Vutog GPS Simulator works in two operational modes for each connection type (COM Port and TCP/IP) –
(a) GPS Sender (generator)
(b) GPS Receiver
In GPS Sender Mode, Vutog GPS Simulator acts as a GPS Receiver which works without visible GPS satellites, thus it's much more efficient when used indoors and provides significant productivity. It gives out GPS data (reception quality, speed of relocation, position, and satellite constellation) based on the NMEA-0183 protocol of chosen version. NMEA Sentences can be selected for GPS Simulation based on your need.
More important, it works in tracking mode. That is, you just need to select Start Point and End Point before starting GPS simulation. The Vutog GPS Simulator starts generating NMEA Sentences with all data by auto calculation for the object movement from Start Point to End Point.
For example, for $GPRMC sentence, it auto calculates:
? the True Course based on Start Point and End Points selections
? UTC Time based on system time
? the distance travelled based on speed selected per hour
? the latitude and longitude for current point after travelled distance
? magnetic variation of same latitude and longitude
? depicts it on map
? And generates the $GPRMC.
The output NMEA Sentences can be saved to .NMEA/.TXT file or transmitted via COM port or/and TCP/IP. Any program or equipment that works with the NMEA protocol will recognize transmitted messages, created by the Vutog GPS Simulator, as data from a real GPS receiver. A certain amount of parity errors (CRC) can be introduced in the generated protocol for testing consistency of operation in navigation programs.
The Vutog GPS Simulator in Sender Mode supports several operation input modes (Map Input, Log files Playback and None), and it can give out output data to a COM port, save to a file or broadcast via TCP/IP. The saved file can be re-played providing an opportunity for creating repeatable test scenarios (for example, for regression testing), which would be difficult to do with an actual GPS receiver.
In GPS Receiver mode, the product listens to connections (COM Port and TCP/IP), receives data coming from connected devices/applications and displays it. The received data can be logged by Logger utility if required and can be played back in Sender Mode. In this mode, it works more than a HyperTerminal utility for any GPS Device. You can log the output of GPS devices and analyze it for its corrections. This way, this product can also be used for a GPS Device Testing and Development.
Apart from this, it also provides certain utilities like CRC calculator, NMEA Sentence Selector and Logger. These are very useful while doing any GPS related development and testing work.
