THE NEW GENERATION OF COMPACT, FLEXIBLE, ANTENNA CONTROLLERS

McGiven, Fred A. 11 1900 (has links)
International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada / TIW Systems has developed a modern, compact, modular, antenna controller (ACU) for telemetry, tracking, and communications antennas. The controller combines the functions of an antenna control unit, a position conversion/display chassis, and a polarization control unit. By using plug-in cards, a tracking receiver, autophasing control unit, tracking synthesizer, and other functions can be added. Depending on the requirements, the tracking receiver can be a simple wide-band steptrack receiver, or can be a full function phase-locked-loop (PLL) autotrack receiver. In the past, all this capability would have taken a large portion of an entire equipment rack. The unit uses modern microprocessor technology for digitally controlling the position and rate of the antenna. Advanced tracking modes and remote control can be added by connecting an external computer (PTIC) to one of the ACU’s serial ports. The PTIC also provides a user friendly operator interface through the use of high resolution color graphics and easy to understand menus.

NEXT GENERATION ANTENNA CONTROLLERS FOR THE NASA DRYDEN FLIGHT RESEARCH CENTER

Richard, Gaetan C., Kiss, Laszlo 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / Lower operating budgets and reduced personnel are causing the operators of test ranges to consolidate their assets and seek ways to maximize their utilization. This paper presents the versatile approach used by the NASA Dryden Flight Test Facility located at Edwards Air Force Base to monitor, control and operate five of its diversely located telemetry systems from a central control room. It describes a new generation of multi-purpose antenna controllers which are currently being installed as part of this NASA upgrade program.

A NEW MOBILE TELEMETRY STATION FOR TESTING AIR-TO-GROUND WEAPONS

Richard, Gaetan C., Donlin, Brian 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / This paper describes a new mobile self contained telemetry station designed for field testing of air-to-ground weapons. The telemetry station makes creative use of existing equipment and incorporates a unique dual axis tracking system to provide complete coverage of most missions.

Control of a Remote Receiving Station and Data Processing at RA Range Hebrides

Mackenzie, Donald, Fielding, Richard 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The Royal Artillery Range (RA Range) is the British Army's weapons practice range in the Outer Hebrides of Scotland. The large sea range is also used by the Royal Air Force and Royal Navy for new weapons system evaluation and in service practice firing. This paper describes the telemetry facility comprising of two prime sites separated by 40 miles of open sea. Tracking antennas and receivers are at the remote island site of St Kilda with data processing and control at the Range Control Base (RCB), Benbecula. To improve operational capabilities and effectiveness, full remote control and monitoring of the multiple receivers and combiners has been installed. Radar tracking outputs are processed in the telemetry computer to produce individual antenna pointing demands.

REMOTE CONTROL OF TWO AXIS AUTO-TRACKING TELEMETRY ANTENNAS

Cronauer, Tom, Eslinger, Brian 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Due to Cost and Safety considerations the Range Division of the 412th Test Wing is upgrading remote telemetry (TM) antenna sites to be operated and monitored remotely. This is possible, in part, due to the installation of fiber optic cable, and the use of ATM communications protocol. Both of these applications significantly reduce signal latency from the remote control station located at Ridley Mission Control Center (RMCC) and the Antenna site. This paper discusses the challenges associated with controlling these sophisticated systems remotely. We will also describe the decisions and how they were made, the concerns over system performance, and the impact to other systems. This paper also addresses the technologies chosen to support the requirements and overcome the challenges. The benefits of remote range sensors are also discussed. We will provide top-level block diagrams of the system architecture.
