This guide explains the 3 RTK and GNSS correction sources that can be used for Autosteering.
1. Introduction to Correction Sources 0:01
- Overview of three correction sources available for the HD408 system:
- PPP GNSS (Precise Point Positioning, Global Navigation Satellite System )
- CORS network (Continuously Operating Reference Stations) or other cellular RTK networks
- Radio RTK base station
2. Accessing the Menu 0:09
- Click on the gray Radio tab at the top of the screen to access correction source options.
3. Using PPP GNSS (Option 1) 0:31
A convenient option that uses precise satellite signals and clock corrections derived from a global network of reference stations. No subscription or additional equipment required.
- To use PPP GNSS:
- Click 'Auto Search' and then 'Search' to load PPP options.
- Choose E6 HAS (do not select B2b, as it is not compatible in the US).
- Press 'Reset GNSS' to restart the connection
- On the main screen, the satellite count will return to ‘0’ and then start climbing
Best for a reliable, precise connection. Requires an existing base station or CORS/cellular RTK network account.
- For CORS network or RTK base station:
- Click 'Manual Select' tab at the top of the screen
- For CORS network, select 'Cors Station' and input settings and license information.
- For Radio station, select 'Radio Station' and input base station settings.
- Press 'Reset GNSS' to restart the connection
- On the main screen, the satellite count will return to ‘0’ and then start climbing
- As stated above, after selecting any correction source or switching between sources, press 'Reset GNSS' to reconnect to reset the connection.
- The system will start at 0 satellites and should reach 28 to 30 for optimal performance.
**Important Notes** 2:02
- Confirm RTK is ‘FIXED’ before starting calibration or operations for successful auto steer.
- Connect to a correction source in a large open area away from trees or buildings for best results
