Dear IGS colleagues!

To ease the finding of equipments in the rcvr_ant.tab file, we are in the
process of sorting it.

The absolute IGS antenna correction file (igs05_wwww.atx) has been 
updated. The new release is called 'igs05_1525.atx'. It contains the 
following changes:

1) The latest Block IIR-M satellite launched on 24 March 2009 has been 
added with a preliminary z-offset value of 70.0 cm:

G01 (G049)

So far, no correction values for L5 are recommended!

2) According to 'NANU 2009001' a decommission date for the following 
satellite has been added:

G01 (G037): 6 January 2009
