This article explains how to configure a Leica GS18 GNSS receiver for use with Hovermap using Leica Captivate Simulator. Use this procedure to set up NMEA communication and antenna settings so that the receiver can communicate correctly with Hovermap during a mission.
What you will need
Hovermap unit running Emesent Cortex 3.3 or later
Emesent Aura 1.7 or later
Leica GS18 receiver
Computer with Leica Captivate Simulator installed (if no Leica CS20 field controller is available)
Procedure
Step 1: Connect to the Leica receiver with Leica Captivate Simulator
Raw scan data from a Hovermap that uses Emesent Cortex version 3.3 (or later) can only be processed in Emesent Aura 1.7 (or later).
If you don't have a Leica CS20 field controller or similar to be able to configure the receiver, or prefer to use a computer, then follow these steps:
Download and install Leica Captivate simulator from Leica website.
Connect to the Leica GS18 open WiFi connection.
Launch Leica Captivate simulator and it should automatically connect to the receiver.
Step 2: Configure NMEA Settings
Hovermap cannot detect an incorrectly set antenna height so ensure it is properly configured.
Once connected, configure the NMEA settings to make sure the Leica receiver can communicate properly with the Hovermap.
Go to (1) Settings → (1) Connections → (5) All other connections → NMEA 1
Open the NMEA settings panel and turn on "Stream NEMA"
Set the Connect using to: GS Port 1
Set the NMEA Version to: 4.0 (extended)
Use a defined talker ID can be left unchecked (turned off)
Select Messages and make sure the following are configured:
Output Rate | Messages |
|---|---|
0.20, Immediate | GGA, GSA, GST, ZDA |
1.00, Immediate | GSV |
Step 3: Configure the Tilt and Antenna Height
Navigate to: Settings → GS Sensor
Make sure that Tilt Compensation is left unchecked (turned off).
Make sure that Rover antenna is set to ADVNULLANTENNA and Antenna height is set to 0.00m
Outcome
The Leica receiver is now configured for use with Hovermap and ready to capture RTK scan data.
