What is GNSS+INS? Revealing the "dual-core engine" of High-Precision Navigation

1. GNSS+INS: The golden combination in the field of navigation

GNSS (Global Satellite Navigation System) such as Beidou/GPS provides absolute position, but it is easy to fail in tunnels and canyons;
INS (Inertial Navigation System) autonomously calculates the motion trajectory through gyroscopes and accelerometers, but the error will accumulate.
✅ The fusion of the two = global accuracy of satellite positioning + instantaneous stability of inertial navigation, achieving all-weather, zero-interruption high-reliability navigation!

2. ER-GNSS/MINS-03: The pinnacle of fusion technology

▶️ Hardcore dual system configuration
“INS core”: high-precision MEMS sensor
→ Gyroscope zero bias <0.3°/h
→ Accelerometer zero bias <5μg
“GNSS core”: dual antenna full-band positioning
→ Support Beidou/GPS/GLONASS/Galileo/QZSS five major systems
→ Built-in RTK positioning board
▶️ High-precision hold function
Satellite signal loses lock for 30S, can maintain attitude accuracy of 0.01°, heading accuracy of 0.02°.
Satellite signal loses lock for 60S, can maintain attitude accuracy of 0.02°, heading accuracy of 0.03°.

▶️ Lightweight design & full interface industrial adaptation
▸ Aluminum alloy shell | <300g ultra-lightweight
▸ Support RS422/RS232/CAN three industrial bus protocols

🌐 Empower cutting-edge application scenarios:

► UAV/flight recorder: precise attitude determination in complex airspace
► Roadbed positioning & channel detection: high-precision detection guarantee
► High dynamic carrier: full-field adaptation of aviation and land

Summary

"GNSS+INS is not a simple superposition, but through the integrated navigation fusion algorithm to make 1+1>2. The 0.02° attitude accuracy of ER-GNSS/MINS-03 is the double victory of algorithm and hardware."
