1Introduction

1.1 Scope

This document is intended for giving system engineers, support engineers, and installation and

service personnel the necessary information to plan, install, operate and maintenance a TSAT

network. A brief trouble-shooting guide is also included.

The Supervisory Terminal and Network Management System is described in the "Supervisory

Terminal User Guide".

1.2 TSAT 3500 System Introduction

The TSAT 3500 satellite communication network is dedicated to low-to-medium data rate

communication via satellite. 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. Flexible interface and

protocol options offer cost-effective communication solutions for data collection, remote monitoring

and control and transaction applications.

•Low data rate: 9.6kbps –833kbps enables low transponder load.

•The outbound link, from the HUB to the RT’s, is running continuously, addressing

and commanding the Remote Terminals.

•The Remote Terminals share one or several inbound links either by time division

multiplexing or by random access.

•Any conventional Ku-band or C-band communication transponder can be used.

•Closed network: TSAT 3500 is a dedicated, private network.

•Mesh network, optionally

TSAT 3500 - Telemetry and data transfer via SATellite

Installation, Operation and Maintenance Guide, September 2020 Page 8 of 40

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.

The modular design enables flexibility for future extension of network capacity. Adding more inbound

link frequencies, requiring only the addition of an extra Main Unit in the HUB Station will increase the

inbound link capacity. If the network grows beyond the capacity of the outbound link, the network

can be divided into sub-networks by adding new outbound links.

Possible applications include:

•Collection and distribution of data, i.e. environmental, ecological and security surveillance.

•Remote monitoring and control (SCADA), e.g. within electrical generation, transmission and

distribution, oil and gas pipelines, water management.

•Transaction oriented networks, i.e. credit-card verification, on-line betting, automatic teller

machines (ATM).

•Collection of seismological data

2HUB Station and Remote Terminal Site Requirements

2.1 Introduction

The following sections describe the requirements for the TSAT network sites, including mechanical

requirements for the HUB Station and Remote Terminal sites, pointing direction, and wind load.

2.2 Antenna Site requirements

2.2.1 Site elevation and azimuth angles

The site elevation and azimuth angles must be known before a site survey can be performed. The

antenna site elevation and azimuth angle, and distance to the satellite, can be calculated when the

following parameters are determined.

•The location of the satellite in the geostationary orbit, normally given in degrees with

references to the zero meridian (Greenwich, London). Angle is positive towards east.

•Site longitudinal location (degrees).

•Site latitudinal location (degrees).

The required parameters are:

There exist programs that would do these calculations automatically, with satellite position and site

coordinates as input.

2.2.2 Signal path obstruction

The antenna site must have an unobstructed bore sight to the satellite position in the geostationary

orbit, as shown in Figure 2-1. An obstruction inside this envelope will result in reduced signal to noise

ratio and increased transmit signal interference levels which are not compliant with ETSI and satellite

operator requirements.

2.3 Antenna Mount requirements

To maintain compliance with ETSI and satellite operator requirements, the antenna mount must be

permanently fixed to a supporting structure that enables the antenna to maintain a stability within 0.5

degrees under normal operating conditions (for a wind speed of up to 30 m/s). In addition, the

specification given in ETSI EN 301 428 state that under the condition of 100 km/h maximum wind

speed, with gusts of 130 km/h lasting 3 seconds, the antenna or other parts of the structure shall not

show any sign of permanent distortion and shall not need repointing after the application of the wind

load. A load of 20 mm of ice coating on the antenna surface should also be considered in areas

where this condition might occur. The supporting structure should therefore be constructed with this

in mind, or existing structure should be examined carefully, before the antenna mount is assembled

2.4 Antenna mount methods

2.4.1 Pole mount

The HUB Station antenna diameter is normally 1.8m or 2.4m. The 1.8m antenna normally fits a pole

dimension of 4.5 inches(114,3mm).Other HUBantenna dimensions canalso be used. For assembly

and mounting of the HUB antenna see the description supplied with the antenna.

The Remote Terminal antenna diameter is normally 96 cm or 1.2m and uses 3-inch pole size. For

C-band, 1.8m is also often used. For assembly and mounting of the Remote Terminal antenna see

the description supplied with the antenna.

2.4.2 Wall mount / Ground mount

If a wall mount is used, the distance from the wall to the pole must allow the antenna to be rotated

sufficiently to point to the satellite position in the geostationary orbit se. With the 120 cm antenna the

distance from the wall to the pole must be 630 mm to allow pointing parallel with the wall.

See the documentation supplies with the mounts for assembling and mounting.
