Main Features and Advantages​

Multi-Constellation Precision Positioning:Supports 550+channels and six satellite systems(北斗、GPS、GLONASS等),delivering RTK-level accuracy for critical tasks.A land surveying company in China used the AGPS-21C for highway alignment measurements—its 3mm horizontal accuracy reduced survey errors by 90%compared to traditional GPS modules,cutting rework time by 40%and saving$15,000 per project.​

AGPS+5G Seamless Navigation:Combines satellite signals with cellular auxiliary positioning to eliminate dead zones.A logistics firm in Germany deployed the module on 200 delivery trucks—when entering urban canyons or underground parking lots,AGPS-21C switched to 5G-assisted positioning,maintaining<1m accuracy(vs.10m+with standard GPS),ensuring on-time deliveries and reducing customer complaints by 25%.​

Harsh-Environment Durability:IP67 waterproofing and-40℃~+85℃operating range withstand extreme conditions.A mining operation in Australia installed the AGPS-21C on underground loaders—its dustproof housing and wide temperature tolerance prevented signal loss in 40℃+tunnels,enabling real-time fleet tracking and reducing equipment misplacement incidents by 80%.​

Industrial System Compatibility:Modbus protocols enable integration with PLC/SCADA systems.A smart agriculture company in the US paired the module with ABB AC500 PLCs for autonomous tractor navigation—the AGPS-21C transmitted position data via Modbus RTU,allowing the PLC to adjust tractor paths with 5cm precision,increasing crop yield by 12%and reducing fuel consumption by 18%.​

Application Field​

The AGPS-21C excels in surveying and construction,where precision is non-negotiable.A bridge construction company in Japan used 30+modules for pile driving alignment—each AGPS-21C provided RTK data to a central SCADA system,ensuring piles were placed within 3mm of design coordinates,avoiding costly rework and accelerating project completion by 3 weeks.​

In logistics and fleet management,the module enables real-time asset visibility.A shipping company in Singapore integrated it with container tracking systems—when containers moved between ships,ports,and warehouses,the AGPS-21C maintained<1m accuracy(even in port terminals with heavy metal interference),reducing container loss by 95%and improving inventory turnover by 30%.​

Energy and mining industries rely on its rugged design.A power grid operator in Brazil deployed the module for transmission line inspection drones—the AGPS-21C’s 5mm vertical accuracy ensured drones stayed 3m clear of lines,while its low power consumption(1.2W)extended flight time by 2 hours,covering 50%more line mileage per day.A petroleum company in Canada used it to track offshore drilling equipment—the IP67 rating withstood saltwater spray,and 5G-assisted positioning worked in foggy conditions,ensuring equipment stayed within safety zones.​

Installation and Maintenance​

Pre-installation preparation:Before installing AGPS-21C,select a location with unobstructed sky view(for satellite signals)and cellular coverage(for AGPS).For DIN rail mounting,clean the 35mm rail and ensure 20mm clearance for heat dissipation;for outdoor use,attach the waterproof bracket and seal cable entry points.Verify the operating environment(-40℃~+85℃,humidity≤95%non-condensing)meets specifications.​

Wiring and configuration:Connect the external antenna(e.g.,Trimble R12i)to the module’s SMA port—use shielded cables to reduce EMI.Wire the 9V~36V power supply(observing polarity)and communication port(RS485/Ethernet)to the PLC/SCADA system.Configure satellite constellations(e.g.,北斗+GPS)and update rate(1Hz~20Hz)via Windows-based software.Insert an optional SD card for logging,setting intervals(1s~10min)via the configuration tool.Power on the module and verify LED indicators:green(power),blue(satellite lock),amber(AGPS active)—solid blue indicates≥8 satellites tracked.​

Maintenance recommendations:Conduct monthly visual inspections—check antenna connections,housing for damage,and LED status.Every 6 months,update the module’s firmware via the manufacturer’s portal to enhance satellite compatibility(e.g.,new北斗satellites).Clean the antenna with a damp cloth quarterly to remove dust/snow.For outdoor installations,inspect waterproof seals annually and replace if cracked.If satellite lock is lost(flashing blue LED),check antenna alignment first—if issues persist,use the self-test function to verify hardware integrity and replace with a certified unit.​
