GPS module is OEM positioning system

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

Hemisphere GPS, a designer and manufacturer of GPS products used in more than 50 countries, has developed a new heading sensor module for original equipment manufacturers (OEMs) that features the company's high-performance Crescent GPS technology.

"The Crescent Vector OEM module is a dynamic navigation solution at a very affordable price", said Rick Heiniger, President of Hemisphere GPS, a wholly owned subsidiary of CSI Wireless.

"It's well-suited to any application requiring accurate heading and positioning".

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.

The integration of Hemisphere's patented Crescent GPS technology enables the Crescent Vector OEM module, in comparison with competing products, to deliver higher update rates, noise-reduced raw measurements, more memory, more processor capacity, lower power consumption, and more advanced applications and sophisticated configurations.

Crescent technology also enables the module to simultaneously employ multiple front ends - enabling tighter coupling of measurements from separate antennas for use with heading-based products.

Users will achieve excellent accuracy and stability, due to Crescent's more accurate code phase measurements, improved multipath mitigation, and fewer components.

The Crescent Vector OEM module offers maximum flexibility to OEMs and integrators by enabling them to choose their appropriate power supply and communications translation.

In addition to its discrete Crescent GPS components, the module integrates a single-axis gyro and a tilt sensor onto a small form factor.

Its heading accuracy ranges from 0.1 degrees (RMS) at 2.0m antenna separation to 0.25 degrees (RMS) at 0.5m antenna separation.

It provides heading and positioning updates of up to 20Hz, and delivers positioning accuracy of 200mm 95% of the time when used with Crescent's L-Dif differential GPS (DGPS) receiver product, and 500mm 95% 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 enables Hemisphere receivers to use old DGPS correction data for 40min 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.
