Vutog Releases GPS Simulator 2.2

Jan. 21, 2013 - PRLog -- This product can be used with a hardware null-modem (COM port - RS232) cable or Network for TCP/IP. Multiple connections together can be created and managed from same workspace. This is very useful which you want to test multiple devices with same or different test scenarios.

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, satellite constellation and more) based on the NMEA-0183 protocol of chosen version. Three different input modes of it provide you the maximum flexibility to configure NMEA Sentences in the way you want. NMEA Sentences can be selected for GPS Simulation based on your need.

Vutog GPS Simulator supports 3 input modes for GPS Device Simulation -

1.          World Map Input mode

2.          Log files playback input mode (Advanced NMEA Player)

3.          None Input mode

In World Map Input mode, 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:

ü          the True Course based on Start Point and End Points selections

ü          UTC Time based on system time

ü          the distance travelled based on speed selected per hour

ü          the latitude and longitude for current point after travelled distance

ü          magnetic variation of same latitude and longitude

ü          depicts it on map

ü          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 Log files playback input mode provides a lots of high end capabilities to replay the stored log files. You can view analyze the tracking path (the path of object moved) on XY Plot Graph and World Map. The latitude & longitude can be viewed and plotted into Nautical Miles (NM), miles, kilometer and meter on XY axis. You can see the NMEA File (replay log file) statistics like total number of NMEA sentences, total number of $GPRMC, total number of $GPGSA etc.

Replay speed controller gives high flexibility to control the speed of NMEA replay just like a MP3 player - like 1 NMEA per Sec, 10 NMEA Per Sec or maximum speed.

This capability of saved file re-playing provides an opportunity for creating repeatable test scenarios (for example, for regression testing), which would be difficult to do with an actual GPS receiver. Also, the track of any object movement stored in a standard NMEA file can be seen on XY Graph Plot and Map.

The None Mode provides lots of capabilities to play with NMEA sentences. You can type, load and send the NMEA to TCP/IP and COM Port. You can select loop for a repetitive replay. You can also mention the delay in milliseconds among all replay passes.

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.

Advanced Docking GUI and Multithreaded environment of Vutog GPS Simulator provides a full control over GPS debugging and Testing. N number of connections can be configured from a single Vutog GPS Simulator and broadcasts the same NMEA to all connections or each connection can work separately to provide simulation to different GPS Devices at same time.Features overview of Vutog GPS Simulator 2.2.0.104 by Simmi. http://www.youtube.com/watch?v=oJditzZy0ZM
