How can the ultra-high cost-effective combined navigation make the equipment "stable as a mountain" in complex environments?

UAVs in tunnels suddenly lose control, deep-sea exploration robots drift in positioning, and self-driving cars get "lost" under overpasses - behind these scenes, the essence is the failure of single navigation technology in dynamic environments. Traditional solutions either rely on expensive high-end inertial devices or quickly collapse when the signal is interrupted. Today, ERICCO's ER-GNSS/MINS-03 combined navigation system is breaking through this dilemma with subversive cost-effectiveness.

Core logic: Why is "dual system" necessary?

The reliability of the navigation system depends on environmental adaptability and error control capabilities:
GNSS (satellite positioning): high accuracy in open environments, but signals are easily lost in tunnels/urban canyons;
INS (inertial navigation): fully autonomous, but errors accumulate over time.

The breakthrough of ER-GNSS/MINS-03 is:

Through algorithm-level fusion, the absolute accuracy of GNSS and the short-term stability of INS are mutually "insured":
When the satellite signal is good, INS calibrates the zero bias of the gyroscope and accelerometer in real time;
When the signal is interrupted, INS continues navigation based on the high-precision inertial reference (the loss of accuracy is controllable).
This "dual-system mutual error correction" mechanism has become the underlying pillar of continuous navigation in complex environments.
II. Key innovation: How to achieve "low cost and high reliability"?

▶ Tactical-grade MEMS inertial devices
Equipped with tactical-grade high-precision and high-reliability MEMS gyroscopes (zero bias instability <0.3°/h) and high-precision MEMS accelerometers (zero bias instability <5ug), it can maintain excellent sensor performance while reducing costs.

▶ "Triple Defense" Design of Dual-antenna GNSS
Integrated dual-antenna full-system full-frequency positioning and orientation satellite modules, it can perform RTK positioning and dual-antenna orientation solution, single-antenna positioning and speed measurement, and dual-antenna rapid orientation. The satellite receiver has built-in anti-interference function, which can still provide accurate and reliable satellite positioning in complex electromagnetic environments;

▶Strong accuracy retention capability
In the environment where the satellite signal is lost, it maintains 30s of high-precision navigation, attitude (accuracy 0.01°), heading (accuracy 0.02°)

Summary

ER-GNSS/MINS-03 does not rely on the sky-high fiber optic gyroscope, and uses algorithm compensation to achieve the extreme stability of MEMS;
Without piling up hardware costs, it uses a dual-system coupling mechanism to build navigation resilience. We use a reasonable cost to obtain navigation performance comparable to high-end equipment.
