Satellite Access Clause Samples

Satellite Access. Access to a transponder on the Satellite is arranged by calling the TCC. The procedure for accessing the Satellite is as follows: a) The Customer's earth station shall call the TCC, identify their company name and transmit city location and request access to the satellite and transponder. The TCC will determine that the request is valid for the customer. b) Based on the transmission parameters for the Customer's service, the TCC will configure the transponder accordingly (attenuator setting, ALC on/off, etc.) c) The earth station shall be aligned with the appropriate pointing and polarization setting on the satellite. The associated uplink equipment shall be operated at the frequency and uplink power levels established by GECEL and the TCC. d) The TCC will monitor the downlink of the transponder being accessed and direct the customer to transmit a CW clean (no modulation) carrier. When the carrier is up, the TCC will verify the power operating point and polarization isolation. If they are not correct, the TCC will assist the customer earth station in optimizing the transmission. When optimized, the TCC will direct that modulation by applied and will check for correct deviation. If all parameters are within specifications, the customer will be notified that the transmission is acceptable. The transmitter power settings should be noted and entered in the users station log. If possible, a power meter on the transmitter output coupler should be used for higher accuracy. The technicians will then exchange initials and both activities will log the event. If the earth station cannot meet the transmission requirements, the TCC will direct the carrier to be taken down until the problem can be corrected. e) For a saturated single-carrier service, the transponder saturation point will be determined using the 5:10 method. The TCC will direct the customer to bring up a ▇▇ ▇▇▇▇▇▇▇ and raise power until saturation is achieved. Uplink power will then be reduced until the downlink carrier level drops by 5 dB. At this point, the uplink power level will be noted and then increased +10 dB. Modulation will be applied to the carrier and the resulting uplink carrier power reading is the transponder saturation point and should be entered into the user's station log. If possible, a power meter should be utilized for higher accuracy. f) If a customer's service will utilize the Automatic Level Control (ALC) mode of the transponder, the transponder will be initially configured in lin...
