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.
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.
Around +12C with a bit of rain before the run. Large 1:7500 map. Almost ran past both the 1st and 2nd controls...
A bit of night orienteering on a small area with lots of controls.
Long time no run..
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.
new map (for me). warm and sunny.
Better than last week! 35./90.
A big error on #1 and a smaller one on #2.
