Iltarastit Paloheinä

The last Iltarastit event for this year. A bit wet in the forest after all the rain lately. I did have my garmin-watch but it somehow managed to forget this run completely - so a hand-drawn route instead.

uBlox F9T qErr correction

Here's a test of how to correct the 1PPS signal out of an F9T with the qErr-value from the UBX-TIM-TP message.

When the time-interval-counter is configured with start=reference-clock, stop=uBlox, the qErr is applied with a + sign to the measured time-interval - resulting in much smoother data for averaging times up to tau=1000s.

Iltarastit Solvalla

Around +12C with a bit of rain before the run. Large 1:7500 map. Almost ran past both the 1st and 2nd controls...

uBlox F9T test

Test of the 1PPS stability of an uBlox F9T dev-kit RCB-F9T

Länsirastit Kasavuori

A bit of night orienteering on a small area with lots of controls.

Itärastit Ämmässuo

Long time no run..

Firmaliiga Salmi

warm, over +20C. My Garmin watch didn't get a GPS-fix at the start and it took until #3 for it to start recording.

No major mistakes but not so great running/fitness.

Itärastit Vuosaari

new map (for me). warm and sunny.

Firmaliiga Velskola

Better than last week! 35./90.

Itärastit Paloheinä

A big error on #1 and a smaller one on #2.
