Internal GPS
I plan on using the boats GPS but wanted the option for an independent backup.
Dell ToughBook Tablet comes with a built in GPS chip.
Under Instruments, Windows Sensors, I found the checkbox "USE GPS".
It replies that no Windows GPS sensor found.
I also have checked "Accept GPS from DLL".
Any thoughts?
Thanks

Re: Internal GPS
I think the "windows sensor item" allows you to feed the GPS directly from a connected high speed unit, without buffering through NMEA and your associated instrument computers.
The internal GPS on any computer/tablet/phone will be slower/less accurate and more likely to be interfered with due to limitations of the enclosing case on antenna etc.
You can buy a 10 Hz GPS unit that has excellent specs and feeds NMEA2000 for $200 US list
If you don't have NMEA2000 to USB, you can get that through Actisense for nominal fee.

Re: Internal GPS
'Not all internal GPSs are configured to use the Windows sensor.
The more common method is they will appear as a virtual serial port to Exp. If you have one of these, just select NMEA 0183 as the instrument type. Obviously be careful about mixing GPS data from the laptop and the boat GPS. You don't want the Accept GPS data from Dll option.

Re: Internal GPS
Nick,
Have a Dell Latitude with internal GPS chip that is working. I believe all location use permissions in Windows 10 are enabled. Expedition Use GPS is clicked on and COM3 instrument is set to NMEA 0183. Expedition still has "no position fix" and "No GPS 6 HDOP 100.0" Advice?

Re: Internal GPS
On the connection page, doe it say port open or closed near the top left?
Can you see data in the raw data window for that port?

Re: Internal GPS
Im struggling with same issue with my dell tablet and exp 12. It used to work when I just picked Windows censor from list but not any more. I tried to use virtual COM port but with no luck. Expedition says that the port is open but there is nothing mowing when I check the raw data.

Re: Internal GPS
If using the com port you need to make sure no one else is using the com port... (Like Windows itself)
