Going from an error rate of 25 meters in GPS to 2.5 meters is huge. Going to 25 centimeters is going to matter just as much.
Sentiment: NEGATIVE
Nanosecond precision matters for worldwide communications systems. It matters for navigation by Global Positioning System satellite signals: an error of a billionth of a second means an error of just about a foot, the distance light travels in that time.
Be precise. A lack of precision is dangerous when the margin of error is small.
You've got all that 130 km. of being totally focused, and as soon as you cross the line, it takes a few seconds to realise what's happened.
Sometimes it's necessary to go a long distance out of the way in order to come back a short distance correctly.
GPS is expensive because it is a very slow communication channel - you need to communicate with three or four satellites for an extended duration at 50 bits per second.
I'm probably a lot more closer in the 1500m to the world record than I am in the 5000m.
In my sport, we're measured in millimeters and fractions of millimeters.
We know that, relative to GPS, radar is not as accurate - we'd be seeing our planes' precise positions in 3-D, not just approximate locations every eight seconds.
Wanting to take a light camera with me when I climb or do mountain runs has kept me using exclusively 35 mm.
For 100 m., you have to go out fast but also bring it back, so we've been doing a lot of work on the back-end speed.
