• • • AIRSPY Airspy HF+ Airspy HF+ is a paradigm shift in high performance HF radio design. Like most high-end HF receivers, the HF+ uses very high dynamic range ADC’s and front-ends. ![]() HI-206 is a GPS receiver with RS-232 interfaces and USB connector and built-in active antenna for high sensitivity to tracking signal. HI-206 is very small in size and well suited to system integration and users who use any kinds of mobile devices, such as, Smartphone, PDA, notebook PC, iPad, etc. The HI-206 USB GPS receiver is a high sensitivity 20 channel GPS. It is suited to a wide variety of applications, such as car navigation, personal navigation, marine navigation etc. It simply plugs into a USB capable device such as laptop, or tablet PC running with suitable mapping or routing software. But unlike the current offerings in the market, it also brings more frequency agility by using high performance passive mixers with an excellent polyphase harmonic rejection structure. No external band aid filters are required like the lower end HF receivers, which makes it the ideal companion for light portable high performance operation. Both the architecture and level of integration achieved in this design allow us to bring top performance reception at a very affordable price Specfications: • HF coverage between 9 kHz. 31 MHz • VHF coverage between 60. 260 MHz • -140.0 dBm (0.02 µV / 50 ohms at 15MHz) MDS Typ. At 500Hz bandwidth in HF • -141.5 dBm MDS Typ. At 500 Hz bandwidth in FM Broadcast Band (60 – 108 MHz) • -142.5 dBm MDS Typ. At 500 Hz bandwidth in VHF Aviation Band (118 – 136 MHz) • -140.5 dBm MDS Typ. At 500 Hz bandwidth in VHF Commercial Band (136 – 174 MHz) • -140.0 dBm MDS Typ.

INTRODUCTION OF GPS USB DRIVER FILES.29 B. WINDOWS 98 INTERFACE.32 1. Install GPS USB Driver. • HI-204 -USB WATERPROOF Ultra High Sensitive USB GPS Receiver. • General description of what GPS is and how it works. GPS (Global Positioning System) is the only system today able to show you your exact position on the Earth anytime, in any weather, anywhere. GPS satellites, 24 in all, orbit at 11,000 nautical miles. • Although GPS was designed for military use, many thousands of civilians make use of it. The satellites actually broadcast two signals, one is only for military use, and the other can be used by both military and civilians. Since GPS is passive (you only need to receive the signal), there are no restrictions on who can use the signal available to civilians. HI-204 -USB Series Introductions HI-204 -USB is a GPS receiver with USB interfaces and built-in active antenna for high sensitivity to tracking signal. HI-204 -USB is well suited to system integration and users who use any kinds LaptopPC. It satisfies a wide variety of applications for car navigation, personal navigation or touring devices, tracking and marine navigation purpose. • USB port For notebook PC use: HI-204 -USB connect with a LaptopPC USB port. • SECTION 1 INTRODUCTION 1.1 OVERVIEW Fast Acquisition Enhanced Sensitivity 20 Channels “All-In-View” Tracking GPS Sensor Module The receiver continuously tracks all satellites in view and provides accurate satellite positioning data. The HI-204 -USB is optimized for applications requiring good performance, low cost, and maximum flexibility; suitable for a wide range of OEM configurations including handhelds, sensors, asset tracking, PDA-centric personal navigation system, and vehicle navigation products. • 1.2 Features • 20 parallel channel GPS receiver • 4000 simultaneous time-frequency search bins • SBAS (WAAS, EGNOS) support • -159dBm tracking sensitivity •,,,,,,* Example: $GPGLL,2447.2073,N,,E,104548.04,A, A*65. • Field Example Description 2447.2073 Latitude in ddmm.mmmm format Leading zeros transmitted Latitude hemisphere indicator, 'N' = North, 'S' = South Longitude in dddmm.mmmm format Leading zeros transmitted Longitude hemisphere indicator, 'E' = East, 'W' = West 104548.04 UTC time in hhmmss.ss format, 000000.00 ~ 235959.99 Status, 'A' = valid position, 'V' = navigation receiver warning. • 4.1.4 GSA - GPS DOP AND ACTIVE SATELLITES GPS receiver operating mode, satellites used for navigation, and DOP values.
