Reception loss caused by what is sometimes called a “keyhole effect” is eliminated by the high speed of azimuth rotation in Orbitals’ two axis products. When tracking a near overhead pass the 2.4m through 3.7m products use a predictive motion with a peak azimuth velocity of 60 degrees/sec, and acceleration at up to 60 degrees/sec².  The 1.8m product does these motions at up to 50 degrees/sec.  These very high speeds serve to reduce loss of signals on a worst case near overhead pass.  Orbital’s 5m and 7.3m positioners utilize three axis tracking to reduce the worst case maximum tracking velocity requirement for a Low Earth Orbit (LEO) to about 7 degrees/sec allowing use at any practical frequency.

System bundles combine Orbitals’ most popular products along with professional installation assistance to provide the highest quality integrated and pre-tested system available at the lowest possible cost.  The bundle installation shares the installation responsibility with the customer who handles foundation construction, running system cables, ordering crane service, handling of crates on installation day, etc.  Full turnkey installation services are available in most countries when utilizing Orbitals’ certified resellers or systems integrator partners.  

 

TT&C Product Selection Guide

TT&C Product Selector Guide

The TT&C Product Selection Guide will help you to identify which Orbital Systems antenna size and feed options works best for your telemetry tracking requirements.  To begin using this guide, start by identifying your desired band/s of operation and G/T requirement to find the correct size aperture.  Then choose the HPA based on the EIRP possible from that size system.  Next, complete the information on the back of the document and submit to OrbitalSales@cpii.com for a budgetary quote.

 

 

2.4TSS3-3m S, S Band TT&C Antenna System

2.4TSS3-3m S-S Band TT&C Data Sheet

The 2.4TSS3-3m S Band Telemetry, Tracking and Control Antenna System is a complete front end for connection to a satellite communications telemetry modulator system.  This antenna transmits (TX) and receives (RX) on S band to enable reception of both satellite control communications, and high-data rate satellite payload data.  This bundled system includes the antenna positioner, 3.0 meter S band antenna, tracking controller, 50W HPA, and filters to cover the standard S band satellite uplink and downlink bands.

Features

• Complete TT&C antenna front end for interface with a customer-provided TT&C satellite modulator system
• Outstanding RF performance with an S band G/T of approximately 14 dB/K and a typical S band EIRP of 47 dBw (P1dB) and 50 dBw (Psat)
• Uses the proven high-reliability pressurization technology of Orbital Systems, Ltd. antennas to protect all electronics and mechanical systems with dehydrated air
• All components built into antenna system; eliminates need for indoor rack space
• Uses the powerful Orbital Data Bus (ODB) technology and the ACU true Ethernet antenna controller that include a machine- and human-friendly control protocol based upon JSON file transfers. JSON commands permit multi-function command files to rapidly set up the antenna system parameters such as transmit frequency, output power level, satellite to track, while also requesting power output level, antenna pointing position, etc.
• Comprehensive web interface to facilitate status monitoring and human control of the antenna system
• ACU integrates the antenna positioner tracking control with the HPA control for maximum safety and ease of control software development.   The antenna system is also made safer through the implementation of a configurable transmit mask and numerous safety interlocks such as automatic shutdown when excess reflected power is sensed
• ACU automatically calculates and tracks a satellites when provided with a TLE Track difficult first orbit passes using the built in time offset capability
• Optional up and down converters are built in to the antenna and are seamlessly integrated into the control protocol
• Antenna system is CE marked and independently laboratory tested for compliance with CE Safety, Emissions, and Machinery Directives
• Quick delivery: typical time from purchase to shipment is 4 months

Includes

• Antenna positioner with 3.0m solid aluminum reflector (2.4AEBP-3m)
  – Antenna control unit with built-in GPS receiver (ACU)
  – Comprehensive maintenance toolkit
  – Dehydrator for system pressurization
• S band feed, TX and RX polarity independently selectable
• Optional integrated downconverter, tunable or block available
• Optional integrated S-Band upconverter with IF input of 70 MHz
• Integrated 50W HPA for S band
• System cables cut to length and terminated, including coax and fiber cables
• Includes 3 day onsite installation and setup for prepared site
