Getting Started with Your GNSS Receiver
From unboxing to your first position fix in minutes. Follow these steps to set up your Eview GNSS receiver correctly the first time.
Eview GNSS receivers are designed for rapid deployment.
Most users achieve a first fix within 5 minutes of setup.
Step-by-Step Setup Guide
Follow these steps in order. Each step takes 1–3 minutes. If you encounter an issue, see the troubleshooting tips at each stage or contact our support team.
Check the Box Contents
Before powering on your unit, confirm you have received all items. Your package should include the receiver unit, a USB cable, and a quick-start card. Antennas and mounting hardware may be included depending on your order configuration.
- GNSS receiver or OEM board
- USB-A to USB-C or micro-USB cable
- Quick-start reference card
- Antenna (if ordered with receiver kit)
- Mounting bracket or enclosure (if applicable)
- Packing slip / invoice
Connect the GNSS Antenna
Your receiver requires an external GNSS antenna to acquire satellite signals. The antenna connector is typically a TNC or SMA female port on the unit housing (or a U.FL connector on OEM boards).
- Use an active multi-band antenna (L1/L2/L5 or L1/L2 as applicable)
- Place the antenna with a clear view of the sky — no obstructions above 10°
- Avoid placing near metallic surfaces that could cause multipath reflections
- For OEM boards, connect via U.FL-to-SMA pigtail cable
- Ensure the antenna cable is routed away from power lines and motors
- Tighten connectors finger-tight — do not over-torque
Power the Receiver
Eview GNSS receivers can be powered via USB (5 V) or an external DC supply (7–36 V depending on model). For initial setup and testing, USB power from a laptop or powered hub is the simplest option.
- Connect USB cable to receiver and to a laptop or powered USB hub
- A power LED or status LED will illuminate on the receiver housing
- For field deployment, use the specified DC input voltage for your model
- Never exceed the maximum input voltage — see product datasheet
Install USB Drivers (Windows)
On Windows, your receiver will appear as a USB-to-Serial COM port. Most receivers use a CP210x or FTDI USB chip which requires a driver on first use. macOS and Linux typically detect these chipsets automatically.
- Connect the receiver to your Windows PC via USB
- Open Device Manager — look for “Ports (COM & LPT)”
- If a yellow warning icon appears, the driver needs installation
- Download the CP210x driver from Silicon Labs, or FTDI driver from ftdichip.com
- After installation, note the COM port number assigned (e.g., COM4)
- On macOS, the device appears as /dev/tty.usbserial-xxxxx
Open the Configuration Software
Eview receivers based on Septentrio mosaic modules can be accessed via RxTools or the built-in web interface. Unicore-based receivers (UM980, UM982 series) can be configured using UNICORE Message Analyst or any serial terminal.
🛰 RxTools (mosaic-X5 / mosaic-H)
Septentrio’s RxTools provides a full GUI for configuring mosaic receivers, monitoring signal quality, and logging raw data.
Download RxTools →📊 UNICORE Message Analyst (UM980 / UM982)
UMA is the official Windows application for configuring and monitoring Unicore GNSS receivers. Connect via COM port at 115200 baud.
Download UMA →💻 Serial Terminal
Any serial terminal (CoolTerm, PuTTY, TeraTerm) works for command input and NMEA monitoring. Set baud rate to 115200, 8N1.

Once the receiver is powered with an antenna connected and sky view available, it will begin acquiring satellite signals. Cold start time-to-first-fix (TTFF) is typically under 60 seconds in open sky.
Single-Point Fix
3D position with 4+ satellites. Accuracy ~1–3 m. Sufficient for basic applications.
SBAS Fix
Differential correction via WAAS/EGNOS. Accuracy ~0.5–1 m. No external connection required.
RTK Fixed
Centimetre-level accuracy. Requires NTRIP or base station corrections. Best performance.
