Setup the Reach RS2

A GNSS base station is necessary to produce an accurate result from the R2A. Here's how to set up for optimal results:

1. Ensure No Electronics Nearby

Keep all electronics at least 6 feet (2 meters) away from the base.

Electronic devices may produce RF noise that could affect the reception of the GNSS signal.

2. Clear Sky View

The base station needs to have a clear sky view 30 degrees above the horizon. There should be no obstacles that could block the view like buildings, trees, cars, humans, laptops, etc.

Setting up

The picture on the left demonstrates desirable conditions for the base location such as:

  • open field
  • top of the hill

The picture on the right  is an example of undesirable surrounding conditions such as

  • reduced view of the sky
  • possible obstructions, buildings
  • nearby vegetation
  • indoors 

3. Placing Reach RS2

Place the Reach RS2 on  the ground and make sure it's leveled as shown in the photo below.

  • If you are setting up base coordinates, place the Reach RS2 precisely above the marked point on the tripod and leveled.

Measuring the base

  • Antenna height is measured as the distance between the mark and the antenna reference point (ARP).
  • For Reach RS2, consider the antenna height as the distance between the mark and the bottom of Reach RS2 (h in the figure above) plus 134 mm.

4. Reach RS2: First Start

Watch the video below to update the RS2 firmware.

5. Turn on Reach

Press and hold the power button until all the LEDs light up. When the loading animation stops, Reach RS2 has booted up and is fully available.

6. Connect to Reach via Wi-Fi and open ReachView

Make sure that Reach is broadcasting Wi-Fi: the LED must be solid white. Connect to RS2 like to a usual Wi-Fi network. By default login and password are these:

Login Password
reach:xx:xx emlidreach

Check the Wi-Fi LED. Solid blue network LED stands for successful connection to a Wi-Fi network. If it's solid white again, that means Reach switched back to hotspot mode. In this case check that you've entered the information for your Wi-Fi network correctly and try again.

ReachView3 App

  • Download the app for iOS or Android. Get it from the App Store, Google Play or scan the QR code on the sticker on top of Reach..
Google Play App Store
Android ReachView 3 app [60 MB] iOS ReachView 3 app [74.7 MB]
  • Open ReachView app. In ReachView you'll see a list of Reach receivers in the same Wi-Fi network as your device. Tap the one you want to work with.

7. Setup the Reach RS2

Configure this once and always use these settings.

  • Connect to Reach RS2 and open RTK Settings tab.
  • Set Positioning mode to Static.
  • Pick each of the satellite systems.
  • Set the Update rate at 1 Hz.
  • DO NOT CHECK "THIS  LOG IS FOR OPUS" BOX

Enable Logging

  • Open the Logging tab.
  • Set Raw data to Rinex 3.03 and toggle on
    • RINEX is a industry standard for raw data. The log contains GNSS observations from the receiver without calculation of accurate coordinates.

Watch video below for reference only. Use the settings listed above.

Downloading

After completing the survey, save logs to your Mac, Windows, Linux or mobile device.

  • Open the Logging tab
  • Turn off toggles to stop recording.
  • Find your logs below in the Logging tab.

You can see the recording date and time. There are two buttons on the right side of each log:

  • blue arrow button saves it.
  • red garbage can button deletes it.

Storing the base position

If you want to reuse the determined base location:

  • Carefully mark physical position on the ground
  • Save coordinates to manual using the button in the Base Coordinates section of the Base mode tab
  • When using this position next time, accurately place the base station over the mark
  • Enter the recorded coordinates manually in ReachView 3
