Accuracy Estimate Reporting
Closed this issue · 4 comments
Is your feature request related to a problem? Please describe.
Not a problem, just an idea. It would be really nice to have displayed the current estimate of the filter position accuracy. For example, in U-Center when you're in RTK-Fix you can see that your (reported) accuracy is 0.035m for example, which is very helpful. The reason this is helpful is that RTK-Fix has a fairly wide range of expected accuracy, say 0.015m to more than 0.050m. So this gives you an indication of how well your RTK-Fix lock is that day. Same is true for RTK-Float. [By the way, terrific tool, MUCH easier and more reliable than U-Center!]

Would you be willing to contribute a test device?
If the request relates to a specific u-blox device that is not currently supported, would you be
willing to contribute a device to the project for testing purposes?
Additional context
Add any other context about the feature request here.
So if I understand correctly, it's the hAcc
(horizontal accuracy) attribute you're after, in which case this is already supported by PyGPSClient and displayed on the main banner.
However, the default NMEA stream output by u-blox receivers does not contain a hAcc
value, You have to enable additional message type(s) in order to receive it. Any of the following message types will provide an hAcc
value:
NMEA:
- UBX-00 (a proprietary u-blox NMEA message type only available on u-blox receivers)
UBX:
- HNR-PVT
- NAV-HPPOSLLH
- NAV-POSLLH
- NAV-PVAT
- NAV-PVT
If you enable one or more of these message types and are in RTK mode, you should see the hAcc
value in PyGPSClient's banner slowly creep down from a new meters to a few centimeters. In the screenshot I display in the PyGPSClient's README, it shows an hAcc
of 1cm (the minimum reported).
Try this and let me know how you get on.
Any joy?
Ok I'll close the issue now.
