Hemisphere GPS has introduced a new heading sensor module for Original Equipment Manufacturers (OEMs) that features the high performance Crescent GPS technology.

The Crescent Vector OEM module, a printed circuit board, is a complete GPS compass and positioning system designed primarily for the marine market but also very applicable for other markets including agriculture and machine control.

In addition to its discreet Crescent GPS components, the module integrates a single-axis gyro and a tilt sensor. Its heading accuracy ranges from 0.1 degrees (rms) at 2.0 metre antenna separation to minus 0.25 degrees (rms) at 0.5 metre antenna separation. It provides heading and positioning updates of up to 20Hz, and delivers positioning accuracy of 20cm 95 percent of the time when used with Crescent's L-Dif differential GPS (DGPS) receiver product, and 50cm 95 percent of the time when used with WAAS (Wide Area Augmentation System) DGPS

The Crescent Vector OEM module also features Hemisphere's exclusive COAST software that enable Hemisphere receivers to utilize old DGPS correction data for 40 minutes or more without significantly affecting the quality of positioning. When using COAST, the Crescent Vector OEM is less likely to be affected by differential signal outages due to signal blockages, weak signals or interference.

The Outback S2 builds on the success of Hemisphere's Outback S guidance system. Integrating the new Crescent receiver technology into the Outback S2 enables it to achieve a 50 percent increase in accuracy and performance over previous models, says the company.

Crescent technology also enables the Outback S2 to achieve faster start-up and GPS signal acquisition times; improved update rates of 10Hz; lower power consumption and radar-simulated ground speed output.

The Outback S2 is an easy-to-install, easy-to-use, low cost guidance system featuring a robust 10Hz differential GPS WAAS (Wide Area Augmentation System) receiver and Steering Guide. It enables operators to drive straight rows, with no skipped areas and minimal overlaps, to achieve major cost savings in fuel, fertilizer and virtually all other production input costs.
