Overview

Professional-Grade GNSS for Every Survey Application

Modern surveying demands centimeter-level accuracy, rapid initialization, and resilient performance across every environment — from dense urban canyons to remote open-sky terrain. Eview GNSS receivers combine full RTK/PPK capability with Septentrio AIM+ technology to deliver reliable, accurate positioning regardless of RF conditions.

Whether you are running a total-station replacement with a GNSS pole, collecting GIS features from a vehicle-mounted mobile mapping system, or monitoring structural deformation over months, Eview receivers deliver the accuracy and reliability demanded by professional surveyors and GIS technicians.

FAQ

Surveying & GIS GNSS — Frequently Asked Questions

What is the difference between RTK and PPK for surveying?
RTK delivers real-time centimeter accuracy via a live correction link (NTRIP/radio). PPK records raw GNSS observations and applies corrections post-flight or post-survey — eliminating the need for a real-time link and allowing corrections from the closest base station. Eview receivers support both workflows from the same hardware.
Can Eview GNSS receivers be used with GIS software like ESRI and QGIS?
Yes. Eview receivers output standard NMEA 0183 sentences (GGA, VTG, RMC, GST) compatible with all major GIS field collection software including ESRI ArcGIS Field Maps, QGIS, Trimble TerraFlex, and Collector. Raw data can be exported in RINEX format for post-processing.
How does AIM+ improve GNSS performance in urban survey environments?
Urban environments combine multipath signals from buildings, RF interference from cellular infrastructure, and frequent satellite obstruction. AIM+ actively suppresses jamming signals while APME+ multipath mitigation filters reflected signals — maintaining reliable RTK fix in conditions that would degrade standard receivers.
What is the minimum number of satellites needed for RTK?
RTK typically requires a minimum of five visible satellites from at least one constellation for a reliable fixed solution. With multi-constellation tracking (GPS, Galileo, BeiDou, GLONASS), Eview receivers maintain RTK availability even in partially obstructed environments like urban canyons and forested areas.
