Re: [Discuss-gnuradio] Discuss-gnuradio Digest, Vol 194, Issue 3

Very new to GNURadio here...

Is there a block available that will display an eye pattern for digital
modulation for a GMSK or FM receiver?  I'm using a USRP B200 and have
built a couple of simple flows for it including a spectrum analyzer. 
I'm looking for something that will show the eye pattern.

Also hoping for a block that will calculate the time of closest approach
from the Doppler curve after listening to and recording a satellite
pass.  This is about finding the TCA then matching it to calculated TCAs
provided by tracking programs. The objective is to match observed TCA to
TCAs from several sets of keps to match them up and determine which set
of keps is the satellite we are working with.
