Tracks strongest signal

CSI's Hemisphere GPS division has introduced its new SBX-4 differential GPS (DGPS) beacon module. It is the newest DGPS beacon module in Hemisphere GPS' SBX series.

The SBX-4 is designed for use by original equipment manufacturers (OEMs) who need to integrate a versatile precision beacon receiver module into their product. The SBX-4 DGPS beacon module features: a dual channel design allowing for strongest signal or new closest station (database) tracking, a ceramic filter blocks out-of-band signals to optimize reception, reverse compatibility simplifies integration with products based on the existing SBX-2 and SBX-3 modules, a boot loader ensures firmware upgrade reliability, dual series ports to accommodate separate RTCM and NMEA communications, certified IEC 61108-4 and RoHS compliant.

CSI's Hemisphere GPS division has also introduced its new Crescent R100 series DGPS receiver. The Crescent R100 is the ideal solution for professional mapping, guidance and navigation applications. It joins the Crescent A100 Smart Antenna, Outback S2 and Outback BaseLine as the latest development to take advantage of Hemisphere's powerful Crescent technology.

Powered by Hemisphere's Crescent technology, the R100 series features: 12 channel L1 GPS receiver with code and phase measurements, reliable DGPS positioning with less than 60cm accuracy and with an output rate of up to 20 times per second, especially fast start-up and signal re-acquisition times, simple user interface and status lights allow easy configuration and receiver monitoring, available with several options for DGPS sources including satellite based augmentation systems (WAAS, EGNOS), radio beacon and OmniStar corrections, compatible with Hemisphere's exclusive L-Dif technology for applications requiring accuracy less than 20cm, and radar simulated pulse output provides accurate ground speed.

These portable and versatile receivers also feature Hemisphere's exclusive Coast and e-Dif technologies. Coast software enables Hemisphere GPS receivers to utilize old differential GPS correction data for 40 minutes or more without significantly affecting the quality of positioning. When using Coast, the user is less likely to be affected by differential GPS signal outages due to signal blockages, weak signals or interference. No competing products offer this flexibility.

e-Dif technology enables Hemisphere GPS receivers to achieve DGPS quality positioning accuracies without the need for a differential signal. It is ideal for locations where other differential services are limited or expensive. The Crescent R100 series will replace the SLXg3 and MAX series of receivers.
