Tallysman GNSS antenna for Reach M+
The Tallysman GNSS antenna for Reach M+ is a precision multi-band satellite positioning antenna engineered for high-accuracy real-time kinematic (RTK) and post-processing applications. Surveyors, drone operators, and geospatial professionals rely on this antenna to achieve centimeter-level positioning accuracy across GPS, GLONASS, Galileo, and BeiDou constellations. This antenna solves the critical challenge of achieving reliable satellite signal reception in challenging environments while maintaining compact form factor compatibility with the Reach M+ receiver.
Product Overview
The Tallysman GNSS antenna is a specialized multi-constellation receiver designed to work seamlessly with Emlid Reach M+ RTK receivers. It operates on the principle of phased array signal reception, capturing signals from multiple satellite systems simultaneously to enable rapid convergence and robust positioning solutions. The antenna features a low-noise amplifier (LNA) integrated into its housing, which amplifies weak satellite signals before transmission to the receiver unit. This design minimizes signal degradation over cable runs and ensures optimal signal-to-noise ratio even in urban canyon environments with partial sky visibility. The compact helical design provides excellent gain characteristics across all supported GNSS bands while maintaining a lightweight profile suitable for aerial and mobile platforms.
What distinguishes this antenna from standard GNSS receivers is its specialized tuning for the Reach M+ platform and its exceptional performance in multipath-rich environments. The antenna incorporates advanced filtering to reject ground reflections and interference from nearby RF sources, critical for achieving reliable RTK corrections in construction sites, urban areas, and near metallic structures. The integrated cable assembly connects directly to the Reach M+ via a standard SMA connector, eliminating compatibility issues and ensuring proper impedance matching. Its weather-sealed construction withstands extended field deployment across varying climatic conditions, making it suitable for long-term monitoring applications and mobile surveying operations.

How to Use
Begin by mounting the Tallysman GNSS antenna on a stable platform with clear sky visibility, ensuring the antenna's top surface faces upward with minimal obstruction from nearby structures, trees, or metallic objects that could cause multipath reflections. Connect the integrated SMA connector directly to the SMA port on your Emlid Reach M+ receiver, ensuring the connection is hand-tight and secure. For optimal performance, mount the antenna at least 30 centimeters away from other RF sources, power cables, and metallic surfaces that could degrade signal quality. Power on your Reach M+ receiver and configure it to receive RTK corrections from your chosen service provider (such as NTRIP caster or local base station). Allow the receiver 5-10 minutes for initial satellite acquisition and RTK convergence, during which the antenna will lock onto satellites from multiple constellations simultaneously.
For mobile applications such as UAV mounting, ensure the antenna is securely fastened to prevent vibration-induced connector loosening during flight operations. The integrated cable should be routed away from high-current power lines and motor controllers to minimize electromagnetic interference. In challenging urban environments with limited sky visibility, the antenna's multipath rejection circuitry will automatically filter spurious signals, though positioning accuracy may degrade slightly compared to open-sky conditions. Periodically inspect the antenna housing and connector for water ingress or corrosion, particularly after extended field deployment in wet conditions. The IP67 rating ensures water resistance, but avoid submerging the antenna or exposing the connector to standing water for extended periods.
Frequently Asked Questions
What is the difference between L1, L2, and L5 frequency bands in GNSS reception?
L1 (1575.42 MHz) is the primary civilian GPS frequency and is supported by all satellite systems. L2 (1227.60 MHz) provides additional signal diversity and enables dual-frequency ionospheric error correction, significantly improving accuracy in challenging environments. L5 (1176.45 MHz) is a newer frequency with superior signal strength and better multipath rejection characteristics. The Tallysman antenna receives all three bands simultaneously, enabling rapid RTK convergence and superior accuracy by leveraging redundant satellite signals across multiple frequencies.
How does RTK (Real-Time Kinematic) positioning work with this antenna?
RTK positioning requires the Reach M+ receiver to receive real-time correction data from a reference base station operating at a known location. The Tallysman antenna captures raw satellite signals, which the receiver processes along with correction data to calculate your precise position with centimeter-level accuracy. The multi-constellation support of this antenna ensures sufficient satellite visibility for rapid convergence to fixed integer ambiguity solutions, typically achieved within 30 seconds to 2 minutes depending on environmental conditions. Without RTK corrections, standalone positioning accuracy is typically 2-5 meters; with RTK, accuracy improves to 2-3 centimeters horizontally and 3-5 centimeters vertically.
Can this antenna be used in areas with poor satellite visibility such as forests or urban canyons?
While the Tallysman antenna's multipath rejection and integrated LNA provide superior performance compared to standard antennas, positioning accuracy will degrade in areas with severely limited sky visibility. Forests with dense canopy cover and deep urban canyons surrounded by tall buildings will reduce the number of visible satellites and increase multipath errors. In such environments, positioning convergence time may increase from seconds to minutes, and accuracy may degrade to decimeter-level rather than centimeter-level. For optimal performance, ensure at least 30-40 degrees of unobstructed sky visibility above the antenna horizon. Using a mobile platform that moves through the area can improve satellite geometry and convergence speed.
What is multipath rejection and why is it important?
Multipath occurs when satellite signals reflect off nearby surfaces (buildings, water, metal structures) before reaching the antenna, creating delayed copies of the direct signal. These reflected signals degrade positioning accuracy by introducing errors in distance calculations. The Tallysman antenna incorporates specialized filtering and helical design that preferentially receives direct signals while rejecting reflected signals. This multipath rejection capability is critical for maintaining centimeter-level accuracy in urban and industrial environments where reflective surfaces are abundant. Without effective multipath rejection, positioning errors can exceed 10-20 centimeters in such environments.
