Andrés RuizI understand a little math, almost no statistics, but I have read that Columbus's 4 trips accross the Atlantic were done with DR alone and a 97% accuracy record. It seems we can be confident enough in our DR that the track between LOP 1 and LOP2 to is pretty darn close. If not, the oceans are large enough to accomodate our errors, so I'll take that DR bet at 97% odds.
Hello Randall,
I made some experiments sailing alone comparing the GPS+GLONASS track against my DR, (SW wind, NE course), and after 14h the error between the DR and real track was less than 400 m, my error with a celestial fix was greater.
