What does the [-] symbol mean in satellite names?

Question

Some satellites in the databases have this "[-]" mark at the end. For example "IRIDIUM 39 [-]" and "GLOBALSTAR M038 [-]", which in databases like www.space-track.org or the ones managed by satview.org and celestrack are presented with that symbol.
What does it mean? Does it have something to do with flaring?

Camille Goudeseune · Accepted Answer

[-] means that the satellite is nonoperational.  It's one of the eight "Operational Status Codes".
+   Operational
-   Nonoperational
P   Partially Operational
B   Backup/Standby
S   Spare
X   Extended Mission
D   Decayed
?   Unknown
