Base Stations and Receivers

Topcon offers the accuracy solutions to do it

Some crops require sub-inch accurate corrections to be produced with the most profitability, while others do not need such precision. Topcon offers correction accuracies from entry-level, sub-meter to high-accuracy, sub-inch.
All of the Topcon precision agriculture solutions start with GNSS (Global Navigation Satellite System) accuracy. Topcon receivers are all standard with GNSS dual-constellation (GPS + GLONASS) satellite reception. Topcon GNSS also offers TruPass™ mode for improved autonomous pass-to-pass accuracies.
Whether you are after entry-level guidance or need sub-inch, repeatable RTK (Real-Time Kinematics) accuracy, Topcon modular-designed products let your GNSS technology grow as your operation expands.

Featuring Topcon TruPass™ Advanced Positioning Technology

This compact, rugged receiver provides simultaneous processing of GPS and GLONASS signals with 32-channel high speed, universal tracking. The SGR-1 features Topcon TruPass advanced positioning technology for higher, more stable pass-to-pass accuracies in dynamic
ag applications. The SGR-1 outputs ground speed as simulated radar for fewer on board components during operations such as seeding and spraying.


Compact GNSS Positioning and RTK Correction

The HiPer V GNSS base station is compatible with Topcon receivers from field crop autosteering and machine control to water conservation and landforming. The HiPer V is a one-piece, cable-free unit that is rugged and compact featuring 226-channel Vanguard Technology™ along
with patented Fence Antenna™ technology for advanced performance. GNSS (GPS+GLONASS) tracking provides the ultimate in accuracy while offering field proven design.


Premium Portable Base Station

The latest GR-5 features the Topcon Vanguard GNSS chipset with 226 Universal Channel  Tracking Technology. The GR-5 also includes Topcon’s patented Fence Antenna™ technology design which offers a compact and lightweight antenna that covers the entire GNSS frequency band for unmatched performance.
With the Vanguard chipset, Fence Antenna, and Topcon’s advanced acquisition algorithms, the GR-5 receiver delivers the most robust GNSS tracking performance available.


Permanent Base Station
The MR-2 receiver delivers proven Topcon technology in a compact and easy to integrate package. It is ideally suited for permanent setups using an external antenna, external radio and separate power supply. It incorporates 72 Universal Tracking Channels and is capable of tracking all signals from GPS, GLONASS and SBAS satellite systems. The MR-2 is built for harsh environments, offering IP67 dust and water resistance as well as a superior level of vibration and shock tolerance.


Pushing out 35 watts, the SRL-35 provides reliable signal strength in the most challenging of environments. Built to IP67 standards, the light and portable radio features a weather-protected LCD display, integrated operator keyboard, and reinforced connectors. It can be used with an RTK base or as a stand alone RTK repeater.

AGI-4 Receiver/Steering Controller
The first truly modular ISO-compliant steering system

The AGI-4 comes standard with WAAS and EGNOS, but is easily upgradeable to 2 cm accuracy with RTK radio options. Like all Topcon receivers, the AGI-4 offers GNSS multi-constellation satellite reception standard for unmatched accuracy in dynamic applications and all terrain conditions.
The all-in-one, modular design incorporates the antenna, receiver and steering controller in a single component, offering unmatched upgradeability. The AGI-4’s ISO11783 compliant steering system features state-of-the-art inertial sensors and full terrain compensation for superior line acquisition and holding capabilities.
NTRIP capability allows tapping into existing reference networks via cellular connection (dependent of local availability) and uses existing data plans and infrastructure to minimize costs. In addition, the AGI-4’s ISO11783 compatibility with other Universal Terminals (UT) provides drop-in and drive convenience.
