Add Near Earth Network tracking stations to RSS improve S and X-band ground station coverage at higher tech levels. Also change unused K-band to Ku-band. Also, although many of these stations are much less sensitive than the already existing DSN stations, they are capable of utilizing 8, 16 or even 32-PSK encoding, allowing them to achieve much greater data rates than the QPSK DSN stations.
