The Vutog GPS Simulator provides a complete suite for all your GPS simulation needs and more. It is designed to assist in developing, testing and debugging GPS Applications and equipment working with the NMEA-0183 protocol. It can be used for testing navigation applications and equipments indoor when GPS Signal is not available for best productivity maximization.
There are seven output interfaces supported by Vutog GPS Simulator:
This product can be used with a hardware null-modem (COM port - RS232) cable, Ethernet Cable for UDP & TCP/IP, Bluetooth, Virtual COM Port and Android Mobile Devices. Multiple connections together can be created and managed from same workspace. This is very useful when you want to test multiple applications with same or different test scenarios.
Vutog GPS Simulator acts as a flexible GPS Receiver for your navigation applications which works without visible GPS satellites signals, 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. You can set any parameters of GPS Input during simulation. 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 can also be used to debug and test your Android App using GPS Gateway App. Today, 40% of Android Apps depend on inbuilt GPS Receiver of Android Mobile Phones. But testing & development of these Apps become a nightmare because Mobile inbuilt GPS receiver receives the Signal only in Open Sky.
By running Bluetooth Server under Vutog GPS Simulator, the connection between GPS Gateway App and Vutog GPS Simulator can be established over Bluetooth. GPS Gateway App connects to Vutog GPS Simulator as a Client and receives the generated NMEA Sentences or data in special format of lat=xx.xxxxxxxxxxxx, lon=xx.xxxxxxxxxxxx, alt=xx.xxxxxxxxxxxx. The GPS Gateway parses and mocks these received locations in the mobile and the mobile starts showing these locations in real time. Any app like Facebook, Google Map or your app running on this Mobile reads these locations.
Vutog GPS Simulator supports 4 input modes for GPS Device Simulation:
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.
The output NMEA Sentences can be saved to .NMEA/.TXT file or transmitted via COM port or/and TCP/IP or/and UDP or/and Bluetooth (with SPP or Without SPP) or/and using GPS Gateway App on Mobile Device over Bluetooth or/and UUID based Bluetooth Server or/and Virtual COM Port. Any program or equipment that works with the NMEA protocol will recognize these transmitted messages, created by the Vutog GPS Simulator, same 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. You can also control the speed of NMEA Generation just by a mini slider.
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 Forwarded Input Mode using Data Forward Tool can be used to forward data from Actual GPS Receiver to you applications. Using Data Forward Tool, you can multiplex Actual GPS Receiver data from one connection to many connections. Using this tool you can achieve a scenario where your original GPS Receiver supports the interface of Bluetooth & you want to forward the same data through Serial Port or TCP/IP or UDP or Virtual COM Port. You can also filter the NMEA sentences as per your need.
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 Data Forward Manager, 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.
