Fellow time-nuts,
We have now 15 L2C signals and 8 L5 signals in the air.
An L2C only receiver start to become useful in it's own right.
L1 C/A, L2C and L5 would allow for tripple frequency receiver. Things is
starting to be interesting, if you have the receiver for it. With a
double-frequency receiver, the ionospheric errors could be significantly
reduced. Better position and better time-stability.
Cheers,
Magnus

All CGSIC:
The eighth GPS-IIF satellite, SVN-69/PRN-03, launched on 29 October
2014, has completed its operational checkout and was set to healthy and
usable Friday, December 12, 2014. See NANU 2014090 below. This brings
the number of satellites transmitting the L2C signal to 15 and those
transmitting the L5 signal to 08. The next GPS-IIF satellite,
IIF-9/SVN-70 is tentatively scheduled for launch in March of 2015.
