About the eSA2 GNSS Receiver.
The eSurvey eSA2 is a compact, wearable smart-antenna GNSS receiver that turns an ordinary Android phone or tablet into a professional, centimetre-accurate survey and GIS tool. At just 210 g in a rugged metal-shelled IP67 body, it can be worn in an armband bag, slipped into a pocket or pole-mounted, ideal for mobile mapping where carrying a full data collector is impractical.
It tracks 1,408 channels across all major constellations, including full BeiDou-3, connects to the field device by Bluetooth, and supports tilt-compensated measurement up to 110 degrees. A lightweight, low-cost route to high-accuracy positioning.
Built to make the job faster.
Wearable design
At 210 g or less in a metal shell, the eSA2 can be worn on an armband, carried in a pocket or pole-mounted for flexible, fatigue-free surveying.
Turns any phone into a survey tool
Built-in Bluetooth pairs the eSA2 with Android devices, removing the need for a heavy, expensive dedicated data collector.
110 degree tilt survey
Tilt compensation up to 110 degrees lets you measure accurate points while standing or walking, with no pole levelling.
Full-constellation tracking
1,408 channels track GPS, GLONASS, Galileo, BeiDou (full BDS-3) and QZSS plus SBAS for fast, reliable centimetre positioning.
CORS centimetre accuracy
A high-precision GNSS module delivers centimetre positioning from CORS corrections, with RTK accuracy of H 2 cm + 1 ppm.
Rugged, all-day capable
IP67 sealing, a 1.6 m drop rating and a battery giving 10 hours or more keep it dependable for a full day.
