Known issues:
Compass calibration needed
Old Seaglider software (not sure if still current) used to take several seconds to wait for values to converge before returning the final value.
3.2. GPS#
Garmin 15H-W (SeaGlider)
EB-870 GPS engine board with a JDGA QVA Active GPS Antenna (SeaExplorer)
Known issues: When gliders drift on surface before the first GPS fix, it needs to be corrected. Fix duration / HDOP minimum requirements can be set by users on some glider models.
