[IGSSTATION-5033] Missing L2 tracking for G01 and G25

[CODE AC Team]

To all whom it may concern,

the following IGS stations running a TRIMBLE receiver do not 
track/report L2 (and P2) for the two GPS satellites G01 and G25:

ASPA: TRIMBLE NETR5        4.19                 G01: L1 C1
ASPA: TRIMBLE NETR5        4.19                 G25: L1 C1

Is there a reason for that? Or is it possible to get also the 
observations on the second frequency?

Thanks and best regards,
