The Vutog GPS Simulator provides a complete suite for all your GPS simulating needs and more. It is designed to assist in developing, testing and debugging programs and equipment working with the NMEA-0183 protocol. It can also be used for testing navigation applications and equipment indoor when GPS Signal is not available for best productivity maximization. In addition to this, this product can also used to test GPS Device and its output correctness. 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 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. 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.
