TOKNAV is the GNSS brand of Guangzhou Toksurvey Information Technology Co., Ltd., a company set up by senior engineers in Guangzhou, China. Over the years they have focused on designing, building, and supporting high‑precision GNSS equipment for professional use. Today, TOKNAV is known for solid accuracy, reliability, and portable receivers that survive real jobsite conditions.
You will see TOKNAV gear on survey and mapping crews, precision agriculture, machine control on construction equipment, and deformation monitoring projects. The brand is now distributed in dozens of countries (Rise Geo Control Systems in Dubai, U.A.E.), with users spread across several continents.
Real-Time Kinematics (RTK) Solutions
TOKNAV offers a full family of RTK receivers aimed at surveyors, engineers, and machine control operators. They are built for land development, building and infrastructure projects, and any work that demands repeatable, centimeter‑level positioning.
Below is a practical overview of the main models.
TOKNAV tBase – Dedicated GNSS Base Station
The tBase is TOKNAV’s fixed base receiver, designed specifically to be placed on a tripod or pillar and broadcast corrections all day.
What it brings to site
- Full‑system GNSS tracking with 1408 channels, covering GPS, GLONASS, BDS, Galileo and QZSS on multiple frequencies.
- Linux + ARM Cortex‑A7 platform, which keeps the receiver responsive and allows extra functions to be added as the firmware evolves.
- Built‑in communication: 4G, Bluetooth, Wi‑Fi and a 5W UHF radio, so you can run network and radio links in parallel in the same kit.
- Rugged build: 32 GB internal storage and a magnesium alloy housing with IP68 protection for dust and water.
- Long range and runtime: the 5W radio and 13,800 mAh battery are designed for ranges of up to about 16 km in open country and roughly a full working day of operation.
Typical performance
The tBase supports standard accuracy modes:
Single: about 1.5 m horizontal / 2.5 m vertical (RMS)
DGPS: about 0.4 m horizontal / 0.8 m vertical
RTK: roughly ±(2.5 mm + 1 ppm) horizontal / ±(5 mm + 1 ppm) vertical
Static surveys can reach similar precision of just a few millimeters plus a small amount based on distance, with timing and speed
Tilt correction is supported up to about 60° with better than 2 cm accuracy when set up correctly.
A built‑in VPN option allows you or your support team to log in remotely, change settings, and troubleshoot without physically visiting the base station.
TOKNAV T10Pro – Lightweight Rover for Everyday Survey
The T10Pro is a compact, light rover aimed at land survey and general engineering tasks where you are on your project all day.
Key ideas
- Linux + Cortex‑A7 platform for stable, updatable operation.
- Four‑in‑one combined antenna (GNSS, Wi‑Fi, Bluetooth, 4G) to keep the housing small and improve signal quality.
- 1408‑channel engine that tracks GPS, GLONASS, BDS, Galileo, QZSS and SBAS across all main survey bands.
- Rugged housing, IP68 rating and 32 GB internal storage for typical field logging.
- Internal battery (3.7 V, 9600 mAh) sized for a normal working day.
In use, the T10Pro delivers:
- Single and DGPS accuracies in the meter to sub‑meter range.
- Millimeter‑plus‑ppm precision in static mode.
- An IMU with up to 60° of tilt and around 2 cm accuracy once initialized, which lets you measure points without keeping the pole perfectly vertical.
It also includes an internal UHF radio (410–470 MHz, common protocols like TRIMTALK, SOUTH, etc.) with around 0.5–1.5 W output, suitable for typical rover ranges around a base.
TOKNAV T20Pro– Tilt Rover with Built‑In 5 W Radio
The T20Pro steps up from the T10Pro for crews that want a built‑in high‑power radio and a simple front panel.
In practice you get
- The same Linux + Cortex‑A7 platform and 32 GB storage.
- IP68 protection and a slightly larger battery (7.4 V, 6500 mAh) for longer runtime.
- A Four‑in‑One Antenna with the same multi‑constellation, multi‑frequency tracking (GPS, GLONASS, BDS, Galileo, QZSS, SBAS).
- Full support for correction protocols such as RTCM 3.x.
On the communication side:
- Internal 4G modem that works with the usual LTE FDD/TDD, WCDMA and GSM bands used in many regions.
- Internal UHF radio with 1/2/5 W selectable power, 410–470 MHz range, and support for the major survey radio protocols. In base mode at 5W in open country, ranges around 16 km are realistic under good conditions.
The T20Pro suits survey teams who frequently switch between base and rover mode and want radio and network in a single receiver.
TOKNAV T30 GNSS Receiver
The T30 is the flagship receiver, aimed at projects that need long battery life, rich communications and advanced stakeout tools.
Main capabilities
- Linux + Cortex‑A7 platform, with enough processing headroom for AR and laser functions.
- Full‑system GNSS tracking (1408 channels) across all main bands on GPS, GLONASS, BDS, Galileo, QZSS and SBAS.
- Support for RTK via base stations or CORS networks, typically using NTRIP for internet corrections.
- Full‑Netcom 4G: works with the main 2G/3G/4G networks used by most operators.
The T30 also adds:
- A millimeter‑level laser range module integrated with the inertial navigation system, useful for offset shots and measurements in tight or obstructed locations.
- Augmented Reality stakeout via a wide‑angle camera, so you can see design points and lines overlaid on the live camera view. This can speed up layout work and reduce mistakes.
- A large 7.2 V, 13,800 mAh battery that is built to last for roughly two standard field days on a single charge, depending on radio and data use.
TOKNAV pairs the T30 with its PCR100T data controller, a rugged handheld designed for RTK work that meets IP68 protection and ties into the AR and laser functions.
