Portable, Dual-Frequency GPS RTK Solution. The A220™ and A221™ Smart Antennas offer versatile, portable solutions with centimeter-level accuracy powered by the Hemisphere GPS Eclipse™ dual-frequency GPS receiver technology in rugged, all-in-one enclosures.

Complete your work quickly and accurately with the R100™ Series DGPS receiver. Rely on consistent sub-meter performance with standard SBAS differential and Hemisphere GPS’ exclusive COAST™ technology that maintains accuracy during temporary loss of differential signal.

The R100 Series offers many differential correction options for various environments and worldwide coverage. The simple interface and solid construction make the R100 Series the ideal solution for professional mapping, guidance and navigation applications.

Experience superior navigation from the accurate heading and positioning performance available with the V101™ Series GPS compass. The Crescent® Vector™ II technology brings a series of new features to the V101 series including heave, pitch and roll output and more robust performance.

The rugged enclosure combines Hemisphere GPS’ Crescent Vector II board and two multipath-resistant antennas for portability and simple installation. The half-meter length smart antenna mounts easily to a flat surface or pole. The stability and maintenance-free design of the V101 replaces traditional gyrocompasses at a fraction of the cost.

Precise applications demand the heading and positioning performance of the VS101™ series GPS compass. Ideal for professional machine control and navigation applications, the VS101 and VS111™ delivers reliable accuracy at significantly less cost than competitors’ products or traditional methods.

The Crescent® Vector™ II technology brings a series of new features to the VS101 series including heave, pitch and roll output and more robust performance. The VS101 Series receiver, with its display and user interface, can be conveniently installed near the operator. The two antennas are mounted separately and with a user-determined separation to meet the desired accuracy. The VS101 uses SBAS (WAAS, EGNOS, MSAS, etc.) for differential GPS positioning. The VS111™ includes both SBAS and radio beacon differential GPS positioning options.

A New Standard of Performance Crescent® receivers feature Hemisphere's exclusive application-specific integrated circuit (ASIC) computer chipset technology. They establish a new benchmark for performance, versatility and value. They deliver higher update rates, noise-reduced raw measurements, more memory and higher processor capability, to enable more advanced applications and sophisticated configurations.

Crescent receivers also simultaneously employ multiple front ends - enabling tighter coupling of measurements from separate antennae for use with heading-based products. Users will obtain excellent accuracy and stability, due to Crescent's more accurate code phase measurements, multipath mitigation improvements, and fewer discrete receiver components. The first Crescent receiver to employ the Hemisphere ASIC is the Crescent OEM module - an integrated circuit board for Original Equipment Manufacturers (OEMs). Since then, Hemisphere has introduced the Crescent Vector OEM module – an integrated circuit board for OEMs specializing in products for Marine applications as well as Agriculture and “Machine Control” applications.

Crescent technology is the front-end component in a variety of high-performance innovations that Hemisphere GPS is developing for several increasingly popular applications including agricultural guidance and machine control, marine navigation and GIS & mapping. The technology can achieve update rates of as much as 20 Hz - making it ideal for these applications.

Dual Frequency GPS Board Develop precise applications with superior performance and versatility of Hemisphere GPS’ Eclipse™ OEM board. Eclipse receiver technology delivers reliable dual-frequency GPS solutions through Hemisphere GPS’ exclusive techniques for reducing code measurement noise and mitigating multipath signals.

Eclipse fits a wide range of applications with support for a variety of differential GPS solutions including RTK, OmniSTAR® (HP and XP) and SBAS (WAAS, EGNOS, etc.). Integration is simplified with Eclipse multiple serial and USB ports and upgradeable firmware for establishing the desired configuration and quick access to new features. Based on Hemisphere GPS’ successful Crescent® L1 GPS technology that incorporates exclusive techniques for reducing code measurement noise and mitigating multipath signals, Eclipse delivers reliable centimeter-level accuracy. The superior performance and versatility of Hemisphere GPS’ Eclipse board allows OEM customers to integrate it into a wide variety of precise applications including navigation and GPS machine control. Depending upon the application, Eclipse users can record and post-process GPS data or choose from several differential solutions including Real-Time Kinematic (RTK), OmniSTAR (HP/XP) and SBAS (WAAS, EGNOS, etc.).

As an affordable dual-frequency solution, Eclipse receiver technology offers several other advantages to the OEM integrator including integrated L-Band tracking that powers down when not in use, multiple serial and USB ports, and upgradeable firmware.

The World's Most Popular DGPS Beacon Module Provide a reliable source of differential corrections with the SBX-4™ Radiobeacon Board that augments a separate GPS receiver with free accuracy improving correction data from networks of beacon stations located throughout the world. With dual-channel architecture to ensure the best station is always being decoded, the SBX-4 delivers high performance reception and a wide range of functionality, including the capability to be tuned to signal strength or station distance.

The SBX-4 outputs the industry standard RTCM SC-104 format accepted by differential-ready GPS receivers and can be also configured and monitored with NMEA 0183 protocol.
