Full Constellation
M40 delivers rapid, stable fixed solutions in just seconds, even in challenging environments such as urban canyons, under tree cover, or areas with severe multipath interference. Featuring full-constellation robust signal tracking, advanced anti-interference capabilities, and a sophisticated RTK algorithm, it ensures high-performance positioning reliability.
Long Baseline
Supporting standard RTCM correction data transmission, the M40 achieves outstanding performance with a transmission range of up to 15 km in enhanced internal UHF mode, 20 km in external UHF mode, and over 50 km via PDA CORS mode under optimal conditions.
60° Tilt Five Seconds Initialization
Featuring an optimized next-generation IMU module, the system enables fast initialization in just 5 seconds, supporting tilt measurements of up to 60°. A single initialization maintains accuracy within ±2.5 cm throughout the entire work session, ensuring consistent and reliable performance.
Over 20 Hours Operation
M40 features an integrated internal battery design that enhances charging safety, waterproof performance, and internal structural efficiency. With a fast 3-hour charge via the Type-C port, it delivers over 20 hours of continuous operation. Additionally, it supports power bank charging, enabling convenient on-the-go power replenishment.
IP68 Design
M40’s rugged housing ensures reliable protection, safeguarding the device from damage even in heavy rain, dusty conditions, or if accidentally dropped onto concrete or into water. Built to withstand harsh environments, it delivers durable performance when you need it most.
