S3 User Guide 67 PN 875-0196-000 Rev C1
Appendix B: Frequently Asked Questions
Q: How does weather affect the GPS signal?
A: Rain, sleet, snow, thunderstorms, and wind normally do not affect the GPS signal.
Lightning is not a problem unless it is a close strike—direct lightning strikes will
damage the S3. Snow and ice accumulation on the antenna may also cause problems.
Q: How do power transmission lines affect the GPS signal?
A: Normally, high voltage power transmission lines do not affect the GPS signal at all.
About Outback S3
Q: What's the difference between Steering Guide and Current Position?
A: Steering Guide calculates the nose heading for you to steer to correctly follow the
intended path. Current Position only reports the distance left or right of the intended
path. You drive using the Steering Guide and check results using Current Position.
Q: Can I use S3 as a receiver for other uses?
A: Yes. S3 accommodates NMEA 0183 serial and NMEA 2000 CAN communication
protocols. Contact your Outback Guidance dealer for the latest compatibility list.
Q: How long does it take S3 to obtain a usable signal?
A: It normally takes 1 - 3 minutes. S3 first acquires the GPS signal (“3d” appears on
the GPS tab). Next, S3 acquires the DGPS correction (“3D” appears on the GPS tab).
S3 takes 10 minutes to generate e-Dif corrections and, for RTK corrections, it may take
15 minutes of consistent corrections to establish an RTK lock. The vehicle can be in
motion during this process.
Q: Does the S3 have memory?
A: S3 records all movement as long as guidance is on. When you pause a job using
either the Run/Hold Floor Switch or the Apply control button, no data is recorded. S3
can record up to 30 hours of data for a single job. When the job is finished, S3
automatically saves the job data. Historical data for each job is collected and stored on
the system. You can import, export, or erase all data on the Job screen.
Q: How do I erase memory?
A: To erase the memory in the S3, touch or click the Jobs button on the Job tab. The
Manage Jobs screen appears. Select the job to delete and touch the Delete button. To
delete all the recorded job data touch the Delete All button. Touch the Yes button to
continue or touch the No button to cancel.
Q: What is Straight Guidance?
A: In straight guidance mode S3 generates straight, parallel lines. S3 locks on the
closest line based on the first A-B pass and the entered swath width and then records
the actual movement over those lines while guiding. You can generate a new A-B line
at any time with S3. You can also use straight guidance to create circular (pivot) rows.
Q: What is Contour Guidance?
A: In contour guidance mode S3 records all movement as the machine moves around,
unless you pause S3 using the Run/Hold Floor Switch or the Apply control button.
During the initial pass, no guidance is given. When you make a second pass and
subsequent passes, S3 guides along the previous pass.
