  • High-precision IMU With Tilt Compensation: Survey with under 20mm precision at up to 60° tilt. It is immune to magnetic disturbances, ensuring accuracy.

  • Rapid Fix: Obtain a cm-accurate solution in five seconds. Signals tracked: GPS/QZSS, GLONASS, BeiDou, and Galileo.

  • High Endurance: Industrial-grade battery can endure up to 22 hours of logging or 18 hours as an RTK rover with tilt compensation.

  • RINEX Logging and PPP Support: Raw data is recorded in RINEX format for post-processing. Use Emlid Studio, or any other software with RINEX support. Logs are also compatible with OPUS, AUSPOS, and PPP services.

  • Built-in LTE Modem: Insert a SIM card into Reach RS3 and let it broadcast or receive corrections via NTRIP.

  • Rugged: The receiver is dustproof and waterproof to IP67 with an operating temperature of -20° to 65°C.

Reach RX

  • Pocket-sized Receiver: Reach RX weighs 250g and is small enough to be carried in your pocket.

  • Precision Data: Works with any corrections network (NTRIP) to provide centimetre-precise positioning. It tracks GPS/QZSS, Galileo, GLONASS, and BeiDou and gets a FIX in under 5 seconds.

  • Rapid Set-up: Only requires the NTRIP configuration to be added.

  • Long Battery Life: Carry out up to 16 hours of work after less than 3 hours of charging.

  • Software Suite: Comes with Emlid Flow app for iOS and Android.

Emlid Software And Services Suite

  • Emlid Flow: Mobile app for land surveying. Conduct stakeouts; configure, control and monitor your Reach receivers; manage NTRIP profiles; and log industry-standard RINEX files for PPK workflows. Free plan or paid-for option with additional features available.

  • Emlid Flow 360: Cloud-based web application that handles all fieldwork - data collection, coding, linework, and staking, and syncs with Emlid Flow. A free and a paid-for plan with additional features are available.

  • Emlid Studio: Post-process data from GNSS receivers and RTK drones. Upload RINEX and UBX logs to get precise coordinates and geotagged images. Download for free.

  • NTRIP Caster: Stream RTK corrections from your base to the rovers over the internet . Emlid Caster works with Reach and any other receivers with NTRIP support. The service is available for free and works worldwide.

  • NTRIP Caster Pro: Turn base stations into an NTRIP network. Work with Emlid NTRIP Caster with up to 5 bases and 10 rovers for free. Or upgrade to a monthly paid-for plan: Choose a plan for 20 or 50 bases.

Drone Mapping With Reach Receivers

Emlid GNSS receivers provide precise positioning in various drone mapping workflows.

  • Use Reach as a base for an RTK-capable drone.

  • Place ground control points with Reach receivers.

  • Reach module to enable RTK and PPK on a drone.

Reach As A Base Station - RTK Workflow

  1. Сreate NTRIP Mount Point: Input your mount point's details for a base and a drone.

  2. Set Up Base To Transmit Corrections: Place the base, then set up the base coordinates for RTK mode and enable RINEX logging for PPK mode in the Emlid Flow app.

  3. Connect Base To Mount Point: Insert credentials of NTRIP Caster to the Correction output settings in Emlid Flow app.

  4. Connect Drone To Mount Point: Go to the RTK Settings tab on your flight controller and insert your NTRIP credentials for the rover that you got on the Emlid Caster.

  5. Fly: Proceed with the mission.

  6. Export Data: Download the precisely geotagged photos and use them to create orthophotos.

Reach As A Base Station - PPK Workflow

  1. Set Up A Base: Place your Reach base. Enable RINEX logging for PPK mode in the Emlid Flow app.

  2. Set Up Logging On Your Drone: On your flight controller, set up a flight in GNSS mode to record the raw position information.

  3. Fly: Proceed with the mission.

  4. Export Data: Download the RINEX files from your Reach reciever, the raw positioning data, and the photos' timestamps from your drone.

  5. Process Logs: Process the files in Emlid Studio to get an accurate position for each photo.

  6. Create Your Orthophotos: Proceed to create a map with accurately geotagged photos.

Set Up Ground Control Points For Drone Mapping

  1. Place Ground Control Points: In most cases, five to 10 GCPs are required.

  2. Connect Rover To Local Base or NTRIP Provider: Using the Emlid Flow app, create a survey project and choose your local coordinate system.

  3. Collect Coordinates Of Each GCP With The Rover: The Reach receiver allows you to get centimeter-precise data.

  4. Fly: Conduct the drone mission.

  5. Export GCP from Reach in the CSV Format: Once data is collected, you can export your project in CSV, DXF, GeoJSON, DroneDeploy CSV, or ESRI Shapefiles format.

  6. Import Photos and GCP List to Emlid Studio: Upload CSV file with GCPs to your mapping software for accurate georeferencing. Create your project in mapping software.

Reach Module For RTK & PPK On A Drone

  1. Connect Reach M2 Module: Connect this module to a hot shoe port on a camera. Every time a photo is taken the camera produces a pulse on a flash hot-shoe connector which is synced to a shutter opening.

  2. Capture Data During Flight: Reach captures flash sync pulses with sub-microsecond resolution and stores them in a raw data RINEX log in the internal memory.

  3. Download Logs from Reach and Base Station: After the flight, get the RINEX logs from your airborne Reach module and a base station.

  4. Process Logs: Process RINEX files using Emlid Studio. The file is created with precise coordinates of the photos and can be used for georeferencing.
