Bosch C 80 Manual

GPS Sensor | 20Bosch Motorsport Manual_C_80 129 / 14420 GPS Sensor20.1 GPS (Global Positioning System)Space-based global navigation satellite system.GPS provides positioning, navigation, and timing services to worldwide users.GPS receiver (sensor) gives digital information about position (longitude, latitude, height),ground speed, course, and status.Two types of GPS receivers:CAN output -> Read in messages via CAN Input of C 80 (not covered here)Serial output -> Read in messages via RS232 Interface of C 80Serial Interface is characterized by:Voltage levels: RS232 is standard (+/-12 V), UART (0 V/ 5 V) needs level shifterBaud rate: 9,600 is standard for GPS, C 80 supports 1,200 to 115,200 baud. GPS Rx inter-face baud rate must match C 80 interface baud rate. C 80 Baud rate can be set with the‘GPS_BAUDRATE’ characteristic Data format: C 80 expects 8 data bits, no parity bit, 1 stopbit (8N1)20.1.1 Serial interface characterizationSerial Interface is characterized by:Voltage levels: RS232 is standard (+/-12 V), UART (0 V/ 5 V) needs level shifterBaud rate: 9,600 is standard for GPS, C 80 supports 1,200 to 115,200 baud. GPS Rx inter-face baud rate must match C 80 interface baud rate. C 80 Baud rate can be set with the‘GPS_BAUDRATE’ characteristic Data format: C 80 expects 8 data bits, no parity bit, 1 stopbit (8N1)20.2 ProtocolC 80 expects NMEA Protocol (ASCII).The following messages are decoded:Message FunctionGGA GPS fix informationGSA Overall satellite dataGSV Detailed satellite dataRMC Recommended minimum data for GPSVTG Vector track and speed over the groundOn most GPS sensors, these messages are activated in the default configuration.
