Outback Gps light bar

ratskinner · Mar 24, 2021

I am looking at a used outback gps s2 light bar and I like to know what people think of it and how well it does at keeping the row close together.
I have heard that some gps my be off by a foot or 2 .That would not make for good row spacing .

General gps like a phone or tablet can be off 12 feet, and can wander a bit during the day or year to year can wander quite a bit. Really nice to find an address or a field, or to circle a field for approximate size, etc. but not really helpful for close work.

Waas gps is better, it can be off a 2-3 feet, and it too can wander from year to year. It gives a good reference for tillage or spraying, but isnt real accurate for planting and such.

RTK is really spendy, and needs a local ground transmitter that likely costs you a yearly license fee, and can be within 3 inches or less year to year to year. Thry use that local non-moving reference point to keep the slightly wandering satellites honest.

I think a lot of light bars are waas. Might be helpful for planting, but not going to be accurate all day long....... Hope someone who knows more chimes in.

The Trimble systems have always said waas is within 6 inches the next level omnistar is 2-4 inches but requires a subscription and rtk is within or less than a half inch pass to pass and year to year. RTK requires a base station within range of a radio. That can come in different forms,a subscription, or your own portable or permanent station. All of which are a substantial investment cost to upgrade from the basic waas signal. The biggest problem with a waas system is the satellite drift that happens during the day most systems have an offset feature that allows you to manually adjust the line to help with this. I'm going to assume outback is similar to Trimble since they are sold in the same market for the same purpose
