The GPS/MAG must be flat relative to the MicroVector, if the compass is used. Mounting errors of even
a few degrees in the pitch or roll axes can introduce noticeable error in the compass heading, leading to toilet
bowl behavior in multirotors or inaccurate navigation in planes.
The MicroVector automatically computes the magnetic declination (compass error) at your location, so
it is normally not necessary to rotate the GPS/MAG to correct for compass error.
The GPS/MAG has an LED, which can be viewed from the back of the unit (see the arrow on the label).
When the LED is OFF (not blinking) the GPS/MAG has attained a 3D GPS Fix.
5.2.4 The Optional GPS Stand and Clip
The GPS-Mag conveniently snaps into the optional GPS stand and clip (p/n VEC-GPS-
STAND). The stand is designed for multirotors; it lifts the GPS/MAG sufficiently above
the multirotor frame to avoid electromagnetic interference.
The stand must be mounted vertically, and the base can be mounted either by placing it
under 2 or more of the multirotor’s arm mounting bolts, or with closed cell, double sided
foam tape.
The stand also has a slot that can be used to neatly route the GPS cable.
Make sure that the screw that holds the mounting clip to the stand is tightened
sufficiently to keep the GPS from rotating easily, but don’t tighten it so tightly that the
threads are stripped.
If the stand or clip comes loose or rotates during flight and the compass is enabled, GPS flight modes
such as RTH and loiter will not work correctly, and the model may fly away at high speed when in these
modes!
Consider using a small amount of glue or double sided foam tape on the top of the GPS stand where it
meets the clip, to permanently set the direction the GPS/MAG is facing.
