Pix4D Inc. (Shibuya-ku, Tokyo, hereinafter "PIX4D"), as the sole domestic distributor for Emlid Tech Kft. (Headquarters: Budapest, Hungary, hereinafter "Emlid"), introduces new standards to the Japanese surveying market.
Emlid's flagship model, the "Reach RS3," has now been registered as a Class 1 GNSS surveying instrument by the Geospatial Information Authority of Japan (GSI). Concurrently, PIX4D is expanding its product lineup with the introduction of the cutting-edge "Reach RS4 Pro," a flagship model supporting visual surveying, and the "Reach RX2," a compact and lightweight device featuring multi-frequency and tilt compensation capabilities. Under Emlid's philosophy of "high precision for everyone," PIX4D combines overwhelming cost performance with reliability to accelerate DX in Japan's surveying and construction fields.
■ Reach RS3: A New Standard for Public Surveying
Trust to support professional sites with "Class 1 GNSS Surveying Instrument" registration.
The "Reach RS3" has completed its registration as a "Class 1 GNSS Surveying Instrument (Registration No.: 259)" with the Geospatial Information Authority of Japan. This officially allows its use in public surveying operations.
Multi-functional Correction Communication: Supports both base and rover stations. In addition to network RTK, it supports LoRa communication for both transmission and reception, flexibly adapting to various field environments.
Tilt Compensation Function: Equipped with IMU-based tilt compensation that requires no calibration. It maintains high-precision positioning even at inclinations of up to 60 degrees, enabling rapid observations in places where it is difficult to hold a pole vertically.
NTRIP Caster Function: The "Reach RS3" can serve as a base station to distribute correction information via the internet, allowing devices other than Emlid products, such as drones, to be used as rovers.
Furthermore, in situations where establishing an internet environment is challenging, the "Reach RS3" can act as a hotspot to distribute correction information via Wi-Fi.
Mobile Operation: With the dedicated app "Emlid Flow," settings and observations can be completed using just one smartphone (iOS and Android compatible), realizing intuitive operability.
■ Reach RS4 Pro: The Power of "Vision" to Overturn GNSS Surveying Norms
A Flagship Model Integrating Visual Positioning and Multi-frequency Reception
The "Reach RS4 Pro," a higher-end model than the "Reach RS3," dramatically improves work efficiency through multi-frequency support and the inclusion of dual cameras.
Visual AR Function with Dual Cameras: Equipped with Full HD cameras that capture forward and directly downward. It offers intuitive stakeout utilizing AR (Augmented Reality) and an innovative workflow for acquiring coordinates from photos of inaccessible locations.
Multi-frequency/Multi-satellite Support: Already compatible with L1/L2/L5. Future compatibility with L6 (QZSS/CLAS) is also planned. This achieves faster and more stable fixes even in harsh environments with many obstructions.
UHF Transmission Support: Evolving from the "Reach RS3," which only supported reception, the "Reach RS4 Pro" can now transmit UHF correction information (base station operation). This expands its range of applications, transforming it into a more versatile GNSS instrument.
Quick Release (Optional Accessory): Adopts a quick-release mechanism for one-touch attachment and detachment to poles, etc. This makes the installation and removal of the receiver safer and faster. If not using the quick release, attachment/detachment via a 5/8-inch threaded connection is also possible.
The "Reach RS4 Pro" aims for further expansion of its application scenarios and is scheduled to apply for GSI Class 1 GNSS surveying instrument registration around Spring 2026. This unit represents an extremely strategic investment value, anticipating its use in public surveying.
■ Reach RX2: A Palm-Sized, Powerful New Generation Device
IMU-based tilt compensation and multi-frequency support in your hands. Weighing only 280g, it's astonishingly lightweight, lighter than a 350ml can of juice.
Even when combined with Emlid's genuine telescopic pole, the total weight is only 1.2kg, achieving overwhelming lightness that reduces the burden of work.
The "Reach RX2" evolves the user-friendliness of the "Reach RX" into professional specifications. It is a network RTK dedicated receiver for professionals who prioritize mobility.
Evolution to Multi-frequency Support: A significant upgrade from the previous model (Reach RX)'s two frequencies to L1/L2/L5 multi-frequency support. This improves performance in urban areas and mountainous regions. Furthermore, future compatibility with L6 (QZSS/CLAS) is also planned.
Addition of Tilt Compensation: The long-awaited IMU-based tilt compensation, requiring no calibration, has been newly incorporated. It supports inclinations of up to 60 degrees, allowing observations without holding the pole vertically.
