Toknav T40 & T40Pro RTK: Smart Tools for Easy Surveying
2026-02-19
Surveying work needs tools that are precise and easy to use. Toknav’s T40 series—T40 and T40Pro—hits that sweet spot. These GNSS receivers mix high accuracy with simple, practical features. Whether you need laser measurement (T40) or photogrammetry (T40Pro), they cut down hassle and boost on-site efficiency. Today, we’ll break down their specs, key differences, and why they fit real surveying tasks.
1. What Makes Toknav T40 Series Stand Out?
Many RTK receivers are either too complex to learn or not tough enough for daily use. Toknav fixes this with the T40 series. They focus on “no-fuss functionality” for teams that need consistent results, fast.
First, both models have a durable magnesium alloy build—light (850g) but IP68-rated to handle rain and drops. Second, they support hot-swappable batteries, so you never stop working to charge. Third, they skip confusing settings: turn them on, connect the controller, and start surveying. Whether you’re staking points or measuring hard-to-reach spots, these RTKs keep work smooth.
2. Core Specs: T40 vs. T40Pro
T40 and T40Pro share Toknav’s practical design but serve different needs. Below is a clear breakdown of their key specs.
2.1 Shared Foundation: Precision & Durability
Every T40 receiver starts with a strong core, ensuring reliable performance every time.
GNSS Support: BDS, GPS, GLONASS, Galileo, QZSS, SBAS; 1408 high-speed channels for fast signal capture.
Positioning Accuracy: RTK horizontal ±(8mm+1ppm), vertical ±(15mm+1ppm); <2cm tilt compensation (≤60°).
Build: Magnesium alloy body, IP68 protection, 1.5m drop resistance; 850g (without battery) for easy carrying.
Battery: 7.2V 3400mAh dual hot-swappable batteries; ≥20 hours of use (controller network mode).
2.2 Key Differences: Laser vs. Photogrammetry
Each model adds unique tools to fit specific surveying jobs.
T40: Green laser measurement (30m range, ±5mm precision) + laser assist camera. Perfect for quick spot measurements—like checking distances to walls or pipes.
T40Pro: Photogrammetry camera (1/2.6-inch sensor, 2-4cm error within 15m). Great for 3D mapping or extracting coordinates from real-world images.
Shared Perk: AR stakeout (1920*1080 HD camera) for intuitive, one-shot point staking.
2.3 Control & Practical Features
Both RTKs keep operation simple, even for new users.
Display: 1.3-inch 240RGB240 LCD panel—clear to read in sunlight.
Giao tiếp: 410~470MHz radio (1W/2W/5W), Bluetooth, Wi-Fi; supports common protocols like TRIMTALK.
Software: Works with Toknav’s easy-to-use controller apps—no complex training needed.
3. How to Choose: T40 or T40Pro?
Pick the model that matches your daily tasks:
Choose T40 if you need laser measurement. It’s ideal for small-site surveys, utility checks (like pipe distances), or quick stakeouts where you need to “point and measure” fast.
Choose T40Pro for photogrammetry. It’s perfect for topographic mapping, construction progress tracking, or jobs where you need to turn photos into precise coordinates.
For AR stakeout (like land boundary marking), both work great—T40 adds laser speed, while T40Pro adds image-based flexibility.
4. Why Surveyors Love the T40 Series
Beyond specs, these RTKs solve real on-site problems:
No Downtime: Hot-swappable batteries mean you can replace a dead battery in seconds—no stopping work.
Light & Tough: Easy to carry all day, yet strong enough to handle rain, dust, and accidental drops.
Simple to Learn: Intuitive controls let new team members start using them in minutes, not hours.
Consistent Accuracy: Tilt compensation and fast RTK initialization (cold start <40s) reduce errors.
5. Conclusion: T40 Series—Surveying Made Easier
Toknav T40 and T40Pro aren’t just RTKs—they’re time-savers for busy surveyors. T40 keeps quick measurements fast and simple; T40Pro turns photos into precise data for bigger projects.
Both skip the overcomplicated features and focus on what matters: reliability, ease of use, and all-day performance. They fit how you actually work—no more fighting with confusing settings or fragile gear.
Quick question: Do you mostly do quick spot measurements or need 3D mapping from photos? Have you ever struggled with RTKs that die mid-job? Drop a comment—I’ll help you pick the right T40 model!
