  1. GPS Communication Interface Thomas Walter Will Hovhannessian

  2. GPS Communication Interface • Very impressive technology (Localize anything on earth) • Origines : U.S Army (24 satellites around earth) • Applications : • War • Navigation (cars, boats, planes) • Agriculture • 3 satellites are needed to have a localisation

  3. The NMEA Protocole • National Marine Electronics Association • Data protocol for communications between marine instrumentation • NMEA sentences are all ASCII • Sentences begin by a $ • Exemple : $GPAAM,A,A,0.10,N,WPTNME*43

  4. Java • Good language to use the NMEA protocole • Realisation of a Parser in java • Emulation of a gps by a XML file. • Parser is used to parse this XML file in order to collect the information of the localisation (lattitude, longitude,altitude…)

  5. C# Program • Studying a program (C# language) used for GPS interface treatment • Main goal : communicate with the GPS • Collect continu informations=synchronisation problem • Using NMEA protocol
