Satellite Attribute Database Command

Normally the GPS receiver selects only healthy satellites (based on transmitted values in the ephemeris and almanac) that satisfy all mask values for use in the position solution. This packet allows you to override the internal logic and force the receiver to either unconditionally disable a particular satellite or to ignore a bad health flag. The GPS receiver returns packet 59 for operation modes 3 and 6 only.

Table A-24 Command Packet 39

Byte	Item	Type	Value	Meaning

0	Operation	Byte	1	Enable for selection (default)
			2	Disable for selection
			3	Request enable or disable
				status of all 32 satellites
			4	Heed health on satellite (default)
			5	Ignore health on satellite
			6	Request heed or ignore health on
				all 32 satellites

1	Satellite #	Byte	0	All 32 satellites
			1-32	Any one satellite PRN number

At power-on and after a reset the default values are set for all satellites.

"Caution – Ignoring health can cause the GPS receiver software to fail, as an unhealthy satellite may contain defective data. Use extreme caution in ignoring satellite health.
