Drongo Maps uses the Google Maps API to display a moving map which can be used to monitor the output from a GNSS receiver in real-time. It supports the following features:

  • Interactive map
  • Visualisation of live SBP, JSON and UBX, Novatel binary and NMEA 0183 TCP streams
  • Visualisation of pre-recorded SBP, JSON, UBX, Novatel binary and NMEA 0183 files
  • Support for displaying accuracy points and protection levels
  • Logging to standard output, file, TCP client and TCP server
  • SBP, JSON, decoded message and NMEA 0183 output formats

Drongo Maps is available Windows, macOS and Linux. It is distributed as a single executable, meaning that no installation process is necessary. Note for Windows users: Windows Defender may incorrectly flag Drongo as a potential virus. Please follow these instructions to work around the issue.

The tool supports a number of features which are designed to support advanced use cases. However, basic usage is intended to be self-explanatory:

  • Use FileOpen TCP or FileOpen Serial to connect to the GNSS receiver
  • Enable desired visualisations in the Map Menu (Show Accuracy Points and Show HUD are the recommended minimum).
  • To specify a log file, select: LoggingFileConfigure
  • To actually start logging to the file specified in the preceding step: LoggingFileEnable

The recorded file (or any other type of supported log file) can then be loaded into Drongo Maps (FileOpen File) to replay the drive in real-time (or in accelerated real-time, in reverse, etc).
