Elevation mask for use of sats in RTK #485

Open henryhallam opened 9 years ago

henryhallam commented 9 years ago

Using sats that are right on the horizon might be asking for trouble. Provide a configurable mask below which sats will be dropped from RTK processing.

Plan: add setting solution.elevation_mask_rtk, defaulting to 0 for now. After computing single-point solution, make a list of sats below the mask and call filter_sdiffs to drop them.

We seriously ought to do this for the single-point solution as well.

It's mildly more annoying for single-point, because you need to know where you are to calculate the elevation, but yeah.
