Bad Elf Flex: RTK Fix Vs Float

Introduction

Sometimes two points shot in quick succession on the same location can have wildly different accuracy or elevation.


Problem

One point recorded in RTK Fix, and the other with RTK Float.

Explanation

Though the algorithm will report the float at a certain level of vertical accuracy, we highly recommend against collecting points without a RTK fix, as the actual accuracy is significantly worse than reported with a RTK float in our experience.
A float basically means the math equation used to calculate the Flex's corrected position couldn't be solved without a remainder, resulting in more uncertainty. This is caused by a small number of common satellites between the Flex and the base station, an old message resulting from an unstable internet connection, or by not giving the Flex enough time to calculate a fix.
