3. User s Manual USB GPS Receiver Version 2 0e 1 Introduction 1 1 Overview This product Smart GPS Receiver is a total solution GPS receiver designed based on SIRF Star IIl Architecture This positioning application meets strict needs such as car navigation mapping surveying security agriculture and so on Only clear view of sky and certain power supply are necessary to the unit saves critical satellite data by built in backup memory With low power consumption the device tracks up to 20 satellites at a time re acquires satellite signals in 100ms and updates position data every second Trickle Power allows the unit operates a fraction of the time and Push to Fix permits user to have a quick position fix even though the receiver usually stays off 1 2 Features This product provides a host of features that make it easy for integration and use 1 SiRFstarlll chipset with embedded ARM7TDMI CPU available for customized applications in firmware 2 High performance receiver tracks up to 20 satellites while providing first fast fix and low power consumption 3 Differential capability utilizes real time RTCM corrections producing 1 5 meter position accuracy 4 Compact design ideal for applications with minimal space 5 A rechargeable battery sustains internal clock and memory The battery is recharged during normal operation 6 User initialization is not required 1 3 Technology specifications 1 3 1 Physical Dimension Single cons
4. as been calculated information about valid position velocity and time is transmitted over the output channel The device utilizes initial data such as last stored position date time and satellite orbital data to achieve maximum acquisition performance If significant inaccuracy exists in the initial data or the orbital data is obsolete it may take more time to achieve a navigation solution The device Auto locate feature is capable of automatically determining a navigation solution without intervention from the host system However acquisition performance can be improved as the host system initializes the device in the following situation 1 Moving further than 500 kilometers 2 Failure of data storage due to the inactive internal memory battery 2 2 Navigation After the acquisition process is complete the device sends valid navigation information over output channels These data include 1 Latitude longitude altitude 2 Velocity 3 Date time 4 Error estimates 5 Satellite and receiver status The device sets the default of auto searching for real time differential corrections in RTCM SC 104 standard format with the message types 1 5 or 9 It accomplishes the satellite data to generate a differential DGPS solution The host system at its option may also command the device to output a position whenever a differential solution is available 3 USB Driver 3 1 Installation Connect the device USB connector to computer
