FAQ
Frequently Asked Questions
What industries use GNSS technology?
GNSS technology is used across a wide range of civilian industries including UAVs and drones (mapping, inspection, delivery), land surveying and GIS, construction machine control, mining fleet management, precision agriculture (auto-steer, crop robots), robotics and autonomous vehicles, marine navigation and hydrographic survey, eVTOL and urban air mobility, logistics and rail transit, structural deformation monitoring, precision timing for telecom and power grids, and aerospace research. Eview GNSS serves all these verticals with Septentrio-powered receivers.
What is the best GNSS receiver for UAVs and drones?
The best GNSS receivers for UAVs are lightweight, compact, multi-frequency modules with RTK capability and active anti-jamming protection. Eview’s Mosaic Click and Linnet modules — based on Septentrio’s AIM+ technology — are optimized for drone integration, offering centimeter-level RTK accuracy, fast satellite acquisition, and AIM+ interference protection in a weight-optimized form factor. They are compatible with Pixhawk, ArduPilot, and other popular flight controllers.
Which GNSS receivers are best for construction and machine control?
Construction machine control requires GNSS receivers with centimeter RTK accuracy, vibration tolerance, and robust interference rejection (construction sites are RF-dense environments near power lines and radio towers). Eview’s Mosaic M-2 and HB6 receivers deliver <1 cm RTK accuracy with AIM+ suppressing up to 60 dB of interference — far exceeding consumer-grade alternatives. They support dual-antenna heading for machines requiring accurate orientation, not just position.
How is GNSS used in precision agriculture?
In precision agriculture, GNSS is used for auto-steer guidance (sub-inch accuracy for pass-to-pass operations), variable rate application, precision planting, yield mapping, and autonomous agricultural robots (crop sprayers, weeding robots, orchard navigation). RTK GNSS receivers connected to NTRIP correction networks deliver the centimeter-level accuracy needed for tight guidance lines and eliminate operator fatigue on long cultivation passes.
What is Assured PNT (APNT) and who needs it?
Assured Positioning, Navigation, and Timing (APNT) refers to GNSS solutions designed to maintain accurate positioning and timing even when signals are jammed, spoofed, or unavailable. APNT is critical for applications where signal disruption would cause safety, financial, or operational consequences — including 5G telecom synchronization, power grid monitoring, financial transaction timestamping, autonomous vehicles, and critical infrastructure. Eview’s AIM+ receivers provide the interference-resilient foundation for civilian APNT deployments.
Can Eview GNSS receivers be used for structural monitoring?
Yes. Structural deformation monitoring requires GNSS receivers capable of detecting sub-millimeter displacement over time — typically using static or slow-moving observation modes with long-baseline RTK or PPP. Eview GNSS receivers support high-precision static positioning with mm-level repeatability, making them suitable for continuous monitoring of bridges, dams, retaining walls, high-rise buildings, and slope stability in geotechnical applications.
