers, and integrated solutions for survey, construction, and precision agriculture. Broad incumbent comparable to Trimble that overlaps with Tallysman's antenna business in OEM survey and machine control channels.
• Taoglas: Taoglas designs and manufactures a broad portfolio of antennas and RF components including GNSS antennas for IoT, automotive, and industrial markets. While broader than Tallysman's positioning focus, it overlaps in active GNSS antennas and embedded GNSS modules.

Emerging players
