Reach RS2

Reach RS2 is a multi-band RTK GNSS receiver with centimeter precision For surveying, mapping and navigation. Comes with a mobile app.

L1/L2/L5 RTK GNSS receiver with centimeter precision
Reach RS2 gets fixed solution in seconds and provides positional accuracy down to several millimeters. The receiver tracks GPS/QZSS (L1, L2), GLONASS (L1, L2), BeiDou (B1, B2), Galileo (E1, E5), and SBAS (L1C/A) and reliably works in RTK mode on distances up to 60 km, and 100 km in PPK mode. Multi-feed antenna with multipath rejection offers robust performance even in challenging conditions.

RINEX raw data logs are compatible with OPUS, CSRS-PPP, AUSPOS, and other PPP services so you can now get centimeter-precise results in any place on Earth.

Built-in 3.5G modem and UHF LoRa radio

Reach RS2 features a power-efficient 3.5G HSPA modem with 2G fallback and global coverage. The corrections can be accessed or broadcasted over NTRIP independently, without relying on Internet connection on your smartphone. For remote areas, Reach RS2 has built-in LoRa radio that has proven to be a reliable link for RTK corrections on distances up to 8 km.

Designed for tough conditions

Reach RS2 is engineered to be waterproof and impact-resistant. Its body is manufactured in a two-step injection process and is made out of shockproof polycarbonate covered in a special elastomer for extra protection. The receiver has an industry-standard 5/8'’ mounting thread.

The LiFePO4 battery of Reach RS2 is designed for 16 hours work as 3.5G RTK rover on one charge regardless of weather conditions. No more need to carry spare batteries with you. Reach RS2 can charge from a USB wall charger or a power bank over USB-C. RS232 interface allows to connect Reach RS2 directly to external hardware and output position in NMEA.

Survey with ReachView app

Reach RS2 comes with a mobile app ReachView for iOS and Android, that is used to control all the features of the device. Create projects, collect and stakeout points. Import and export geodata in industry standard formats such as CSV, DXF, and ESRI Shapefile.
