HS4 MkII- Primary GPS with Digital Barometer

and MotionSense

IstarGPS is specifically designed for  large vessels and performance yachts seeking ultra fast speed and course data with a high performance receiver and the most versatile interfacing on the market.  We also included a precision Barometer sensor, because we can!


IstarGPS uses a cutting edge Ublox 50 channel WAAS/EGNOS GPS chipset which produces speed and course data using MotionSense technology.  MotionSense provides extraordinarily responsive speed-over-ground and course-over-ground data by using Doppler of the satellite carrier wave.


The HS4 MkII is part of a new generation of high correlator super sensitive receivers.   Excellent reception in the worst conditions (or antenna locations).

The HS4 MkII is the heart of your position data distribution. With four independent NMEA output ports and a USB port, there is no need for external amplifiers - drive 12 or more listeners directly at bauds to 115k.  IstarGPS also broadcasts NMEA data via Ethernet UDP - up to 40 ports!  Compatible PC applications no longer need NMEA data on a USB or serial port!
