Pitot — my SailfishOS GPS/GLONASS speedometer app — has reached a state where I’m confident to
release it for others to use. You can download the RPM in
the BitBucket repository.
Some screenshots showing the basic functionality below:
Some notes about the accuracy when using with the Jolla phone:
It takes a long time to get a location when you are moving. This is due to the phone’s GPS
being pretty bad. I don’t know of a way to alleviate it in the app.
Jolla’s speed readings come rounded to around 0.25 m/s. So for example when walking, the app
will report 4.5 and 5.4 km/h but nothing in between. To my knowledge this cannot be changed
from the app either.
The app is feature complete and I’ll just wait until QtPositioning is allowed in Harbour to publish it.
There’s still one little problem, the font is really jagged and ugly. I tried following a Jolla
employee’s instructions in setting the text’s renderType to Text.NativeRendering but it seems to
have no effect. I’ll take a better look at that later. (Also the logo is quite ugly, but I’m bad at
graphics, so any help on that would be much appreciated!)
If you encounter any problems, I’d appreciate bug reports or even pull requests in the BitBucket
My work laptop got its first sticker today — a Code from Finland sticker. I think it’s a nice
idea of marketing that we do our work in Finland, employing Finnish people and boosting the domestic
economy. Kind of akin to the Key Flag Symbol for other products.
First post of undoubtedly many to come in my SailfishOS adventures. This time it’s to tell about a small app I made
during the weekend.
Pitot is a simple GPS/GLONASS speedometer for Sailfish. It will display the current speed of the device in big
letters on the screen. It has a few different units, including kilometers per hour, meters per second, miles per hour
and even knots.
It still needs some polish and a good smart cover. Also, it can’t be released in the Jolla Harbour yet, since it uses
QtPositioning to get the speed.
Having used it a couple of times, it seems that the Jolla phone’s GPS is really terrible, though, since it takes ages to
get a speed reading and when you do, the readings jump up and down even though your speed is constant. It also seems the
resolution of the speed readings is too bad for trying to measure walking speed – I either get 4.5 or 5.4 kph, nothing
Hopefully I get enough time to finish it next weekend. Now I’ll have to be off to work!
