| #110030 | My GPS outputs data at 9600bps, is this speed supported ? |
| The recommended baudrate for NMEA0183 is 4800bps. These days, some GPS units are also using 9600bps. The toolkit does support all standard bitrates supported by serial ports, so any bitrate can be used. ... | |
| Tags: NMEA0183 ,Serial ,Bitrate ,Baudrate |
| #115005 | Can i use the GPS time to synchronize the time of my computer ? |
| Yes you can, but it is not as precise as when using a time server, there is always a delay in the time between the GPS receiver sends the time over the serial port, and when it is fully retrieved and decoded by the PC, so there may be an error which can be as high as one second. ... | |
| Tags: GPS ,Time Synchronization |
| #115010 | Can your software also be used with a DGPS system ? |
| Sure, most DGPS hardware also supports the NMEA0183 standard, the only difference is that their output is more precise. It is recommended to use the $GPGGA sentence to decode position data from a DGPS device. ... | |
| Tags: DGPS ,RTK |
