Which Solution Is Best for Your Application?
UAV / Drone mapping
Eview provides OEM modules for integration into UAV payloads or as a base station. Lightweight, low-power, with AIM+ for RF-noisy environments near motor ESCs.
Choose Eview GNSSTopographic survey (field)
Emlid RS4 Pro is a complete field instrument with tilt compensation, dual cameras, and a polished mobile app — requiring no integration work.
Choose EmlidPrecision agriculture / auto-steer
Eview UM982 provides dual-antenna heading and RTK positioning for tractor auto-steer integration. Emlid Reach M2 is also used in this application.
Either — depends on integrationEnvironments with RF interference
Eview receivers with AIM+ actively suppress jamming signals. Critical for deployments near high-power radios, industrial sites, or urban environments with known jammer threats.
Choose Eview GNSSMarine / vessel positioning
Eview mosaic-H provides dual-antenna heading over NMEA 0183 for chart plotters. Wider operating temperature and proven in marine environments.
Choose Eview GNSSConstruction stakeout
Emlid RS4 Pro with ReachView 3, tilt compensation, and AR stakeout camera excels at layout work on construction sites. No custom integration required.
Choose EmlidVerdict
Choose Eview GNSS when:
You need to integrate GNSS positioning into a larger system — UAV autopilot, agricultural machine controller, robot, marine chartplotter, or industrial device. Eview’s AIM+ anti-jamming and OSNMA anti-spoofing make it the right choice when signal integrity matters. Wider operating temperature range suits harsh outdoor deployments.
