If correctly connected, data will now be displayed in the u-center views. - To configure the device, open: View -> Configuration View - NAV5 view: dynamic platform model can be set to portable, airborne (50km altitude limit) or pedestrian. Default: portable. - PM view: settings of interest: peak current reduction (p.25 in datasheet), EXTINT pin control high keeps awake. - MSG: DTM off, GBS off, GGA on, GLL off, GRS off, GSA off, GST off, GSV on, RMC off, VTG on, ZDA off ==== Used NMEA messages ==== * $GPGGA,hhmmss.ss,Latitude,N,Longitude,E,FS,NoSV,HDOP,msl,m,Altref,m,DiffAge,DiffStation*cs<CR><LF> * $GPGSV,NoMsg,MsgNo,NoSv,{,sv,elv,az,cno}*cs<CR><LF> * $GPVTG,cogt,T,cogm,M,sog,N,kph,K,mode*cs<CR><LF> * ex: $EIGPQ,RMC*3A (poll an NMEA message) -> p.58 in ubx datasheet ===== Navigation concept ===== * Waypoint manager: Remotely updateable waypoint store (home is by definition the first waypoint of the table ===== References ===== * MAV nav http://infoscience.epfl.ch/record/187596/files/Report_final.pdf * Protocols: http://www.u-blox.ch/images/downloads/Product_Docs/u-blox6_ReceiverDescriptionProtocolSpec_%28GPS.G6-SW-10018%29.pdf * useful NMEA frames (http://www.catb.org/gpsd/NMEA.html#_aam_waypoint_arrival_alarm): * GGA * APA * AAM * NMEA parsing lib: https://github.com/cloudyourcar/minmea (requires -std=c99 -Dtimegm=mktime) octanis1_gps.txt Last modified: 7 years agoby sam
