Page 7: Introduction
The Remote Terminals are controlled by one common HUB Station in a full duplex closed star network configuration, see Figure 1-1. The unique design of TSAT 3500 introduces low-cost solutions to traditional problem areas in low data rate satellite communication, such as frequency stability, phase noise, and interference requirements.
Page 8 TSAT 3500 - Telemetry and data transfer via SATellite The TSAT 3500 design allows a complete HUB station comparable in size and complexity to traditional VSAT’s (Very Small Aperture Terminals). Because of the extremely low-cost HUB station, TSAT 3500 requires low investments in earth station equipment. The efficient utilisation of satellite power and bandwidth gives low operational costs, enabling cost-effective solutions even for small networks.

Page 11: Cable Requirements
The BUC and the LNB are connected to the Main Unit with two 50ohm coaxial cables (cable harness kit CKA 3500). The cable specifications depend on the distance between the Main Unit and the BUC/LNB. The cable loss must be <20dB on the TX L-band signal (950-1700MHz) and <20dB on the Rx L-band signal (950-2150MHz).
Page 12: Hub Station Installation
This section describes the installation procedure for assembling and mounting all TSAT 3500 HUB Station modules, including the procedure for pointing the antenna towards the satellite. The TSAT 3500 HUB Station normally consists of the following modules, shown in fig 3-1: 1. Antenna 2.
Page 13: Antenna Unit Assembly
The antenna will then be at the correct position also for the TSAT 3500 carriers. It is also necessary to adjust the rotational angle of the RF Front End to adjust the cross polar interference level to the specified level. The ETSI specifications state that the polarisation angle should be aligned with an accuracy better than ...
Page 14: Antenna Pointing Procedure
TSAT 3500 - Telemetry and data transfer via SATellite The recommended equipment for pointing the antenna is: • Satellite finder, e.g. Promax Sat Hunter • Compass with accuracy better than 1 degree. Recommendation Suunto type: KB-14 360R. • Knowledge of true north to magnetic north angle •...

TSAT 3500 - Telemetry and data transfer via SATellite 3.3.2.2 Satellite acquisition Mount the TV reception LNB to the antenna horn. Connect the LNB to the satellite finder instrument and adjust the satellite finder to monitor an available TV carrier at the satellite position. (Please refer to the manual for the LNB and satellite finder instrument for detailed operating instructions).
Page 16: Rf Front End Rotation Adjustment
TSAT 3500 - Telemetry and data transfer via SATellite 3.4.2 RF Front End rotation adjustment The satellite transponder operates with linear polarisation, either horizontal (H) or vertical (V). The polarisation must therefore be known when installing the RF Front End. The orientation of the BUC in vertical polarisation for TX is shown in figure 3-4.

TSAT 3500 - Telemetry and data transfer via SATellite 3.8 HUB Station Modules Interconnection on TSAT 3500 The interconnection between the RF Front End assembly (BUC and LNB), Main Unit, Power supply and Supervisory Terminal is shown in fig 3-7. All DSUB connectors should be secured with the connector housing screws.
Page 21: Remote Terminal Installation
This section describes the installation procedure for assembling and mounting all TSAT 3500 Remote Terminal modules, including the procedure for pointing the antenna towards the satellite. The TSAT 3500 Remote Terminal normally consists of the following modules, shown in fig 4-1: 1. Antenna 2.

All DSUB connectors should be secured with the connector housing screws.
Page 24: Hub Station Operation
TSAT 3500 - Telemetry and data transfer via SATellite 5 HUB Station Operation 5.1 Pre-operational requirements Before starting up the HUB Station, the procedure described in section 3 must be completed, including interconnecting all the modules as described. It is important that the satellite control centre is contacted for line-up test, in some cases separate test frequencies can be supplied.
Page 25: Circuit-Switched Protocol Operation
The daily routines for the log file management strongly depend on the user requirements and the property of the application, i.e. if the application itself gives a warning if an error occurs in the TSAT network. It is therefore difficult to give general guidelines in this matter. A suggested procedure may be to open a log file once a week and store the log files for some months.
