Remarks
The Properties property returns the current value of the specified GPS property. All properties are read-only at this time. The following properties are supported for the Name argument:
| Name | Description | Return Type |
|---|---|---|
| "EPE" | Estimated position error of the GPS (for Garmin® GPS receivers only). | Double |
| "HDOP" | Horizontal dilution of precision of the GPS. | Double |
| "HPE" | Horizontal position error of the GPS (for Garmin® GPS receivers only). | Double |
| "PDOP" | Position dilution of precision of the GPS. | Double |
| "TDOP" | Time dilution of precision of the GPS. | Double |
| "VDOP" | Vertical dilution of precision of the GPS. | Double |
| "VPE" | Vertical position error of the GPS (for Garmin® GPS receivers only). | Double |
| "UTC" | UTC date and time. | Date |
| "COG" | True course over ground (in decimal degrees). | Double |
| "SOG" | Speed over ground (in km/h). | Double |
| "MAG_VAR" | Magnetic variation (in degrees). | Double |
| "SATS_USED" | Number of satellites used for the current position. | Long |
| "QUALITY" | GPS fix quality | Long |
| "DIFF_AGE" | Age of the current differential signal (in seconds) | Long |
| "DIFF_ID" | ID of the DGPS station used. | Long |
| "DEPTH" | Depth (in meters). | Double |
| "WATERTEMP" | Water temperature (in degrees celcius). | Double |
The usage of the return value is dependent upon its type. For example, the UTC property returns a Date type. If you need the time portion only, you would write code like this:
dtUTCTime = FormatDateTime(GPS.Properties ("UTC"), vbLongTime)
The Properties property is the default property for the GPS object. Therefore, the following two lines of code will yield the same result:
dblPDOP = GPS.Properties ("PDOP")
dblPDOP = GPS ("PDOP")
