Positioning & Navigation Systems
Maintain Centimeter-Level Accuracy even when GPS fails. Tightly coupled GNSS + INS Fusion for autonomous driving, mapping, and robotics in challenging urban environments.
Tactical Grade INS
Ultra-precision MEMS-based fusion for HD mapping and L4 autonomy. Maintains minimal drift during long tunnel outages.
Industrial GNSS/INS
Compact, cost-effective RTK fusion for delivery robots, mining vehicle, and logistics AGVs.
Dual-Antenna Systems
True heading without magnetic interference. Ideal for slow-moving machinery. Fast heading and output stable heading in the static state.
GNSS Antennas
The satellite GNSS board card supports multiple constellations and multiple frequency bands.
Continuous Positioning Anywhere
From urban canyons to obstructed canopies, see how DAISCH GNSS/INS systems provide uninterrupted, centimeter-level accuracy in the most challenging environments.
Survival in GNSS-Denied Zones
Standard loose-coupled systems fail here. DAISCH Tactical INS uses Tightly Coupled fusion. We fuse raw satellite observables with high-end IMU data, allowing the system to bridge long outages with minimal drift.
- Feature: Tunnel Dead-Reckoning (Outage Survival)
- Accuracy: < 0.25% Distance Traveled Error
Interference-Free Heading in Iron Mines
Eliminate magnetic interference risks. Our Dual-Antenna INS derives heading directly from satellite baselines, ensuring precise orientation for autonomous haulage and driver assist systems—even when the truck is completely stationary.
- Feature: Immune to Magnetic Interference
- Heading Accuracy: 0.15° (1m baseline)
Precision Under the Canopy
You need centimeter-level accuracy without the military price tag. Our Industrial GNSS/INS combines multi-band RTK (L1/L2/L5) with cost-effective MEMS fusion to maintain lane-level accuracy in partially obstructed environments.
- Tech: Multi-Band RTK + MEMS Fusion
- Interface: NTRIP Client Ready

Precision that survives the tunnel.
When satellites fail, algorithms must take over. DAISCH systems utilize deep sensor fusion to maintain centimeter-level accuracy even in the most hostile signal environments.
Tightly Coupled Fusion
We don't just mix positions. We fuse raw satellite observables (Carrier Phase) directly with IMU data. Even with only 2 satellites visible, we maintain a constrained trajectory.
- Algorithm: Raw Data Fusion
- Outage Drift: < 0.2% Dist Traveled
Urban Multipath Rejection
City canyons create "ghost" signals from glass buildings. Our integrity monitoring algorithms detect and isolate Non-Line-of-Sight (NLOS) signals before they corrupt the solution.
- Tech: Signal Integrity Monitor
- Env: Urban Canyon Proven
Production Consistency
GNSS/INS performance relies on precisely eliminating installlation error. We automate this in our factory, ensuring every unit matches the datasheet specs, volume after volume.
- Calibration: Eliminate installlation error
- Standard: IATF 16949 Certified
