High definition GPS for agriculture

The Outback BaseLine is a high definition GPS system for agricultural applications. It has more accuracy than standard GPS and is much more affordable than RTK GPS, says Hemisphere.

Farmers who have not yet invested in GPS guidance can use one Outback BaseLine unit to replace several sets of mechanical disc markers, usually for less than the cost of a single set. Outback BaseLine eliminates the time and effort involved in folding and unfolding, greasing and other maintenance of disc markers, while providing better accuracy and performance. It will also function reliably at night when disc markers are difficult to see.

The very portable and easy-to-use Outback BaseLine features a data transmitter, internal battery and integrated base station that can be set up in two minutes and operated at one or more temporary tripod sites at the edge of a farmer's fields. Several BaseLine Rovers or vehicle-mounted GPS receivers can be serviced using a single Outback BaseLine unit.

Outback BaseLine's five to 20 centimetre accuracy is available at approximately half the cost of RTK GPS. The innovative product's high performance is due to Hemisphere's Crescent GPS technology, including a special receiver module and proprietary chipset.

Crescent features: Coast software that enables receivers to utilize old DGPS correction data for several minutes without significantly affecting the accuracy of positioning — a big advantage during temporary signal blockages or outages; and lower power consumption which is ideal for mobile and battery operated applications.

Outback BaseLine features simple status lights, a battery monitor, recharging via an AC charger, and external power options including cigarette lighters and AC outlets. BaseLine also works well on any continent at any latitude, with no subscription fees. Its Coast software bridges the temporary gaps when signals are not available.
