Hemisphere GPS has introduced the LX-1 a new L-Band OmniSTAR compatible differential GPS (DGPS) receiver board. The LX-1 improves position accuracy of Hemisphere GPS’s Crescent® Receiver Technology to sub-meter measurement. This new solution is one of many differential options offered by Hemisphere GPS.
Hemisphere GPS’ LX-1 tracks L-Band differential signal corrections through OmniSTAR to improve stand-alone GPS solutions. It provides a reliable differential GPS option as OmniSTAR satellite corrections are available on most land areas of the world.
The LX-1 includes subscriber access so OmniSTAR can activate subscriptions remotely via satellite uplink. While it automatically tracks the best available satellite broadcast the user also has the option to manually set which satellite to track. Additionally the LX-1 is supported by Hemisphere GPS’s COAST™ technology to ensure accuracy is maintained during temporary loss of the differential signal.
Hemisphere GPS’ LX-1 is designed for use by Original Equipment Manufacturers (OEM) that want to augment Crescent GPS with OmniSTAR differential capability. It is the same size as Crescent OEM boards and directly compatible for convenient integration. Hemisphere GPS has integrated this new technology into several Crescent receiver models such as the R120 R121 and R130 DGPS receivers.
“Our new LX-1 Board provides increased access to differential signals and improves the accuracy of our Crescent GPS receivers” said Steven Koles president and CEO of Hemisphere GPS. “This additional differential solution further enables accurate and reliable GPS positioning particularly in regions where other differential signals are not accessible” he said.
The LX-1 joins Hemisphere’s Crescent VS100 and V100 positioning and heading receivers which update the company’s Vector-Pro technology.
The VS100 and VS110 “Vector Sensor” products provide precise heading and positioning systems incorporating the company’s Crescent Technology. The systems provide an affordable and robust heading and positioning solution for machine control and marine navigation applications including dredging and hydrographic surveying.
The Crescent VS100 Series GPS Compass delivers the performance necessary to replace traditional gyrocompasses and other precision heading sensors at a fraction of the cost.
“Crescent VS100 represents an innovative GPS advancement that allows us to replace traditional heading solutions” said Steven Koles.
Hemisphere GPS’ Crescent Receiver Technology supports two antenna inputs. Crescent VS100 computes and outputs heading and either pitch or roll angles by processing the data between the two antennas using a single GPS receiver. The receiver features status lights with a menu and display system simplifying product configuration. The receiver can be installed near the operator while its two antennas can be mounted remotely. With a suitable distance between the two antennas Crescent VS100 computes heading solutions with up to 0.1 degree accuracy and positioning within 60 cm.
Crescent VS100 offers several differential options including SBAS (WAAS EGNOS) e-Dif and radio beacon (VS110 model). Hemisphere GPS’s Coast technology is also included in order to maintain sub-meter positioning for 40 minutes or more after loss of differential signal. An integrated gyro within the Crescent VS100 receiver maintains heading for up to three minutes after loss of GPS signals.
