Page 5: Nmea Default Output Messages
NMEA Manual based on MediaTek chipset - Manual 1 NMEA default output messages IT500 series receivers support standard NMEA0183 messages. In the default configuration, output messages are GGA, RMC, GSV and GSA messages. The receiver can be configured to have a user defined set of output messages, by command PMTK314 as described in chapter 2.12. Output messages are utilized in Fastrax Workbench 5 to visualize the GPS/GNSS data. -

Page 32: Fix Valid Flag
NMEA Manual based on MediaTek chipset - Manual 5 FIX Valid Flag This chapter concerns only the UP500 antenna module. It is important to note that the current UP500 receiver firmware output position coordinates in RMC and GGA messages even if the position is flagged as invalid in the NMEA RMC message. This is contrary to most other GPS receivers, and the consequence is that a trace displayed on a map might look inaccurate. -
