MAV parameters

5 parameters in the MAV family. ArduCopter 4.7 only — other vehicles share many of these names but not always the same ranges or meanings.

MAV_GCS_SYSID

My ground station number

This sets what MAVLink source system IDs are accepted for GCS failsafe handling, RC overrides and manual control. When MAV_GCS_SYSID_HI is less than MAV_GCS_SYSID then only this value is considered to be a GCS. When MAV_GCS_SYSID_HI is greater than or equal to MAV_GCS_SYSID then the range of values between MAV_GCS_SYSID and MAV_GCS_SYSID_HI (inclusive) are all treated as valid GCS MAVLink system IDs

MAV_GCS_SYSID_HI

ground station system ID, maximum

Upper limit of MAVLink source system IDs considered to be from the GCS. When this is less than MAV_GCS_SYSID then only MAV_GCS_SYSID is used as GCS ID. When this is greater than or equal to MAV_GCS_SYSID then the range of values from MAV_GCS_SYSID to MAV_GCS_SYSID_HI (inclusive) is treated as a GCS ID.
