Multi-band RTK GNSS receiver with centimeter precision
Note: Shipments begin in mid-June.
For surveying, mapping and navigation. Comes with a mobile app. Manufactured by Emlid. This product is the multi-frequency version of the single frequency Emlid Reach RS+. Utilizing multiple frequencies allows the RS2 to achieve faster time to first fix, more reliable fix maintenance, and longer baselines. The RS2 has other advanced features not available on the RS+. See below for more details.
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.
DXF, CSV, GeoJSON
Create projects and save points with custom name and description. Set rules for data quality. Data collection is fast and intuitive, because ReachView is designed to feel like most popular map apps.
ReachView can guide you to any point like a navigator. On distance 50 cm from a point app’s interface turns into bullseye view. Move the receiver to align bubbles on the screen, when interface turns green—you are on the point.
Record raw data, position and base correction logs.
16 GB storage allows for 160+ days of logging at 1 Hz
