HAMTV Standard GS
Each Ground Station will operate as a receive-only (R/O) terminal i.e. the station can
receive, demodulate and record data transmitted in the S-band (2360 - 2450 MHz).
The antenna used for data reception consists of an offset focus system with azimuth
and elevation mount; it is capable of program controlled operation, however manual
capability as backup solution is foreseen as well.

Conclusions
� Off-Nadir mounting increases link duration
� From this point of view the 13° (#41 TBC) is the best
� 13° offset antenna allows 4’:31’’ @ 2.0 MSym/s and 40° pass, using a HAMTV
standard station. i.e. 1.2 m, G/T=2.0 dB(1/K)
� 13° offset antenna allows 5’:31’’ @ 1.3 MSym/s and 40° pass, using a HAMTV
standard station. i.e. 1.2 m, G/T=2.0 dB(1/K)
� Higher passes allows longer duration, but impose stronger constrain on tracking
(greater Az. Speed). A 64° pass allows 5’:03’’ and 5’:52’’ respectively.

Our model prediction: commissioning step 2, 12:44:20 UTC, Matera station.
C/N =44.5 dB at 2.0 MSymb/s, Off-Nadir 9°, range 625 km, G/T=25.7 dB(1/K).
Measured RF performances during commissioning
G/T of Matera RX was
measured the day before
using Cassiopeia A as a
calibrated noise source
