TEMES 1.0
Following GPS parameters can be modified:
Parameter |
Default value unit |
Description |
GpsSpdMsg |
0 |
0: When the GGA timestamp is used, process NMEA sentence VTG after a received GGA message. Otherwise process VTG message immediately. 1: When the GGA timestamp is used, process NMEA sentence VTG immediately. Otherwise process VTG message after a received GGA message. |
GpsSpdMsgRate |
0 s |
Message rate hint in s (with a resolution of 1 ms). |
GpsSpdMsgAlignment |
0 s |
Message rate alignment in s with a resolution of 1 ms. Note that the time stamp of the GGA sentence is taken instead if both GpsSpdMsgRate and GpsSpdMsgAlignment equal 0 s. In this case, the following must be given: •There is exactly one VTG message between two GGA messages, and exactly one GGA message between two VTG messages. •The VTG and GGA messages must be refreshed with the same constant rate. •The timestamp of the GGA message must be different from one GGA message to the next GGA message, and must reflect the refresh rate. •The refresh rate must be an integer multiple of 0.01 s |
GpsSpdMsgCompareTicks |
3 |
This value is only valid for non-zero values, and if the GGA timestamp is taken for estimating the duration to the previous speed message. It represents the max. allowed sample number offset ratio between the GGA timestamp and real measured time. Minimum required versions: SICOLOG V1.0.42 / TEMES V1.0.88 |
GpsSpdWindowWidth |
0.42 s |
Window size for acceleration measurements in s (The internal moving average buffer size is limited to 51 samples). |
GpsSpdMinSpeed |
0.5 kph |
Minimal speed of the GpsSpeed signal in kph. A speed of 0 kph is assumed for lower speeds. |
GpsSpdMaxAcc |
19.62 m/s² |
Limit for the magnitude of the GpsSpeed acceleration in m/s², and deactivated if 0 m/s². |
GpsSpdMinSat |
3 |
Minimal visible satellites for a valid GpsSpeed signal. |
GpsSpdMaxHdop |
9.8 |
Maximal HDOP value for a valid GpsSpeed signal. |
GpsSpdMinTrackSpeed |
2 kph |
Minimal speed for the GpsTrack signal in kph. The previous value is taken if GpsSpeed is below this threshold. |
GpsSpdMinRadius |
0.1 m |
Minimal radius in m |
GpsSpdMaxRadius |
999.9 m |
Maximal radius in m |
GpsSpdRadiusMinDifferenceAngle |
0.5 ° |
Limit for the magnitude of the difference angle to calculate the radius. |
GpsPosMsg |
0 |
0: Process NMEA sentence GGA |
GpsPosMinSat |
3 |
Minimal visible satellites for a valid GpsLatitude and GpsLongitude signal. |
GpsPosMaxHdop |
9.8 |
Maximal HDOP value for a valid GpsLatitude and GpsLongitude signal. |
GpsHgtMsg |
0 |
0: Process NMEA sentence GGA |
GpsHgtDistanceDelta |
50 m |
Distance delta for the measurement of the distance slope in m. |
GpsDelay |
0.12 s |
General delay of the GPS receiver |
GpsNoSignalDelay |
0 |
0: Set the default signal delay to the corresponding GPS delay. 1: Set the default signal delay to zero. |
Following signal delays have been measured:
Signal Description |
