A98L Laser Dual Camera RTK, Pioneering Safer & Smarter Surveying

A98L Laser Dual camera RTK, a next generation integrated solution combining full constellation GNSS positioning, green laser ranging, dual camera AR stakeout and IMU inertial navigation. Designed for high risk, hard to reach and contact prohibited scenarios, the A98L sets a new benchmark for non contact, high efficiency and high precision field surveying.

Powered by a 1408 channel positioning engine, the A98L supports full system and full frequency signals from BDS, GPS, GLONASS, Galileo, QZSS, NAVIC and SBAS, as well as PPP services. It delivers a 20Hz standard update rate, cold start in <12 seconds, initialization in <5 seconds and reliability >99.9%, ensuring stable fixed solutions even in dense forests and complex urban environments.

At the heart of the device is a 520nm green visible laser (Class 3 safety), offering a measuring range of 0.1–25m, up to 20Hz ranging frequency, 1mm resolution and ±2mm accuracy at 10m. The highly visible green spot remains clear under strong sunlight, enabling truly non contact measurement to keep operators away from hazards.

Paired with a high performance IMU module, the A98L supports 60° tilt measurement with accuracy within 2cm, allowing instant point and measure operation without strict centering. Dual 2 MP HD cameras (90° front, 72° bottom) enable AR assisted stakeout, combining long range guidance and close range centering to boost overall efficiency by 39%.

Built for harsh field conditions, the A98L features a lightweight magnesium aluminum alloy body (weight <900g), IP67 waterproof and dustproof rating, 2 m pole drop resistance and an operating temperature range of 30°C to +70°C. The large capacity 13400mAh battery supports over 18 hours in static mode and 12+ hours in RTK mode, supporting all day field tasks.

In terms of connectivity, the unit runs on Linux with 8G internal memory, and supports 4G, Wi Fi, Bluetooth 5.0 and a 2W UHF radio. It is compatible with mainstream protocols including TrimTalk450s, Satel and South, ensuring stable data transmission in various working modes.

The A98L is widely applied in hazardous areas, cultural heritage sites, piers & bridges, dense forests, roadway infrastructure and waterway surveys, providing safe, efficient and high precision measurement across challenging scenarios.
