Positioning system has integrated antenna
The Seres is a high-performance positioning product which features a combined GPS/SBAS receiver and antenna system for precision agriculture, GIS and mapping, and other markets.
Patent for novel antenna signal splitter
CSI Wireless has been awarded a patent for its antenna splitter technology for the automotive market.
The SX-1, a PCB module that is accurate to less than 1m, is ideal for commercial and professional applications such as precision agriculture, and geographic information systems (GIS) and mapping.
Both the Evolution and SX-1 are smaller than standard business cards.
The Evolution is capable of receiving differentially corrected data from land-based beacon stations and from Space Based Augmentation Systems (SBAS) - the USA's Wide Area Augmentation System (WAAS), the European GPS Navigation Overlay System (EGNOS) and Japan's MTSAT Satellite Augmentation System (MSAS).

Vector GPS aids sailors in Volvo Ocean Race
Hemisphere GPS is supplying Vector heading systems to three of the seven sailboats competing in the Volvo Ocean Race - a seven-month, globe-circling odyssey involving some of the world's best sailors.
Receiver technology improves GPS system's accuracy
Hemisphere GPS, a designer and manufacturer of GPS products used in more than 50 countries, has announced the latest addition to its Outback family of products for agricultural guidance.
The higher-performance SX-1, besides being capable of receiving differentially corrected data from WAAS, EGNOS and MSAS, features CSI Wireless' unique Coast and e-Dif technology.
Coast enables old differentially corrected data to be used for up to 40min, when obstacles such as buildings and trees make it impossible to lock onto new data signals, without significantly degrading accuracy.
e-Dif performs a similar role, but does not require old differentially corrected data to do so.
No competing products offer this flexibility.
"The Evolution fills a gap in the market for low-cost GPS engines with redundant, on-board differential capability", said Stephen Verhoeff, President and CEO of CSI Wireless.
"It's the first affordable receiver for receiving radio beacon, GPS and SBAS signals all on one circuit board.
The SX-1 is a higher-performance GPS and SBAS engine that targets customers looking for a lower-priced and more compact module alternative to our SLX-2".
"Offering modules that support various differential services, and that achieve various performance levels, helps CSI Wireless to meet our customers' needs with a wide range of price points and functionality", Verhoeff added.
The SX-1 is the core of CSI's new SERES - a combined GPS-SBAS receiver and antenna.
Both the SX-1 and Evolution are closely patterned after CSI Wireless' highly successful SLX-2 GPS module.
The SLX-2, when equipped with CSI's SBX module, is capable of receiving data from radio beacons, from WAAS, EGNOS and MTSAT, and from subscription-based GPS satellite services such as OmniSTAR, while also featuring Coast and optional e-Dif technology.
The SLX-2 is the core of CSI's widely respected DGPS MAX, SLX-g3 and SLXg3 Combo receivers.
The SLXg3 products are recognised - in markets such as air-based precision agriculture, and increasingly in markets such as land-based precision agriculture - as the best radio beacon or differential GPS receivers available.
They are widely sold by CSI, by CSI's Satloc subsidiary, and by several other companies that integrate SLXg3s into their products.
"Our SLXg3 products have been so successful that we're now part of almost every GPS sale in the air-based precision agriculture market, and becoming the dominant player in land-based precision agriculture", Verhoeff said.
